INTRODUCTION
The SL-2001 isa unique MIDI instrument which combines powerful master keyboard
functions with versatile MIDI processing features Its operating system has been care-
fullydesigned for fast and efficient musicalcontrol ofany MIDI system, from small home
studios to professional stage setups
TheSL-2001islike any musicalinstrument, the more time invested, thegreater the
rewards Once the basic principles ofoperation aie mastered, the many powerful func-
tions are easily accessible It isnot necessary to read and understand every detail ofthe
SL-2001operation guide, but please take the time to scanall ofthe sectionsto gain
awareness ofthe unit's fullpotential
Sections 1 through 4 contain essential information and should be read carefully
Sections 5 through 8 aie reference sections which detail all ofthe powerful functions
available, and may be studied as required.

1QUICK REFERENCE
For basic operation please follow the guidelines below. The SL-2001includes eight demonstration presetswhich may be
used afterthe instrument isinstalled into yourMIDI system.
1.Connect voltage adapter into a power outlet (make sure voltage specification on power adapter matches your line volt-
age). Connect adapter cable to SL-2001 power jack.
2. Connect MIDI cables before switching on any MIDI devices. Touse the demonstration presets, connect a sound module
to each ofthe fourMIDI outputsA-D. Each sound module should be setto receive on MIDI channel 1.
4.Apply power to all MIDI devicesin the system.
5.Switchon the power tothe SL-2001.
Tochange SL-2001presets, make sure that the unit isin Perform Mode (red light onEDIT switch isoff).Tochange the pre-
set, press any ofthe eight PRESET switches. To change to a differentbank,press the left or right arrow switches
(< > ) untilthe desired banknumber isdisplayed before pressing one of theeight PRESET switches. Presets are arranged
in eight banks ofeight, for a total of64 presets (11through88).An optional memory card isavailable which holds 64 addi-
tional presets.
Local controllers (front panel sliders, Star and Alpha switches, footswitches A through C, and control voltage inputs 1 and 2)
will issue MIDI control change commands dependingon the selected preset.
MIDI devices may be switched on and off using the eight ZONE switches.
Toedit a preset, enter EditMode by pressing the EDIT switch. Press the appropriateFUNCTION switch to access the desired
function (press several times if necessary untilthe desired screen appearson thetext display).If a star (*)appears in thedis-
play, an alternate screen may be accessed by pressing theStar switch.Adjusttheparameterwith the appropriatecontrol slid-
er. Tochange parametersfor a specific zone, first select theappropriate zone by using the left and right arrow switches.The
selectedzone isindicated by the zone digit(s) following the preset number.
IMPORTANT:Before the SL-2001 can be effectively programmed for your MIDI system, all MIDI devices must be properly
"installed" into the SL-2001 operating system. Refer to the DEVICES function in section 4 for information on this procedure.
DEMONSTRATION PRESETS
The SL-2001comes from the factory with 8 demonstration presets in locations 11through 18.The demonstration presets are
intended for use with fourMIDI sound modules.Each sound module should be setfor MIDI channel1,and each should
each be on a separate MIDI output.The demonstration presets illustrateseveral ofthe most usefulSL-2001 functions,and
are summarizedbelow. When thedemonstration presets are selected with the PRESET switches, the sound modules should
change programs automatically. The actualprogram number on each sound module may not match the number ofthe pre-
setselected on theSL-2001. These program numbers may be easilychanged; seethe operation guide sectionsonEdit Mode
and the Program function.
DEMONSTRATION PRESET 11:All foursound modules are active and receiving note information from the keyboard. The
ZONE switches may be used to turnoff selected sound modules to hear differentcombinations ofthe modules. The four
control sliders on the front panel are used to adjustthe volume level for each sound module (refer to the CONTROLS func-
tion in section8 for information on programming slidersand control pedals).
DEMONSTRATION PRESET 12:Allfour sound modules are active, but the keyboard isdivided into four zones,with a dif-
ferent sound module active in each zone (refer tothe ZONE function in section8 for more information).
DEMONSTRATION PRESET 13:All four sound modules are active,but each key that isplayed onthe keyboard isassigned
to a different sound module, (refer to the NOTES function in section8 for more information).

DEMONSTRATION PRESET 14:Allfoursound modules are active, butMIDI information formodules 2,3,and 4 is delayed,
with module 2 setfor the shortest delay and module 4 setforthe longest. The two wheel controllers may be used to change
pitch or add modulation; this MIDI data will be delayed along with thenote information, creating a unique effect (refer to the
DELAY function in section8 for more information).
DEMONSTRATION PRESET 15:Thispreset demonstrates the velocityswitchfunction. Fornotesplayed softly onthe key-
board, only the first sound module will play. As the keys are struck more forcefully, module 2, module 3,and finally mod-
ule 4 will sound (refer to the VELOCITY function in section 8 for more information).
DEMONSTRATION PRESET l6: This preset uses only MIDI sound module numbers one and two, and demonstrates what is
known as a velocity cross-fade. For notes played softly on the keyboard, only sound module number 1 should play at max-
imum volume. As the notes are struck more forcefully, sound module 1 willbecome softer, and sound module 2 will become
louder (refer to the VELOCITY function insection8 for more information).
DEMONSTRATION PRESET 17:Thispresetdemonstrates MIDI delay combined with multiple key transpose settingsto pro-
duce an arpeggio forevery note thatisplayed on thekeyboard. Only sound module #1is used in thispreset. For best results,
this module should be capable ofplaying eight or more notes simultaneously (refer to the TRANSPOSE function in section 8
for more information).
DEMONSTRATION PRESET 18:The SL-2001iscapable ofgenerating long MIDI delays with independent time settingsfor
each sound module. This preset has zero delay for the first sound module, and delays of2.5,5,and 7.5secondsfor the sec-
ond, third, and fourth modules respectively.

