In addition to the "IMPORTANT SAFETY INSTRUCTIONS" on the previous page please note the
following:
Important Notes
Connecting to the Mains:
- Do not connect the unit to a socket which is already feeding other units that can cause
interference (for instance electric motors, light controls, fridges etc.)
- The heat generated by the mains adaptor is completely normal.
- Whenever you intend to connect the Sirius to other units, first turn off all units. This will prevent
possible malfunctions and damage to speakers and other equipment.
Installation:
- Using the unit close to heavy power sources (or other units containing larger mains transformers)
can cause "humming" or other electrical interference.
- The unit might cause disturbances to television and radio. Do not set up your unit near any of
these receivers.
- Do not expose the unit to extreme temperatures (like for instance direct sun light in a closed
vehicle or extreme frost in winter). The unit could be damaged or the varnish on the casing might
disintegrate.
Maintenance:
- To clean the unit wipe it with a soft, dry or damp cloth. To remove persistent stains you can use a
damp cloth and a neutral cleaning agent. Wipe the unit dry afterwards.
- Never use Petrol, Thinner, Alcohol or similar cleaning agents to clean your unit. These can
dissolve the markings and varnish and might deface the casing.
Repairs and Data:
- Please remember that you might lose the memory of your unit when you send it in for repair.
Important information should therefore be stored on a different MIDI-unit (for instance
Sequencer). Although every care is taken when repairing your unit it can happen, especially when
work to the storage/memory or affiliated groups is necessary, that information is lost. Please note
that it is not possible for us to restore lost data.

Important Notes
See page 52

Storage Protection:
- The memory of the unit is secured with a Lithium battery (CR 2025). The storage contents will
remain even when the unit is switched off. Depending on how it is treated, the battery will last for
several years. Should you have to exchange it, please contact our Service-Department. Please
make sure that the old batteries are disposed of properly. Batteries of all kinds do not belong in the
domestic trash, as they contain dangerous heavy metals.
Additional precautions:
- Please consider that the storage contents can also be irrevocably lost through mal-function or
improper use. Important data should therefore be stored regularly on another MIDI-unit (for
instance a sequencer)
- For these cases we point out that it is not possible to restore lost data.
- Treat the keys and dials as well as the connection sockets with care - improper use can lead to
mal-functions.
- Never press or hit the buttons or the display hard.
- Whenever you are connecting or disconnecting cables, always pull the plug itself, do not pull the
cable. This will avoid short-circuits and cable damage.
- Should you wish to transport the unit, it is best to use the original carton (including the
polystyrene inlays)
The CE-Sign on our products declares that our electrical devices are in
conformity with the EN 55014 and EN 50082-1 (in accordance with 89/336

Introduction
Congratulations on your purchase of the QUASIMIDI POLYMORPH. You can be sure that you
have acquired one of the most modern electronic music instruments with many innovative
features. By integrating the Morphing Sequencers with the expressive synthesizer engine, you have
the ability to easily create sounds which most other synthesizers would find difficult if not
impossible to copy.
The POLYMORPH is a sophisticated instrument with many complex features and facilities which
are described in full in this manual. To get started, we recommend you read the Basics section
first to familiarize yourself with the layout, controls and fundamentals of operation.
Basics
Conventions used in this manual
The POLYMORPH has numerous keys, which control various functions of the synthesizer. All of
the keys have fixed names which will be shown in square brackets in this manual. Whenever we
refer to a sequence of button pushes it will look something like this:
e.g. Push [BUTTON 1] followed by [BUTTON 2]
In the manual we have simplified statements such as: Push the Start / stop button, with Push
[START/STOP]
To simply distinguish between pushbuttons and rotary knobs in this manual, we have used angled
brackets for the rotary knobs:
e.g. Turn the <CONTROL KNOB> completely to the left
instead of EXAMPLE in the pointed brackets the button description will be shown.
Other logical abbreviations will also be used for simplicity and convenience.
e.g. Turn the <LOW PASS CUTOFF> completely to the left, rather than explicitly stating turn the
"knob labeled <CUTOFF> in the low-pass filter section..." etc.
For better orientation you will find the following little helpers in this manual:
This symbol marks the useful tips given in
this manual.
This marks text passages to which you
should pay special attention.

