I posted in the Prophet Rev2 forum, as I've tested and confirmed this method of Voice-Component-Modeling on the Rev2... (A method to better model classic VCO poly synths, as well as real world acoustic/analog instruments)
http://www.VoiceComponentModeling.com/vcm.aspxThe exact same method
SHOULD WORK on the P08, as it has the same Gated Sequencer and Mod Matrix setup, from my understanding. I'd love to hear from some of you P08 vets, and get a confirmation whether this works on your board.
1. Set Osc1 and Osc2 fine tuning to -31. This offset will allow a center-point to work from in Gated Seq setup.
2. Setup the Gated Sequencera. Set Gated Seq to "Key Step" Mode
b. Gated Seq Lane 1: Will be routed/scaled to Osc 1 Freq via Mod Matrix
Set a reset at step seven (for a six voice emulation), and then dial in some random values between ~54-70 (with 62 being centerpoint)... Don't set Gated Seq Destination... leave it to destination: off.
c. Gated Seq Lane 2: Will be routed/scaled to Osc 2 Freq via Mod Matrix
Set a reset at the same step as sequence 1, and then dial in similar values here ~54-70... for per voice fine tuning. Again, don't set destination here, just the six values and the reset on step seven.
Note: Each incremented value will equal ~0.38 cents change to fine tuning (ie: +3 will equal a little over 1 cent sharp, and -3 would be a little under 1 cent flat. We're using 62 as the centerpoint for this setup... Above, we set Osc1 and Osc2 fine tuning to -31 to compensate for the centerpoint. Value of 62 means "perfectly in tune"
3. Setup the Mod Matrix for Fine Tune Scaling of Freq:a. Mod Matrix 1:
Set source to Seq 1, Set destination to Osc Freq 1, Set amount to 1.
b. Mod Matrix 2:
Set source to Seq 2, Set destination to Osc Freq 2, Set amount to 1.
Note: The value that is passed on to the Osc Frequency is going to be a fraction of 1. It will be the number set in the Gated Sequencer (62 for example), divided by the Max Gated Sequencer Value (125), multiplied by the Mod Matrix amount (1). So if the value of the Gated Sequencer step is 62, we're sending on 62/125*1 = 0.496 In step one, we set offsets of -31 fine tuning for each oscillator, so the net effect of a value of 62 should cancel out the offset and we should be perfectly tuned. You might wanna test / double check on the P08... I'm assuming the values scale the same as on the Rev2.
Alright, now test things out! Every key press should advance the Gated Sequencer by one Key Step, giving you a sort of virtual six voice instrument. Each step of the sequence will have unique values for Osc1 and Osc2 fine tuning, giving you a slightly different detuned character per-voice. It gives a more organic feeling, since each voice (and each osc) has unique tuning imperfections.
Try holding down a chord, and you'll notice the natural motion/phasing associated with each oscillator having slightly different tuning. If you tried to achieve the same sort of per-voice character using Osc Slop, you would have a bunch of randomness, and exaggerated/artificial tuning motion added onto the more natural wave motion of oscillators that have more stable tuning offsets...
If it's too wild sounding, try dialing back the Gated Seq values closer to 62 per step. If you want more character on a per-voice basis, scale the values out further away from 62. If you want to emulate a Memory Moog with one bad voice, set the step six to have much higher or lower values.
Note: For each step, you may want to keep the values of the #1 and #2 sequence close to each other, while still having slight variations. This emulates a situation where the voice as a whole has a sharp or flat tendency, yet the oscillators still have slight offsets.
If you're willing to sacrifice to additional mod slots, you can use an alternate per-voice detuning method, modeling intonation offsets. In this case, Route Mod Matrix 1 Destination to another slot with a value of 1 (or -1) (ie: Dest Matrix 3 Amount) Now for Matrix 3, set source to Note Num, destination to Osc Freq 1 and amount to 1. Now you have per-voice intonation offset for Osc Frequency. You'll want to scale all the Gated sequencer value way down (between 0-12 maybe)... and you may need to adjust main Osc Fine Tuning to compensate for the intonation tuning... ie: dial it in so around middle of keyboard things are close to perfect tuning, but as you get into low or high registers, then voices with higher values will have a sharp of flat tendancy (depending on whether you chose Mod Matrix 1 value of 1 or -1)
Tons of other options to try for virtual voice setups with per-voice behavior for a variety of destinations in the Osc section, but also you can target VCF, VCA, and Envelope behavior, and by using Mod Matrix scaling, you can get fine tuned variance when needed.
