Pressing either button, the instrument automatically plays a reference
noteCwithanintensitycorrespondingtothecurrentvelocitysetting. In
this case, the current setting is NORMAL (default) and the reference
note C will play with a medium intensity.
2. Ifyou press theDATAmbuttona secondtime,youwill selecttheSOFT
velocity curve, identified by the reference note C which will play with a
greaterintensity.
The SOFT setting corresponds to the most sensitive keyboard re-
sponse which permits maximum sound levels with a light touch.

About MIDI
MIDI, the abbreviation for “Musical Instrument Digital Interface”, is a world
standard interface that allows MIDI compatible instruments and other equip-
ment to communicate with each other, in order to exchange data and control
oneanother. MIDIisnowaverycommonfeatureandagreatdealofliterature
is available explaining all the standards implemented by MIDI. You are
recommendedtoconsultotherspecializedliteratureifyouwishtoknowmore
about the standards implemented and how to apply them. This section limits
itselftogivesomeexamplesregardingthesimplestformsofMIDIapplications
for your RP60/70.
The MIDI ports
The RP60/70 is fitted with two MIDI ports: MIDI IN and MIDI OUT.
The MIDI IN port receives MIDI data from an external MIDI device which can
be used to control the RP60/70.
The MIDI OUT port transmits MIDI data generated by the RP60/70 (for
example, note or velocity data generated by playing the keyboard).
MIDI channels
The “MIDI channels” used in the MIDI communication system is similar to
television broadcasting. Each channel can receive a different stream of data
withrespecttotheothers. Exactlyasoccursintelevisionbroadcasts,inorder
to exchange data, the receiving and transmitting devices must be tuned
correctly. In other words, the MIDI controlling device and the MIDI receiving
devicemust both beset to thesame MIDI channel,selected from16possible
channels.
Multiple channel instruments, called multi-timbral units, can receive and
transmitacrossseveraldifferentMIDIchannelsatthesametime,buteachpart
must correspond to the same MIDI channel between the two communicating
units. RP60/70isabletotransmitonuptothreeMIDIchannels. In reception,
RP60/70 can be used as a multi-timbral unit, because it can receive MIDI on
16 channels.
Midi Common
If you set RP60/70 to receive MIDI messages on the Common channel, all
program change messages received by RP60/70 are interpreted as Preset
Change messages, allowing you to play the 16 Presets from the external
keyboard which emulates the RP60/70 internal keyboard. Simply set the
externalcontrollingdevicetotransmitMIDImessagesonthesamechannelas
the RP60/70 Common channel.
The RP60/70 MIDI Sounds and Banks
Via MIDI, your RP60/70 offers some interesting features which cannot be
achieved using the instrument on its own. On its own, the maximum number
ofPresetsyoucanselectonRP60/70arethoselistedonpage4,atotalof16,
some of which recall single sounds, some two layered sounds across the
keyboard and others two or three sounds on a split keyboard.
WhenyouuseRP60/70asaslavedevice,aMIDIcontrollerkeyboardcanplay
the RP60/70 internal Midi sounds which are organized in four banks, the first
three housing 128 sounds organized in “family” groups, and the fourth
containing60sounds. Thebank1soundscorrespondtotheindustrystandard
General MIDI sound library, while banks 2 and 3 contain sounds taken from
Generalmusic’s own extensive sound library. Bank 4 contains an additional
60 Sounds, but not organized i “family” Groups like those in banks 1, 2 & 3.
Banks 2 and 3 also contain a Percussive family where you’ll find a selection