!

Installation and Audio Connections
The box in which the POLYMORPH is packaged is ideal for transportation. It is secured by
molded-polystyrene supports. One of these also holds the power supply adaptor in a small box.
We recommend that you keep the box and polystyrene for future use, in case you want to
transport the POLYMORPH for instance, or if you send it to QUASIMIDI for a software version
update, it must be in the original packing.
The following parts should be contained:
1 POLYPMORPH
1 stereo ( or two mono) audio cable with phono / RCA plugs and jack adaptors
1 power adaptor
1 owners manual
1 warranty form
After unpacking, the POLYMORPH
should be placed on a stable surface
and the power adaptor can be
plugged into the Power Input socket
at the back panel of the
POLYMORPH. The main plug can go
into a wall socket, but you should
ideally make all audio and MIDI
connections first before turning it on.
To listen to the POLYMORPH you
can either plug in headphones to the
top panel, or connect its stereo audio
outputs into a amplification system
such as a keyboard combo amp or a
hi-fi system, or run it through a mixing
desk or outboard processors such as an instrument preamplifier, compressor or equaliser before
injecting it into your signal chain if you prefer. We have supplied suitable audio cables for
connections. The POLYMORPH's main output is stereo, unbalanced and has a nominal line level
of around -10dBV. It also has two more additional audio outputs which you may also want to use
as well, but they are not necessary to begin with. They would be treated the same way as the main
stereo outputs.
Connecting the POLYMORPH to a mixing desk
The POLYMORPH's audio outputs are at line level and should require hardly any gain through the
mixer input stages. it is best to make connections with all the equipment switched off in case there
is any electrical fault, but if it is on, the mixer's channel faders that you are going to use for the
POLYMORPH input must be turned down or muted to prevent any electrical burst noises going
through to the outputs. These switch-on transients and plugging-in pops can cause severe damage
to loudspeakers, headphones and your ears, and will easily overload most equipment. Check that
8
Basics
power supply
Tip

not only are the relevant channel faders muted, but also any aux sends, effects sends, direct outs,
inserts, or bus routing switches on these channels as they too can pass the dangerous noises on
from that channel's input to their destinations.
Pressing the [START/STOP] button on the POLYMORPH will begin a drum pattern, which you can
use as a test signal. Start with the <MAIN VOLUME> knob low and gradually bring it up to a
reasonable level.
If your mixer has a gain pot, start at the lowest setting, bring the faders up to unity and gradually
increase the gain pot until you get a healthy signal level, checking that it is not distorting anywhere
along the signal path. If you have a mixer with a Line/Phono input switch, such as many DJ
turntable mixing desks, then select the Line input. (The phono input is for low level turntable
cartridges only and will be severely overloaded by the high level output of the POLYMORPH.)
If you have stereo inputs on your mixer, the left/right balance knob should be set to the centre
position. If you use two separate input channels, then the panpot for POLYMORPH channel 1
should be panned to the left and POLYMORPH channel 2 should be panned to the right.
Connecting the POLYMORPH to a hi-fi system or portable stereo etc.
From the point of view of connections, the POLYMORPH can be treated as if it were another CD
player. Its output will be a similarly high line level and require a similar high impedance audio
input stage such as any labelled LINE, AUX, TAPE, CD, DAT which usually have RCA/phono plugs
and hence will fit the cables supplied by QUASIMIDI with your POLYMORPH. However, you
should never use the record player / MC / MM / PHONO input because the high level output of
the POLYMORPH will overload it.
(If the only available input is something else such as a 5-pin DIN plug, or two XLR inputs then you
will need to purchase the appropriate adaptor or cable for your application.)
Make sure that the volumes are turned fully off before plugging in and powering up, preferably the
hi-fi amplifier should be the last component to switch on, and the first to switch off. Press the
[START/STOP] button on the POLYMORPH to begin a drum pattern to listen to, and starting with
the volumes at low levels, gradually increase them to a comfortable level. If your portable stereo
has a "Loudness" button or some kind of "Hyper / Mega Bass Boost" button it is probably best to
turn it off at first unless you are listening at low volumes because the POLYMORPH has resonant
filters that can tune down to very low / subsonic frequencies that may easily distort with these
processes applied, and this could damage your speakers etc