2BASIC INFORMATION
The SL-2001 MIDI Master Keyboard servesas the central controller for any group ofMIDI instruments and accessories. With
fourMIDI inputsand outputsand powerfulMIDI processing functions,the SL-2001 eliminatesthe need for outboard MIDI
switchers or other devices. Full programmabilitymeans thatyourtime isspent making music, not reconfiguring the equip-
ment.
The SL-2001will command at least eight sound modules (or keyboard synthesizers) simultaneously and at least eight auxil-
iary MIDI devices(audio effects units, mixers, lighting controllers, etc). More thanthirty-two MIDI devicesmay beconnect-
edand selectively accessed underpreset control. Thefour MIDI outputs are completely independent, which means that
sixty-fourMIDIchannelsareavailable.
BACKPANELCONNECTIONS
MIDI INPUTS: Four MIDI inputsare provided to supportseveral additionalperformance devices at once (other keyboards,
guitarcontrollers, sequencers, etc). The MIDI data fromanyof these external sources may be processed and zoned in the
sameway asthe masterkeyboard, oritmay be passed straight through to any ofthe outputs.
MIDI OUTPUTS: The four MIDI outputs will support a large number ofMIDI devices as each output may contain informa-
tion on several MIDI channels simultaneously. A total of64slavedevicesare addressable under preset control.
SWITCHINPUTS: Threestereophone jacks are provided for control footswitches. A double footswitch isincluded with the
SL-2001,and will normally be connected to the SUSTAIN / A input. The SUSTAIN footswitch on the right will functionas a
conventionalpianosustainpedal,while the A footswitch on the leftmay he programmed fora wide range ofMIDI functions.
Its most commonly used functionisto activateor disable one or more zones duringa performance.An additionaldouble
footswitch may be purchased and may beused in either the B/C inputor the (preset) increment/decrement input.Inputs
B/C may be programmedto control zones, issue MIDI control changes, or otherfunctions.For live performance,many play-
ers will want to use three double footswitches simultaneously, in order to effect quick sound changes while playing the key-
board.
Although stereo jacks are used for the switch inputs, a standard normally-open footswitch with a mono phone plug may also
beused. It will function as either SUSTAIN, switch B , or program increment. If desired, the switch inputsmay beused as
voltage inputs.The voltagerangeis from0 to 5 volts DC, with 0 volts corresponding to the footswitch being pressed.
CONTROL VOLTAGE INPUTS: Two inputs are provided for external analog controllers. An optional control pedal isavail-

able from your dealer, or any DC control voltage source may be used. The input voltage range is0 to 5 volts DC, whichcor-
responds to a MIDI control range of0 to 7Fhex.The control pedal ismost commonly used to control volume.
MEMORY CARD
The SL-2001isequipped with a connector for a plug-in memory card. The optional memory card isused to make back-up
copiesofSL-2001presets as well as giving quick accessto an alternate setofpresets. Use ofa memory card for saving inter-
nal presetsisstronglyrecommended. Before performing any SaveorLoadoperation, be sure that the card isfirmly inserted
into the connector as far as it will go. The card may onlybe inserted with the printed sidefacing up. When not in,use,store
the memory cards in a safe place away from excessiveheat ormoisture. | :
The memory card contains a battery which should be replaced after five years ofuse. The plastic clip which holds the bat-
tery may be removed by carefully pulling itfrom the end ofthe card (to the right ofthe memory-protect switch). The bat-
tery should only be removedwhen the memory cardisinsertedin a SL-2001and power isapplied, otherwise the data in the
card willbelost.Contactyour dealerfor replacement battenes.1
MIDI SYSTEMCONFIGURATION
The illustration (facing page) shows.atypical medium-sized MIDI systemconfigured around the SL-2001.Most systemswill
include a combination ofkeyboard synthesizers, sound modules, and effects units. When using keyboards that produce
sound (asopposedto a MIDI control keyboard), setthe instrument to "localoff mode. This will disconnect the sound-gen- /
erating circuitryfrom the keyboard. The instrument can nowbeconsideredastwo devices:a controllerkeyboard with a /
MIDI output, and a sound module with a MIDI input (consult your operation manual for instructions on the "localoff" mode)./'
Asmany as four external keyboards may be connected and used as master controllers for the entire system.
The sound modules should bedistributed evenly among the four MIDI outputs to avoid congesting any MIDI lines with
excessinformation. In the example, two sound modules have been cascaded onMIDI output C, and two effects units are
sharing MIDI output D. When multiple units are onthe same MIDI output, they must have unique MIDI receivechannels,
sothat each can receiveindependent MIDI data from the SL-2001. The total number ofMIDI channels per output must not
exceed sixteen. If a sound module can receive all sixteenMIDI channels simultaneously, itcannot share a MIDI output with
any otherdevice.
Ifthere are morethan four sound modules inyour system,the MIDI-THRU jacks oneachunit can beused toconnectaddi-
tional setsofunits. Ifmore than twelve modules are used, itisa goodidea tousea multiple-output MIDI-THRU boxon each
SL-2001output. The SL-2001can accessup to 64slavedevices,without requiring any repatching ofMIDI cables:

MIDICONFIGURATION

INSIDETHESL-2001
TheSL-2001isvery unique among MIDI keyboards. All ofitspowerful master controller functions are available from itsown
keyboard, or from any external MIDI keyboard. In addition, the SL-2001alsofunctions as a very versatile MIDI switcher,
router, and processor, which eliminates the need for many outboard MIDI devices.
The diagram above depicts the internal structure ofthe instrument. There are four MIDI inputs and four MIDI outputs. Eight
independentMIDI dataprocessors linkthekeyboard andMIDI inputsto theMIDI outputs. Eachprocessor can be pro-
grammed to receive dataonlyfrom a specific region ofthe master keyboard or external keyboards; it istherefore convenient
to refer to the processorsas ZONE 1 through ZONE 8.MIDI information from
two or more zones can be merged (combined) intothesame MIDI output.If desired, all eight zones may be merged into
the same output,althoughtheinherentspeed limitationofthe MIDI formatmay result in sluggish response.The configura-
tion ofthe zones isprogrammable for every preset onthe SL-2001.In general, each zone will be associated with one MIDI
synthesizerconnected totheMIDI outputs.In special cases, several zones will be processing MIDI data which will all be
merged to the same MIDI outputandreceived by a single sound module.
ZONES
TheSL-2001keyboard will sendMIDI data to asmany aseight instruments simultaneously (the instruments may bephysi-
cally separate devices, or different MIDI channels ofa multi-channel sound module). Each instrument receives MIDI data
from one oftheeightzones. The sophisticated MIDI processing performed by the zone allows very precise control over the
sound and response ofeach instrument.The functionofalleight zones isindependently programmable in each ofthe sixty-
four SL-2001presets.
Thediagram above illustrates the internal structure ofa zone. A MIDI message from a SL-2001input port isreceived by all
zones connected to thatinput. Ifthe zone isnot active (front panel ZONE switch isoff),no furtherprocessing occurs. If the
zone isnot bypassed, anincoming message is checked to seethatits channelmatches the channel programmed into the
zone's ChannelFilter.If the channeldoes not match, the zone ignores the message.

Ifthe channel ismatched, the MIDI message continuesthrough the zone. MIDI note messages areprocessed by many mas-
ter control functions,which may modifythe note number,velocity, or perform other sophisticatedprocessing. MIDI con-
trollermessages may be passed unchanged, converted toa different controller message (mapped), or blocked completely.
The resultingMIDI message isthenassigned a specific MIDI channel, delayed (programmable from zero toten seconds),and
routed to one ofthe fourMIDIoutputs.
The zones are able to issue program change and controller initializationvalues (volume, modulation,etc.) atthe instanta SL-
2001 preset isselected. These messages willbe issued even if theZONE switch isoff.If the zone isactivated later with a
footswitch, thesound module willalready be setfortheproper program and controller
settings. Program and controller initialization messagesmay be enabled or disabled as discussedin section8.
When theSL-2001 isused as a general-purpose MIDI switcher, a zone may be bypassed to allow all MIDI data to How from
the zone's inputto its output.The messages retainthesame channel number as received. This mode is usefulforsequencer
applications, where dataon allsixteen MIDI channels is passed as a groupfroma SL-2001 inputto a SL-2001 output,(sys-
•tern-exclusive data is passed ONLY through bypassed zones).None ofthe processingorcontroller initialization functions
are available when a zone isbypassed.
Regardless ofzone mode, all note messages issued to the outputare monitored. Whenever a zone isturned off, note-offmes-
sages are automatically issued to clear any sustained notes.
DEVICENAMES
The SL-2001 offers simplified programming and operation by allowing allMIDI devices in the system to be designated by a
five-charactername. Before any programming begins,these names are entered intothe SL-2001. While entering the device
names, theuser also specifies theMIDI portto which thedevice has been connected (MIDIINA-D or MIDI OUT A-D) and
the MIDI channel(1 through16)on which the device isset. For all subsequent programming,devicesare specified by name
only; the portandchannelare not requiredas they are implied by the name.Forlarge MIDI systems in particular,thismakes
programming muchmore efficientas it relieves the musician ofhavingto remember the port and channel numberfor each
device.
Some synthesizers are multi-timbral, which means that they are able to produce several different sounds simultaneously, such
as strings, organ, andpiano sounds. Each ofthesounds iscontrolled by information on a different MIDI channel. When
used with the SL-2001, a multi-timbralinstrumentshould actuallybe considered as more thanone instrument,and each
should have a uniquename in the SL-2001 device list. For example, if sound module XYZ can produce two sounds inde-
pendently, we can install two devicesinto the SL-2001:XYZ1 and XYZ2.
The SL-2001master keyboard isrepresented by the devicename "2001";this name may not beedited ordeleted. Besure to
consultsection4 toinstall devicenames before you attempt to program the SL-2001.

