Multiple Synthesizer Groups filter by one processor (with ADSR mod and Velocity mod)
Ideally it should be done with a single synth group, but I find that doing so limits things a bit. For example, I haven't found a way to independently transpose grouped voices beyond one octave. (which is kind of essential) The hardwired transposition script affects all voices when applied to the group. Other modulation pathways only go up to an octave. So is suppose that is one sidekick question to this post;
How do you independently transpose Synth-Grouped voices (synths, samplers, etc) by up to at least 3 octaves?
In any case, the idea is to reduce cpu gobbling.