Connecting the POLYMORPH to a Keyboard Combo Amplifier
Some keyboard amplifiers will also have microphone inputs, on jacks or XLRs and these are NOT
suitable for the POLYMORPH as their input impedance is too low (overtaxing the POLYMORPH's
output stage) while their gain range is too high, and they will be overloaded.
Use only the Line inputs, which are sometimes labelled "Keyboard Inputs". If your keyboard
combo is stereo, then connect POLYMORPH's channel 1 to the Left and Channel 2 to the right
input. Switch the amp on last, and start off with the volumes low until you have optimised the
settings such as treble / mid / bass etc. The POLYMORPH will playback some drum patterns if you
press the [START/STOP] button.
If you have to plug into a guitar combo, use a clean channel, high impedance input and start with
the <MASTER VOLUME> knob very low and the amp's input gain should not be turned up too
much.
Trying Out The Setups (Factory Presets)
When first switched on, the POLYMORPH defaults to its "SETUP" operation mode. A setup is the
overall status of all the main controls and adjustable parameters, for the whole POLYMORPH synth
at a given moment, and all this information may be stored in the memory. The global System
Menu however, is not affected by the Setup modes.
In this way, the sound programming of the four parts, the four sequences, all effect settings, and
the tempo adjustments can be recalled instantly from a Setup memory.
Ultimately, each Setup is like a performance patch for the whole synthesizer and determines the
complete function of the four synth engines. The POLYMORPH's four synthesis engines make it
four part multitimbral, and it has 16 voice polyphony and dynamic voice allocation. By turning the
<SOUND> knob, you can scroll through different Setups, which will let you hear some of the
different patches by pressing [START/STOP] to hear some of the preset drum loops / sequences etc.
Now is a good time to play around and listen to these, and hear for yourself the type of effects and
grooves the POLYMORPH is built for. Later on in the manual we will explain how to control the
four synth engines, and how program and save your own sounds and sequences.
Playing of the single sounds from a MIDI keyboard
On its own, the POLYMORPH is a groovey drum machine, but to play melodies or basslines live
you would need to give it MIDI data from a realtime controller such as a master keyboard, another
synth, a digital piano or a MIDI guitar or wind controller etc. Alternatively you can connect it
directly to a MIDI sequencer, either stand alone or computer based, to play back programmed
tracks.
Connect the MIDI output (MIDI OUT) of the master keyboard controller or sequencer to the MIDI
input (MIDI IN) of the POLYMORPH. In this chapter, we will assume you are simply transmitting
on MIDI channel 1, so you would need to verify this on your controller keyboard or sequencer etc.
10
Basics
!

When it receives MIDI messages, the [SEL1] button in the mixer section of the POLYMORPH
should flicker, and obviously you would also hear the sounds you are playing.
Choosing Sounds
Directly after turning the POLYMORPH on it is in the "SETUP" mode. If you turn the <SOUND>
dial in this mode, not only the sound of the chosen parts will be changed, but also the sound of all
4 parts and the assigned sequencer memories. The display would show:
Setupxx:xxxxxxxx
[Sound-Sel][---]
...instead of the "xx" the number and name of the chosen setup will be displayed. To change only
the sounds within the current setup, push [SOUND]. Then the following display message will
appear:
A001: EXAMPLE
[Bank-up][Setup]
This mode selects the single sounds from the different memory banks of the POLYMORPH.
With the softkey [F1] under the display, you can select the memory banks for the sound you wish
to call up. In the banks A-D you have the single sounds which are used in the setups. Those
intended for use as single sounds and especially pre-programmed for solo performance are the
sounds in bank "U". Select this bank by repeatedly pushing [F1]. Now you can recall up the desired
sound to play by scrolling the <SOUND> dial.
With [F2] you can return to the setup mode.

