How exactly does this work? Specifically when it comes to regular non-unison polyphony, how is the order of voices chosen? If I assign a target parameter to be modulated by the voice index, how do I know which voice will be chosen?
Thanks

I always wondered about this too. Are the offsets essentially static? So like if I've got Voice Index assigned to fine tune with a relatively low modulation depth (say 0.07), is voice 1 always being modulated .04 (picking random values here), and voice 2 .02, and voice 3 0.05, etc. (whatever the random value results in)?
Are these offsets bipolar? So like in the above example, where the Voice Index mod depth is something like +0.07, might some voices have negative values? And if I set a mod depth of -.0.07, would that just essentially invert the modulation where if Voice 1 was previously positive, now it's negative and the opposite would happen for any voices with negative offsets?
Just trying to understand how to get the most of the voice index.

Guys, I misunderstood the OP, my apologies - I realize he's referring to Voice Index, and I was thinking of Diva's Voice Map Modulators. Give me a few minutes and I'll clarify my explanation.

Voice Index:
I'll give an example - say you use Voice Index on oscillator pitch and set the mod depth to 100.
Then what happens is, the 8 voices are spread out in how they are affected between -100 and +100.
So voice 1 would then be affected by -100 on pitch, voice 8 by +100, and the others spread evenly in between.
The order of the voices depends on if you use voice reallocation or not (see TWEAKS page). But let's say you start with an init and play a C major scale over an octave, then that would trigger voices 1 to 8 in neat succession. But once you e.g. hold a chord and play a melody above that, or other shenannigans, the voice sequence will get more irregular and less predictable.
Meaning, using Voice Index for a predictable, calculated modulation will get out of hand quickly. I'd advise using it where a more random result doesn't hurt.

And as you suspected, setting the mod depth to negative 100 instead, that spread is inverted. All modulation would flip polarity, voice 1 would then go to +100 and the subsequent voices downwards with voice 8 at -100.

So the depth of modulation increases as you cycle through the voices in order?
Establishing that order is the question
Thanks

Sort of. I tend to look at it from the perspective of the currently set value of the target parameter, so I'd probably say, when cycling through the voices from 1 to 8, in the negative range the distance "to me" decreases, while in the positive range the distance "from me" increases.
The 8 voices are spread evenly in a bipolar range from negative mod depth value to positive mod depth value.
If we assume a neatly ascending voice order (1, 2, 3, ... to 8 ) and modulate some target with a mod depth of +100, then this happens (I'm giving only rough values here):
Voice 1 affects the target with -100.00
Voice 2 affects the target with -71.43
Voice 3 affects the target with -42.86
Voice 4 affects the target with -14.29
Voice 5 affects the target with +14.29
Voice 6 affects the target with +42.86
Voice 7 affects the target with +71.43
Voice 8 affects the target with +100.00
So, an even spread in that range of -100 to +100.

I already explained that the voice order starts out regularly and predictably, and if you only ever play one single note at a time, never two notes overlapping, then it could stay that way.
But once you start playing more notes simultaneously, holding chords, using the sustain pedal, etc., all the nice things that keyboard players do, then you'll end up with a different note order quickly.
Hence my advice to use voice index modulation more as a random-ish source, where each voice gets their own amount of something and where a predictable order of that is less important.