OPERATION
TheSL-2001front panel isdesigned for fast and efficient programming ofall functions. Learning to operate the unitisvery
easy,asthe large 48-character LCD textdisplay assists by presenting function and parameter names which are usually self-
explanatory. In addition, allMIDI devicesconnected to the SL-2001 are designated by five-character names, which greatly
simplifies programming ofpresets.
The Front Panel diagram identifies the variouscontrols anddisplayareas. There are only two operatingmodes: Perform
Mode and EditMode. The front panel ofthe SL-2001 iscolor-coded to indicate the functionofeach control in Perform (gray
labels) orEdit mode (blue labels).
TheEDIT switch isused to selectbetween Edit and Perform Modes (the red LED on the switch islit in Edit mode). Edit mode
isused to edit an existing SL-2001 preset orto create a new one. While in Edit mode, the SL-2001 isstill active and perform-
ingMIDI dataprocessing (althoughcertain functionsare inhibitedwhichwould interfere wdth theprogramming procedure).
Once thepresets have been programmed as desired, the unitshouldbe switched to Perform Mode. The STORE switch is
used to record an edited SL-2001 program into a specific preset location, or to copy presets from one location to another. The
Storefunction can be usedwhile in either Perform Mode orEdit mode.
Aspecial All-Notes-Off functionhas been provided to clear any notes that become stuck on synthesizers and sound modules
receivingdatafromtheSL-2001. PressingtheEDITandSTOREswitchessimultaneouslywill initiateasequenceofmessages
to the MIDI slave devices which should clear the stucknotes. Using theAll-Notes-Off function will not change the current
SL-2001operation mode.
PERFORM MODE
During performance or recording sessions,the SL-2001will normally remain in Perform Mode. While in Perform Mode, the
textdisplay presentsvery useful information regarding the current preset.
PresetName: A 10-character label entered by the user that describesthe current preset.Presets may beselectedeither from
internal memory or the card memory (ifpresent). Ifthe current presetresidesin the memory card, the preset name will
appear in square brackets [preset name].
Switches: Displays the statusofthethree general-purpose switches (controlled by the back-panel input jacks). Ifa switch is
on,the switch letter (A,B, orC)will appear. Ifthe switch isoff, there will bea dash. Note that these lettersindicate the cur-

rent state ofthe switch, which may not directly correspond to whether the footswitch ispressed.Seesection7 for informa-
tion on programming the switch modes and initialvalues.
Chain: If the chain function isbeing used, the selectedchain (Athrough Z) will appear, followed by the current stepnum-
ber.Ifthe selectedchainhas not been programmed, the stepnumber will not appear.
csl1 - csl4: Labelsselected.bythe user to describethe function ofthe four control sliders in the preset. Thereare a totalof
twenty-four characters in thisline.Thisarea may alternately beusedto display any other general information concerning the
preset.
Preset Digits: There are sixty-four presets in the SL-2001 arranged in eight banksofeight presets. The optional memory card
stores an additional sixty-four presets. Throughout this operation guide, theword preset refers to the storage location ofthe
SL-2001.Theword program refers to a particular sound setting ofan external instrument. Tocallupa new preset, first use
the left or right arrow switches to select the desired bank (if differentfrom the currenthank).The first displaydigit will
change to the new bank,and the second digit will turnoff.Next, use the eight PRESET switches to select the desired preset.
The new preset willbe loaded and the text display will change to reflect the new preset.Ifthe Conditional Preset Change
function (Section 6)is enabled, the SL-2001 preset will changeonly afterallkeys havebeen released from thekeyboard and
the sustain pedal isreleased. The new preset numberwill Hash untilthese conditions are met. If the Conditional functionis
off, any notessounding onthe MIDI soundmodules willbeturned off automatically before the presetischanged.
The SL-2001presets are storedin non-volatile memory circuits powered by a lithium battery when the power isswitchedoff.
After several years ofoperation, the battery will need to bereplaced. A warning messagewill appear onthe LCD display if
the battery voltage istoo low. Contact your dealer for a replacement battery.
The sixty-four memory card programs are stored in eight banks ofeight presets. Thecardprogram banks are storedcon-
secutivelywith the internal banks. Ifyou use the left orright arrow switches to selecta bank number that isgreater than
eight or lessthan one, the SL-2001 will enter the card memory area. When one of the eight PRESET switches ispressed, the
new card preset will be active. Card presets are denoted by square brackets aroundthe preset name in the text display.
When receiving MIDI program change commands, the SL-2001 interpretsprogram change numbers 0 through 63as internal
presets (11through 88),and program change numbers 64 through 127as card presets.
The ZONE switches indicate whether each zone isactive or disabled. These switches may be pressed at any time to enable
or disable a zone. Depending on the configurationofthe preset, several zones may be sending MIDI information to the same
sound module. Toprevent notes from sounding onthis module, itwill be necessary to turnoff all zones associatedwith the
module. Any notesthat are sounding when a zone isdeactivated will beautomatically turned off.
The two switches below the EDIT and STORE switches are the Star (*)and Alpha (a)switches. In Perform Mode, the func-
tion ofthese switchesisfully programmable. They may beusedtoactivate sound modules, send MIDI messages,or other
functions.
EDITMODE
Toedit a preset or create a new one, you must press the EDIT switch to enter Edit Mode (the red LED on the switch will light).
AllSL-2001 functions are arranged into eight groups. The desired group isselectedwith one ofthe eight FUNCTION switches.