<SOUND> - SOUND / SETUP SELECTIONS
This dial is for the selection of sounds or to call up complete setups. After turning on the
POLYMORPH is in the "setup" mode. A setup can be thought as a complete memory copy of the
preset settings. All parameters are saved in setups except system menus. This mode is confirmed on
the top left side of the display. "Setupxx:" is always displayed in the setup operation. When you
want to change one of the sounds, push [F1] and the POLYMORPH will go into the mode for
changing the single sound. Using [SEL. 1-4] you select the desired synth to change and with
<SOUND> you search for the desired sound. In addition you can change the sound banks with
[F1].
[START/STOP] – STARTING AND STOPPING THE SEQUENCER
With this button you can start and stop the sequences. If the sequencer does not start, check to see

The POLYMORPH mixer section is used to adjust the volume ratio between the single synthesizer
parts. In addition, it contro0ls the selection of one of the four synthesizers [SEL-1] – [SEL-4] or
assigns the sequencer tracks.
[MIX-VOL-1] – [MIX-VOL-4] – VOLUME CONTROL
With these you can control the volume of each synthesizer engine respectively.
[SEL-1] – [SEL-4] – PART SELECTION BUTTONS
Here you can select one of the four synthesizers and one of the four sequencers that you would
like to edit. At the same time the button lights are used as a monitor. When they blink, parts are
receiving MIDI note information. If you can't hear a sound change, you have probably selected the
wrong part. You can find out quickly with the monitor, which part has been selected for editing.
Select the part that blinks while playing. In addition, parts can also be controlled by the morphing
sequencers. While holding down [SEQUENCE-SELECT] you can turn the sequences 1-4 on or off
by pressing the corresponding [SEL1-4]. The current activation state of the four sequencers is
displayed through the button lights. (If the sequence is not active, the notes are not output via
MIDI either.)
MODE – CHANGE
The following four buttons decide how the synthesizer parts will be played.
[UNISON]
In this operating mode the sounds of synthesizer part 1 are laid fourfold over another. Use this
mode for fat and floating synthesizer sounds. In this operation mode the POLYMORPH will only
receive on one MIDI channel. In addition, only the first of the four sequencers is active in this
operation mode.
[ROTATE]
Also in this operation mode all four synthesizer parts are controlled from one channel, or to be
precise controlled only from the first of the four sequencers. This time the different sounds of each
part remain. The four parts do not sound simultaneously. Rather they are driven one after another.
The first note plays part 1, the second note part 2 and etc. At the fifth note it starts from the
beginning with part 1. In this operation mode it's easy to create wave sequences.
[MULTI]
This operation mode is the simplest, and at the same time the most popular way to drive the parts.
All four parts are independent from each other and can be driven on 4 MIDI channels. The specific
MIDI channels can be set in the system menu of the POLYMORPH. The first part reacts on the
MIDI channel that is set as master channel in the system menu. Parts 2-4 lay behind with a rising
MIDI channel number.
[STACK]
In the stack operation mode all four synthesizer parts will be driven with the master channel or
with the first sequencer. In this mode every part plays a different sound. This is suitable for big
layers. eg. You can combine a percussive sound with a soft pad sound and turn off the other two
parts. Turning off parts is done as follows:
1.) Press [EDIT]
2.) Press [F2]
3.) Select menu page 13 with [PAGE<>].
4.) Select the part you want to mute with [SEL1-4].
5.) Use <VALUE> to mute the part.
OSCILLATORS – WAVEFORM GENERATORS
The oscillators create the actual waveforms at the appropriate audio frequency that the synthesizer
sound is based on. The different tone characteristics depend on the waveform shape and on the
subsequent signal path of the POLYMORPH. They can be widely altered.
14
Basics
Tip
Tip

