POLYPHONIC MODE
This mode allows you to use the four CV channels polyphonically. This lets you play 4 separate analogue
monosynths as if they were one 4 voice poly synth. Some four 4 voice poly synths such as the Oberheim
OB-4 can be fitted with CV/Gate/Filter inputs allowing it to be played polyphonically from the PRO-4. The
poly mode parameters can be found after the System parameters.
POLY> CHAN ASSIGNMENT All Channels = Mono
(default)
A+B=Poly C+D=Mono
A+B+C=Poly D=Mono
A+B+C+D=Poly
- This setting lets you decide which PRO-4 channels are assigned for use in poly mode.
POLY > NOTE ASSIGNMENT Regular Cyclic Mode (default)
Memory Cyclic
Reset Mode
- This setting decides how the PRO-4 assigns incoming MIDI notes to the PRO-4 poly channels being used
(as set by CHAN ASSIGNMNT above). This setting only has effect if the PRO-4 is in poly mode.
Regular Cyclic Mode;
Incoming MIDI notes are assigned the next free CV channel. (Even if it is the same note played
repeatedly).
If, for instance you have channels A+B+C+D set to poly, each time you play a note it will step through
and assign channels A, B, C, D then back to A again to it as you play.
If you hold a note, new notes will be assign to the next channel in the line free.
If all channels are assigned to held notes, the next newest note will use the CV channel first held.
Memory Cyclic;
When you play four notes four channels are assign in a cyclic manner similar to the regular cyclic mode. If
you play any of those same 4 notes, the same channels as previously assigned will be used for the same
four notes.
If a new note is played, the oldest channel assigned will be assigned to the new note.
Reset Mode;
As you play, the lowest free channel (A being the lowest) is assigned to the new note.
When in poly mode, certain parameters for channels B, and C and D if assigned to poly mode, will be
slaved to channel A.
If you scroll to `CV >A NOTE PRIORITY`, you will see `Poly mode Master Chn`. In poly mode, Note priority is
not used.
If you scroll to the other channels assigned to poly mode, you will see `Slave to channel >A` for
parameters;
`CV >x MIDI` (where x is B, C, or D),
`CV >x NOTE PRIORITY`, and
`CV >x TRIGGER MODE`.
The values for these parameters will be taken from channel A`s settings.
The previous settings for these parameters are not overwritten by channels A`s settings, they are held in
memory and will be reset back when the poly mode is switched off back to mono mode.
If you have auxiliaries linked to any of the poly CV channels, and the auxiliary source is velocity, the
auxiliaries will take their velocity levels from the note they are assigned to, giving you polyphonic velocity.
One interesting feature is that you can set different Pitch Bend and Transpose ranges, LFO settings, etc.,
for each of the poly voices, allowing interesting effects to be produced.
