Great, thanks for that!They are stable, repeatable per-voice offsets. This is by design and reflects measurements taken from vintage synths, where voice-to-voice variations would occur due to component tolerances. So for example in a vintage unit an oscillator’s tuning might be off by say 5 cents; the vintage knob will set the “depth” of that offset between in tune (at 4) and 5 cents off (at 1).
The only thing I dislike about the vintage knob on the P5/10 is that it applies offsets to the amp envelop sustain level so at certain settings you get audible sound after the decay stage has completed even if the envelope sustain is set to zero. I think they may have removed that when they added vintage knob to P6/OB-6; they certainly made some refinements to the implementation. I wish they’d tweak the algorithm in P5/10 to fix that too as zero should always be zero, otherwise it renders certain settings useless.
something like this is what I've tried to explain- yours sounds much more professionally founded...
so real randomization in the code/algorithm is off the hook then, and it is more a "pseudo randomization", done by the "even/odd voice counting logic" (combined with P5 or rr settings) which I've tried to explain as well, haha... thanks
It’s not random at all; the offsets are created by a lookup table. At a given vintage knob setting, the offsets applied to the parameters of a given voice will always be the same. (Contrast this with the original “slop” function of the P6 where the offset value constantly moved as it was basically being moved by a really slow LFO.)
There’s a very good explanation of this here https://www.voicecomponentmodeling.com/
Jason’s stellar and painstaking work has been incorporated into several synths.