Each time the function key ispressed,the text display will present the next function ofthe group. Each function contains
from one to fourparameterswhich may be changed withthe corresponding control slider. Many ofthese parameters have
alarge numberofpossible values.In order to allow easy access, the values are divided into several groups. Adjacentgroups
ofvalues are selectedby moving the slider to the top or bottom end ofits travel. To return to a previous groupofvalues,
reverse the direction ofslider motion.
Whilein Edit Mode, someSL-2001functions are disabled to prevent interference with programming procedures. MIDI con-
trol functionsprogrammed for the fourcontrol sliders or theStar andAlpha switchare activeonly during Perform Mode. SL-
2001 preset changes (from any source) are also inhibited in Edit Mode.
FUNCTIONTYPES
Thereare four categoriesoffunctions in the SL-2001.The categoriesare based onthe programmability ofthe function.
NON-PROGRAMMABLE (functiongroup I): These functionsare not programmable. They are utilityfunctions used to per-
form special operations thatare occasionally needed, such as storing all presets tothe memory card,or displayingMIDI data
entering the SL-2001.When any function in this group isaccessed, the Preset Digits turnoff,indicating thatthe functionis
not associatedwith any particular SL-2001preset.A complete description ofthe utility functions appears insection5.
GLOBAL-PROGRAMMABLE(functiongroup2):Functionsinthis'categoryhaveparametersthataregloballyprogrammable,
which means thatthere isonly one set ofvalues stored in memory. These valuesare not dependent on the preset thatis
selected; they are the same forall presets. All global-programmable parameter values are stored permanentlyin memory,
evenifpower tothe SL-2001isswitchedoff. Any time a Global-programmable parameter ischanged,thenew valueisauto-
matically saved in memory. The new valuewill remain in memory untiledited again. There isno need to use the STORE
switch to save Global settings; anychanges are automatically updated.
The five-character names assigned tothe MIDI devices in the system are examples ofglobal-programmable parameters;there
isonly one setofnames whichremains thesame forall presets. Any time thata Global functionisaccessed, the Preset Digits
turn offto indicate that the function isnot associated with any specific SL-2001 preset. A complete description ofGlobal-pro-
grammable functions appears in section 6.
PRESET-PROGRAMMABLE (functiongroup 3):Thesefunctionscontainparameterswhichcan have differentvaluesforeach
SL-2001preset. Any change in a Preset-programmable function must be stored into a presetlocation with the STOREswitch.
The PresetName isan example ofa Preset-programmable function. A different name may be entered for every SL-2001pre-
set. When any Preset-programmable functionis accessed, the Preset Digits indicate which preset isbeing modified. A com-
plete description ofallPreset-programmablefunctionsappears in section 7.
ZONE-PROGRAMMABLE(functiongroups4through8):Thesefunctionscontainparametersthataredifferentforeachzone
(as well as each preset). This meansthatevery SL-2001 preset contains eight sets ofparameters, one setforeach oftheeight
zones.When editing these functions, you must choosea particular zone within the particular preset. The zone digit(s) will
appearwhenever a zone-programmable functionis selected. Tochange the zone, use the left orright arrow switch.The
Store functionmust be used to save anychanges in zone parameters.
The MIDI delay setting is anexample ofa zone-programmablefunction.For every preset, each oftheeight zones may be
programmed fora differentdelay time (0to 10seconds). A complete description ofall zone-programmable functions appears
in section8.

EDITINGA PRESET
Toedit an existing preset, enter Edit Mode and select the desired edit screen with the appropriateFUNCTION switch. As an
example, we will use the first screen offunction group 4 (ZONE).In thisexample ofan Edit Mode display, there are four
parameters shown. The current value ofeach parameter appears below the parameter name, and may bechanged with the
corresponding control slider (while in Edit Mode, anyMIDI control functionsassigned to a control slider are disabled). The
zone digit ispresent because these functions are zone-programmable (when editing a zone-programmable function, besure
that the correct number isdisplayed or the wrong zone may be inadvertently changed).
There isa Star on the third parameter ofthis screen. The Star isused in several functions to indicate that there isan alter-
nate screen which can be accessed by pressing the Star switch. The alternatescreen contains additional parameters thatare
related to themainscreen butwhich are not always used. Toget back to the main screenpressthe Star switch again. While
in Edit Mode, any MIDI control functions assigned to the Star switch are disabled.
The Alpha switch isalso used in Edit Mode, usuallyto initiatespecial operations like memory load or save. Its functionwill
be designated on the screen where it isused. While in Edit Mode, any MIDI control functions assignedtothe Alpha switch
are disabled.
CREATING NEW PRESETS
Creating an entirely new preset requires three steps: configure the zones, program each zone, and program any desired mis-
cellaneous Preset-programmable functions.The specific details ofzone functionsand miscellaneous preset functionsiscov-
ered in reference sections 7 and 8.Afterlearninghow to create basic presets in thissection, scan sections 7 and 8 to become
familiar with the many powerful functionsavailable, and consult specific explanations as needed. Before any presets are cre-
ated, all devices used in the MIDI system must be designated by a five-character name and entered into the SL-2001's device
list.TheMIDI port and channel associated with eachdeviceisalso entered.
DEVICEINSTALLATION
The DEVICES screenisused to enter the name and description ofall MIDI devicesin the system.This information should
beentered into theSL-2001 before any new presets are created. For every device in thesystem, the SL-2001 must know the
port to which it has been connected and the MIDI channel on which the device istransmitting or receiving. SL-2001 presets
are then easily created by referring to the device name only; the port and channel are implied by the name and need not be
displayed.