Oscillator-Section
<WAVE1>, <WAVE2>, <WAVE3> - WAVE FORM SELECTION
With these controls the waveforms of the oscillators are selected.
<TUNE> - TUNING
With these controls the pitch of the oscillators is adjusted. <TUNE> controls the basic pitch of all
oscillators into octave lengths with oscillator 1 being the reference, while oscillator 2 and 3 can be
de-tuned independently from each other up to 2 octaves from each other against oscillator 1
<ENV-MOD> PITCH – ENVELOPE - SENSITIVITY
With this control the pitch of the three oscillators can be modulated by an envelope.
When the control is in the middle position there is no sound change, turning to left creates a droop
in pitch and to the right a rise in pitch. (The envelope is found in the edit–osc–menu.)
If the [SYNC] is activated the pitch envelope effects only an auxiliary oscillator, which is synced
with oscillator 1.
[SYNC] - OSCILLATOR-SYNCHRONIZATION
This button starts the oscillator synchronization operation of oscillator 1. It will be synchronized
with an additional auxiliary oscillator. The pitch of the auxiliary oscillator is controlled with
<WAVE-1> when this Sync operation is active. This has the advantage that in Sync operation the
basic sound is controlled with <WAVE-1>. In addition the oscillators 2 and 3 are still independent
from the sync operation and are at your disposal.
<LEVEL1-3> - LEVELS 1-3
These controls set the volume of each oscillator independently from one another. When <LEVEL
3> is turned completely to the left, the 3rd oscillator is turned off and the POLYMORPH's
polyphony is doubled from 8 to 16 voices.

The POLYMORPH has two filters working independently from another, to influence the sound of
the oscillators. They can be arranged either in series or parallel. This way you can create band
passes and band stops.
HIGHPASS - HIGH-PASS FILTER
The first filter is a high-pass filter with a roll off curve of 12dB per octave below the cutoff
frequency. Only frequencies above the set Cutoff point can pass through this filter unaffected.
<HIGHPASS-CUTOFF> - HIGH-PASS CUTOFF FREQUENCY
This parameter varies the frequency below which the bass is filtered out.
<HIGHPASS-RESONANCE> - HIGH-PASS RESONANCE
With this parameter you control the characteristics of the filter at the cutoff frequency. High
resonance settings cause an increase of the level in the area of the cutoff frequency. As a result the
filter has a nasal sound characteristic. An extreme resonance setting causes the filter to go into
self-oscillation and creates a sine tone, at the cutoff frequency. This is the reason the pitch of this
sine tone can be adjusted with <HIGHPASS-CUTOFF>.
<HIGHPASS-ENV-MOD> - HIGH-PASS FILTER - ENVELOPE SENSITIVITY
This parameter varies the amount by which the envelope generator modifies the HPF cutoff
frequency. When the control is positioned in the middle it has no influence. With negative values,
the greater the deflection of the envelope the lower the cutoff frequency of the filter. (ie. during
the envelope's attack, the HPF opens up letting more bass through.) With the knob set at positive
values, the cutoff frequency is made higher in proportion to the envelope amplitude, so the HPF
effect becomes much more severe on the peaks.
LOWPASS - LOW PASS FILTER
The POLYMORPH's other filter is a low-pass filter, which has a switchable rolloff curve of either
12dB or 24dB per octave. The LPF filters out the treble above the set cutoff frequency and only lets
the bass through.

[LP24DB] - 24DB ROLL OFF CURVE
With this button you can switch the rolloff curve of the low-pass filter between 12dB and 24 dB
per octave. The rolloff curve decides how much the frequencies above the cutoff frequency are
attenuated. At 12dB rolloff the over- tones with double the frequency of the cutoff frequency will
be damped down to -12dB (one quarter) of the original level. With a rolloff of 24dB per octave the
overtones would be reduced by 24dB (one sixteenth ) or the previous level at every successive
octave.
<LOWPASS-CUTOFF> - LOW-PASS CUTOFF FREQUENCY
This knob varies the frequency above which the treble is filtered out.
<LOWPASS-RESONANCE> - LOW-PASS RESONANCE
With this parameter you control the characteristics of the filter at the cutoff frequency. High
resonance settings cause an increase of the level in the area of the cutoff frequency. As a result the
filter has a boomy sound characteristic. An extreme resonance setting causes the filter to go into
self-oscillation and create a sine tone, at the cutoff frequency. This is the reason the pitch of this
sine tone can be adjusted with <LOWPASS-CUTOFF>.
<LOWPASS-ENV-MOD> - LOW-PASS FILTER ENVELOPE-SENSITIVITY
This parameter varies the amount by which the envelope generator modifies the LPF cutoff
frequency. When the control is positioned in the middle it has no influence. With negative values,
the greater the deflection of the envelope the lower the cutoff frequency of the filter. (ie. during
the envelope's attack, the LPF closes down more letting less treble through.) With the knob set at
positive values, the cutoff frequency is made higher in proportion to the envelope amplitude, so
the LPF effect becomes much less severe on the peaks.
ENVELOPE-GENERATORS
Envelope generators can automatically modify certain characteristics of your sounds over time. The
severity of their action can be adjusted with these controls. The envelope starts when it is triggered
by the user eg. by playing a key on the keyboard.
The POLYMORPH has four independent envelope generators. Three of these can be controlled
directly on the operating surface. These three envelopes each have four parameters and are placed
under each other in order. The first one controls the cutoff frequency of the High-pass filters, the
middle one the cutoff frequency of the low-pass filter and the third the volume of the sound. The
four adjustable control knobs are the same in their behaviour for each of the three envelope
generators. The fourth envelope is provided for the pitch, and can be found in the oscillator edit
menu.

<ATTACK> RISE TIME
This parameter determines the amount of time it takes for the envelope level to travel from the
initial to the peak level (when the key is struck). In the case of the VCA-EG this means, how much
time has passed until the highest volume is reached. Percussive instruments need a very short
attack time and string sounds are usually quite long. For the filters, it controls how fast the filter
opens (or closes depending on the <ENV-MOD> setting.)
<DECAY> DECAY TIME
This parameter determines how fast the envelope falls from the peak to the sustain-level after
passing through the attack phase.
<SUSTAIN> HOLD LEVEL
This parameter is not an indication of time. Rather it is a level that is held after the decay time until
the key on the keyboard is released. For the VCA-EG, if the sustain level is regulated to 0, the
POLYMORPH sound would end after the decay phase regardless of how long the key is held. If the
sustain level is higher than 0, the corresponding tone will be held until the key is released and the
release time is finished.
<RELEASE> RELEASE TIME
This is the length of time that the sound can be heard after releasing a key. You can adjust the
release time between stopping abruptly or slowly fading away, or in the case of the filters, how long
before the filter closes after the key is released.

LFO-Section

The LFO provides a cyclical (recurring or repeating) change of a parameter. The POLYMORPH has
3 LFOs. You have 3 buttons to choose which of the 3 LFOs you would like to work with. All of
these LFOs have a fixed modulation destination.
[PWM] PULSE WIDTH MODULATION (LFO-1)
This button puts the parameter of the pulse width modulation LFO under the control of the LFO
section (hence varying its amplitude / volume over time for a tremolo effect.) This LFO creates a
modulation of the pulse width of oscillator 1. If oscillator 1 is in the sync operation mode, the
frequency of the auxiliary oscillator is controlled by this LFO.
[VCO-FM] FREQUENCY MODULATION OF THE OSCILLATORS (VIBRATO) (LFO-2)
This button puts the parameter of the frequency modulation LFO under the control of the LFO
section. This LFO creates a vibrato.
[VCF-MOD] FILTER CUTOFF FREQUENCY MODULATION (LFO-3)
This button puts the parameter of the filter cutoff frequency LFO under the control of the LFO
section. This LFO causes the opening and closing of the filter. In the edit menu the modulation
depth for the high and low-pass filter can be varied. In addition this LFO can influence the volume
of the signals. Check the "Amp" menu for that.
<LFO-WAVE> WAVEFORM OF THE MODULATION GENERATOR
This control is used for the selection of the waveform, with which the LFO swings. The available
waveforms are printed on the operating surface.