14
of 16 Drumkits. Another drumkit is also in Bank 4.
These sounds and sound banks can only be selected via MIDI, not from the
RP60/70 control panel. To select these sounds via MIDI, you would have to
sendaMidimessagetotheRP60/70 consistingof twoparts: ControlChange/
BankSelect(CC00-BankSelect)followedbyaProgram Change (PC). Refer
to the Midi sound tables in the Appendix for information regarding the Banks
and Program Change numbers of all the sounds and Drumkits.
MIDI messages transmitted and received by RP60/70
RP60/70 transmits and receives the following type of MIDI information.
NoteandVelocitydata:Thisisinformationpertainingtothenoteplayedand
relativevelocityvalue. Thereceivingdevicerecognizesthenotebecauseitis
defined by the “MIDI note number”, and the velocity value is defined by the
“MIDIvelocityvalue”. WheneverakeyontheRP60/70ispressed,thenoteand
velocityinformation istransmitted from the instrument’s MIDI OUT portto the
receiving device. Conversely, RP60/70 will play the corresponding notes
whenever note and velocity data is received at the instrument’s MIDI IN port.
Program Change numbers: This type of information relates to data which
identifies the RP60/70 Preset. RP60/70 transmits MIDI Program Change
numbersfrom1-32,correspondingtothe32Presetsthatcanbeselectedfrom
the panel. Whenever you select a Preset, the corresponding MIDI Program
Change number is transmitted to the receiving device, causing the corre-
spondingly numbered voices to be selected in the external MIDI unit, set to
receive on the same MIDI channel as the RP60/70.
Conversely, whenever RP60/70 receives Program Change number data (for
1-32) from an external MIDI device, the correspondingly numberedRP60/70
Preset will be automatically selected, but only if received on the Common
channel, otherwise, the internal Midi Sounds will be selected.
Control Change messages: The Soft and Damper pedals of RP60/70

RP60/70 Sound engine. Whenever the same type of Control Change data is
received by RP60/70, it will respond appropriately.

MIDI Applications
The following explains how your RP60/70 can be used in the most common
MIDI setups suited to this instrument:
a) as a MIDI controlling device (Master);
b) as a tone generator (in other words, a Slave);
c) for MIDI sequence recording.
As a MIDI controlling device
RP60/70, like most MIDI instruments, transmits note and
velocity information (touch response) via the MIDI OUT port
whenever notes are played on the keyboard.
IftheMIDIOUTportisconnectedtotheMIDIINportofanother
MIDI keyboard (synthesizer, etc.) or a tone generator (more
commonly called an “expander”, but essentially any device
with an internal sound engine), the external unit will respond
precisely to the notes played on the transmitting keyboard.
Theresult is thatsucha setupallowsyou toplaytwo instruments atthe same
time, using RP60/70 as the controlling device (Master) and the other as the
device being controlled (Slave).
Quite simply, every time you select a Preset, you will send Program change
messagestotheexternaldevicewhowillrespondbyplayingasecondsound.
As a Slave device
Aswell astransmittingMIDIinformation,RP60/70recognizes
the same type of data if received at the MIDI IN port from an
externalcontrollingdevice. Inthiscase,theMIDIINportofthe
RP60/70 is connected to the MIDI OUT port of the external
controllingunit. This,therefore,allowsRP60/70 tobecontrol-
led in exactly the same manner as described above, only this
time, the RP60/70 behaves as the slave and the external
device the controller.
Midi Sequencer recording
Thetypeofdatatransferdescribedabove can be exploitedvery
efficiently for MIDI sequence recording. For this connection,
showninthediagram,theRP60/70MIDIOUTisconnectedtothe
SequencerMIDIIN,andtheSequencerMIDIOUTisconnected
to the RP60/70 MIDI IN. This connection is more commonly
know as a “MIDI Loop”.
Any instrument with a sequencer, or a Computer running
sequencer software, can be used to capture (record) the MIDI
data transmitted by the RP60/70.

Panel Reset
RP60/70offersaPanelReset function which allowsyoutorestorethefactory
settings without turning the instrument off.
For example, if you have changed some parameters, such as the MIDI
channels, the tuning, the velocity curves, etc., you can restore the factory
(default) settings with the following procedure:
