allow env3 to modulate per-part effects (at least in mono mode)

  • currently when envelope 3 is assigned to modulate per-part effects like the "FreqShifter Freq" it has no effect and the explanation was in 2011 that env3 is per-voice, but effects are per-part. However LFOs even when in poly mode are able to modulate FreqShifter Freq. But even if making it possible in poly mode would be so difficult, could it be made possible at least in mono mode please?