SIN = sine
SWD = sawtooth down
SWU = sawtooth up
SQR = square
TRL = triangle
RND = random
<LFO RATE> SPEED OF THE MODULATION GENERATOR
This control is for the adjustment of the modulation speed. A special function is available with
values higher than 120. These are synchronized speeds. With this settings, the LFO's adapt their
speed to the speed of the internal or external sequencer.
1/16 - The modulation frequency represents 16 periods per bar.
1/8 - The modulation frequency represents 8 periods per bar.
_ - The modulation frequency represents 4 periods per bar.
_ - The modulation frequency represents 2 periods per bar.
1/1 - The modulation frequency represents 1 period per bar.
2/1 - A cycle passes through after two bars.
4/1 - A cycle passes through after four bars.
<LFO DEPTH> LEVEL OF THE MODULATION
This control sets the depth of the modulation effect.

SEQUENCER SECTION
The user surface of the Morph sequencer is at the bottom left side of the front plate.
The POLYMORPH provides four morph sequencers simultaneously. A morph sequencer is used to
create lively synthesizer lines or perhaps a periodic sound effect.
The morph sequencer of the POLYMORPH has 4 rows each with 16 steps. On the POLYMORPH
the first row is called the pitch row, since it's responsible for the pitch. The second, third and fourth
row each control a freely selectable sound parameter. The steps of the rows are called up one after
another in a selectable sequence. When the sequencer is started the sound parameter is changed
automatically. Every sound parameter row and also the order of the pitches can have various
numbers of steps, which create sequences that repeat themselves after several cycles. In addition
the sound parameter sequence can be played in a different order from the pitch. Some single steps
can be turned off to achieve a rhythmic variation. To present all of the parameters of the
sequencers simultaneously, a much large user surface would be needed.
8 steps of the sequencer can always be edited at the same time. In addition only one row can be
edited, there is a choice of the pitch or one of the three parameters stepping order. The 8 number
buttons can be setup to have different functions. If we had put all parameters on the panel with
one button per function, you would have additional 112 buttons and 56 controls to look over.
Instead, you will find more parameters in the edit sequencer menu. Here are the functions of the
buttons and dials:
[PAGE] – TOGGLES BETWEEN STEPS 1-8 AND 9-16
With these buttons you can switch back and forth between steps 1-8 and 9-16. When pushing
[PAGE-RIGHT] the lower line on the display will show for a short time the following:
Seq Steps 9-16
If this does not occur you are in an edit menu of the POLYMORPH and will have to push [EXIT] to
leave the edit sector.
[PITCH] SELECTION OF THE PITCH ROW
This button puts the [NUMBER 1-8] and the <VALUES> on the pitch row. With <VALUE> you
change the pitch of the respective step.
[LINE 1-3] SELECTION OF THE PARAMETER ROWS AND ASSIGNING THE PARAMETER
ROWS
This button puts the [NUMBER 1-8] and the <VALUES> on the corresponding number of the
parameter row. All of the rows 1-3 (line 1-3) can control a sound parameter. When you hold down
one of the 3 [LINE]'s the display will show which sound parameter is controlled by the chosen row.
There are two possibilities to select the controlled sound parameter:
1.) You hold down one of the [Line 1-3] and turn the desired parameter on the Polymorph
surface.
2.) You hold down one of the [Line 1-3] and turn the <VALUE-TEMPO>. With
<VALUE-TEMPO> you can select the desired parameter.