INPUTDEVICES
Keyboards, MIDI guitars, drums, orother controllers are inputdevices. As an examplewe will install a MIDI keyboardwhich
has been plugged into inputA ofthe SL-2001. We will assume thatthe keyboard issetto transmiton MIDI channel number
one.While in Edit Mode (red light onEDIT switch ison) accessthe DEVICES screenby pressing function switch2
1.Using Control Slider 2, setthe Port parameter to IN A. Thismeans that the keyboard we are installing isphysically con-
nected to MIDI IN A ofthe SL-2001.
2. Adjust Control Slider 3 untilthe Channel parameter ison1.Thissignifies that the keyboard has beensetto transmit infor-
mation to the SL-2001 on MIDI channel 1.
3.Oncethe Port and Channel are properly set,the devicename can beentered by pressing the Starswitch.

Thedevicename will beentered onthe secondline ofthe text display, starting at the far left end. The flashing "A"indicates
the current position ofthe cursor. Adjust Control Slider1 until the desired character appears. Note that when the slider is
moved to the extreme upperor lower end, a new set ofcharacters isaccessible. Reversing thedirection of slider motion and
moving back to thetop or bottom end will enable access to the previous setofcharacters. The charactersavailable fordevice
names (and presetnames) include the complete alphabet in upper and lower case,numerals 0 through 9,and a variety of
punctuationmarks and special symbols. Thesecharacters may alsobeentered by pressing the appropriate keys onthe SL-
2001 keyboard.
Tochange the position of the cursor, use theleftandrightarrow keys C ).There are a totaloffive characters available
for the name. When the name has been completely entered, press theStar switch to returnto the main screen. The screen
will now display the name asitwas just entered, along with the port and channel number.
Toinstall a second device (for example, anotherkeyboard on MIDI IN B) adjustthe port and channelvalues as necessary,
press the Star switch,and enter the name ofthe new keyboard. The SL-2001 local keyboard isdesignated by the device name
"2001";this name may not beeditedor deleted. Additional keyboards in your systemmay beconveniently named Kybd2,
Kybd3, oryou may choosetouse the model name or number.
OUTPUTDEVICES
Synthesizers, sound modules, percussion modules, and other sound generators are output devices.Installation ofthese
devices follows the same procedure, except thatadditionalinformationmust be entered to describe thedevice. As an exam-
ple, we will install a MIDI sound module on MIDI OUT A, channel1.Adjustthe port and channel valuesas necessary and
press the Starswitch to accessthe alternate screen.
As before, the 5-character devicename isentered using Control Slider 1 to selectthe character and the arrow switchesto
move the cursor position (characters may also be selected by pressing the appropriate keys on the SL-2001keyboard).
Because we are installing an output device (MIDI OUT A was selectedas the port) there are two additional parameters that
must be set.
The Prg (program) parameterhas two values: Zone and Auxiliary. For synthesizers or any other sound generators, this para-
meter should be setforZone. This means thateach sound module receives MIDI program change commands fromthe asso-
ciated zone that controlsit.
AUXILIARY DEVICES
SomeMIDI devices (such as audio effects units or programmable EQ units) do not require MIDI note orcontroller informa-
tion, they needonly to receivea MIDI program change command. Forthistype ofauxiliary device,there isno needtoded-

