I feel like I'm missing something super obvious, but I can't figure out how to get variation between mod sources for each voice. The simplest example of what I'm talking about: LFO speeds change based on key, so the lowest note played would have a slower LFO speed than the higher notes. Both through using the keyboard as a mod source and the keytrack option in each LFO, the LFO always functions monophonically. Do I have to activate some option somewhere, is this a bug, or is it just that Pigments isn't designed to offer polyphonic modulation?