icatean entire zone just to sendprogram change commands. The SL-2001has the ability to send simple MIDI program
change commands to eight auxiliarydevices. Selecting theAux option (csl 2) identifies the MIDI device as an auxiliaryunit
which will receive MIDI program change commands independently ofthe zones (although a zone may still be assigned to
an Aux deviceifdesired). The eight devices designated as auxiliary units will appear on the AUX PROG screen, where the
desired program change values may beentered (seesection7 for furtherinformation).
The Format parameter refers tothe arrangement ofpresetsonthe MIDI device being installed. There are four preset formats
in common use:MIDI, MIDI+1, Bank, and Alpha.
MIDI: Presets on the instrument are numbered starting with program 0 (zero)and increaseby singlesteps.Example: 0,1,2,
3,4, 5,6,7,8,9,10,11,12,etc.
MIDI+1: Presetsonthe instrument are numbered starting with program 1 and increase by single steps.Example: 1,2, 3,4,
5,6,7,8,9,10,11,12,etc.
Bank: Presetsare arranged in banks, with eight presetsper bank. The first digit ofthe preset specifies the bank, and the sec-
ond digit specifies the preset within the bank (this isthe format usedon the SL-2001). Example: 11,12,13,14,15,16,17,18,
21, 22, etc.
Alpha: Presetsare designated by a letter plus a number from one to eight. Example: Al,A2, A3,A4, A5, A6, A7,A8,Bl, B2,
etc.
Bysettingthe Format parameter to match the instrument being installed, the SL-2001will beable to display program change
settings on the edit screens in the proper format. Thisgreatly simplifies programming ofpresets; ifyou know that a particu-
lar string preset on a synthesizer is in bank 2 preset number 1,you do not need to know that this isactually equivalent to
MIDI program change command 8.
Afterthe device namehas been entered andtheprogramandformatparametershave been set, press the Starswitchto return
to the main screen. The new devicewillnow be displayed with the port and channel as programmed.
Repeat the installationprocedureforall devices in the system. If you havea multi-timbralsound module,each channel of
the instrumentmust be installed as a separate device. As an example, ifsound module XYZ can play two sounds at once,
install deviceXYZ1 andXYZ2 into the SL-2001 devicelist.
Once all deviceshave beeninstalled, itispossibleto reviewthe listofdevices at any time. The first three controlslidersare
allactive onthe main screen. Moving Control Slider 1 scrolls through the listofall devicenames. The port and channel will
change to match thevalueschosen when the device was installed. Moving the port (orchannel) sliderwill likewisecause
the device name to change accordingly.
NOTE: To change the port and channel for a device after it has been installed, it is necessary' to delete the device (using the
Alpha switch} and re-install it. Clanging the name, Prg parameter or Format parameter/or a device dues not require dele-
tion. Select the device on the main screen, then press the Star switch to access the alternate screen for editing.
ZONE CONFIGURATION
Thefirst stepin creating an entirely new SL-2001preset isthe configuration ofthe zones. Each zone functions asa link
between the keyboard andan outputdevice (asound module). For each zone thatwillbe used in the preset, the inputand
outputmustbe assigned to the desired devices. EnterEdit Mode andpress FUNCTION switch 4 to access the ZONE screen.
The zone digit will display the number ofthe zone to be edited, and may be changed with the left and right arrow switches.
In normal operation, a zone receives MIDI data on only one specific channel, processesthe data, and sendsthe data toa SL-
2001 output ona single MIDI channel. The source and destination for the zone are selected by choosinga devicename from
the SL-2001devicelist.The actual SL-2001port and channel number need notbespecified, as they are implied by the device
name,
Multiple zones can be assigned in any combinationto theSL-2001 keyboard or external keyboards. Up toeight sounds may
be controlled simultaneously, each with fullyindependent key range, dynamics,transpose, etc.

The example screen above shows Zone 1 configured to pass MIDI information from a keyboard (Kybd2) to a sound mod-
ule (Mod#3). Tochange thezone's inputassignment, move Control Slider1 until the desireddevice name appears. To
change the zone destination, move control slider number2.
Azone may be programmed to operate only in a specific region ofthe master or external keyboard. Use Control Slider 3 to
setthe lowest desired note, and Control Slider 4 to select the highest note desired. This range may also be programmed by
selectingthe noteson the keyboard for that zone. Press the Starswitchtoaccessthe alternate screen.
Press the two keys that correspond to the highest and lowest notes desired for the zone. You must play these notes on the
instrument specified on the screen. After thesecond note ispressed, the display will automatically revert to the main ZONE
screenwith the new settingsas programmed. -.
For the majority ofpresets,onezone will be used for each MIDI sound module in the system.Toaidin programming and
modifyingpresets, try to always assign zones to sound modules in the same order. Any remaining zones are free tobeused
for special applications and effects, for example, MIDI echo.
After assigning the zone inputs and outputs,the zone must be enabled with the front-panelZONE switch. The green light
indicates thatthezone isactive. Note that at least one zone must beactive in every SL-2001 preset, otherwise MIDI data can
not pass fromthe inputsto the outputs.

Many specialeffects can becreated by using multiple zones tocontrol a single instrument. Tocreate an echo effect, use two
zones assigned to the same inputandoutputdevices. The first zone will havedelaysetto zero, while the second zone isset
for the desired delay time. To create multipleechoes, use several zones, each setfora longer delay thanthe one before it.
Decaying echoesmay be produced by adjusting the velocity scaling and offset ofeach zone.
ZONEBYPASS
For someapplications (especiallywith a sequencer) itisuseful to bypass a zone sothat all MIDI data onall channels ispassed
from an input toan output.
Use Control Slider 1 to selectthe desired input (IN A through IN D).By selecting an input port instead ofa devicename, the
zone isautomatically bypassed, and will pass MIDI data onall sixteenchannels. Control Slider 2 isused to selectthe desti-
nation.Notice thatwhen MIDI inputA throughD isselected on Control Slider 1,the normal output devicesdo not appear
on Control Slider 2. This isbecause the outputdevice names represent one specific
MIDI channel, whereas a bypassed zone passes MIDI data onALL channels. MIDI processingfunctions (including the note
range) are not available for bypassed zones and their parameters will not bedisplayed.
ZONE PROGRAMMING
Once the zones have been configuredandenabled,the SL-2001 functionsas a programmableMIDI patchbay. MIDI mes-
sages from the master keyboard or external keyboards may be routedto multiple sound modules underfullprogrammable
control. The next step istoprogram the many zone functions which make the SL-2001a very powerful master keyboard.
The Program, Volume, and Transpose functions are fundamental toevery SL-2001preset. They permit initialization ofthe
program number, volume level,and transpose interval for each sound module usedin the preset.Toaccessthese functions,
use FUNCTION switch 5,6, or7.Refer to section 8 for a detailedexplanation ofthesefunctions.

Thefollowing additional functions are availablefor each zone (refer tosection8 for details):
ZONE CTLSelectsa footswitch or panel switch that will turn the zone onor off.
DELAY Thedata passing through a zone may bedelayed from 0 to10seconds.
VELOCITY Modifies the velocity value ofnote events.
NOTES Selectsthe note-assignment mode ofthe zone.
VOLUME CTLAssignsa slider, wheel, orvoltage input to control the volume ofthe sound module.
KEY HOLD Creates a Sostenuto effect for the zone.
CHORD Adds upto three additional notes to each note receivedby the zone.
CONTROLS Programs wheels, sliders,key pressure (ifsoequipped), voltage inputs, and panel switchesto issue
any desired MIDI control change message.
MIDI ccPrograms the zone to filter, scale,ormap external MIDI continuous controller messages.
MIDI swPrograms the zone to filter, scale, ormap external MIDI switchmessages.
When creatingnew presets, itis possible to copy allofthe parametersfromone zone to another.The new zone can be quick-
ly edited withouthavingtoinitializemanyfunctions.See the section below entitled Storing Presets.
MISCELLANEOUS PRESET FUNCTIONS
The finalstep in creating a new SL-2001preset istoprogram any miscellaneous Preset-programmable functions that are need-
ed.Refer to section 7 for complete information on these functions:
AUX PROG: Sendsprogram changes to effects units, mixers, or other devices.Up to eight auxiliary program
change commands may beissuedper SL-2001preset (this isin addition to the eight program
changes issuedby the zones).
SWITCHES:Setsthe initial state and response ofthe 3 SL-2001programmable switches (swA, B, C).
PRESET: Programs the alphanumeric names for the preset and sliders.
Before storing the preset, make sure thatall zone enableswitches are set as desired.When the preset isselected later,zones
will be enabled or disabled according to the state ofthe ZONEswitches whenthe preset was stored (seesection 8 under
"ZONE Control").

STORING PRESETS
Once you have finished creating or editing a preset, it must be stored into one ofthe SL-2001'ssixty-four memory locations
(128with memory card). While still in EDIT mode, press the STORE switch.
Thedisplaynow indicatesthat you are ready to storethe editedpreset into a memory location.
Tostore thepreset into its original location (24 in thisexample) press the Alpha switch. You will be prompted to pressthe
Alpha switch again to complete the store operation. Tocancel the operation, press the Star switch.
If you wish to store theedited preset intoa differentlocation,use the PRESET switches and the left or right arrow switches
to select a differentdestination. This new preset will be temporarily loaded sothatyou may be sure thatitisan undesired
preset. Tostore the preset intothe memory card, adjustControl Slider 3 untilthe display reads Store Edit to Card. Press the
Alpha switch as before to proceed with the store operation. When the storeoperation iscomplete, the SL-2001will auto-
matically switch to Perform Mode.
The Store functionmay also beused to copypresetsinto different locations while in Perform Mode. Operation isthe same
as when storing an edit.
It isalso possible to copy allparameters from one zone to another.While in Edit Mode, press and hold the ZONE switch you
wish to copy from. Then press the STORE switch. Release both switches. Afterbeing prompted by a screen message, press
the ZONE switch ofthe destination. After completing the copy operation, the SL-2001 will returnto Edit Mode.
Astore operation may beaborted at any time by pressing the STOREswitch.TheSL-2001willrevert back to Edit Mode or
Perform Mode.
INITIALIZATION
Like any computerequipment,the SL-2001 may be adversely affected by low or noisy line voltage, high electrostatic fields,
or other environmentalhazards.Under extreme conditions,the unit'sinternalmemory may be disturbed,resultingin erratic
operation. It isthen necessary to re-initializethe memory to restore correct operation. This operation clears ALL presets and
global data,thereforeSL-2001 presets should always be saved on a memory card orviasystem-exclusivetransfers. After the
memory iscleared, the data can be reloaded into the SL-2001.
To initializememory andclear alldata. enteredit mode and select theMEMORY USED functionby pressing functionswitch
1twice. Adjust control slider 4 untilthe displayreads Erase All. Press the Alpha switch to start the operation. When the clear
operation iscomplete, the SL-2001 memory may be reloaded from a memory card or via MIDI system-exclusive data. Consult
Section5 for information on memory transfers.
