Unison "spread" for all 3 oscillator parameters

[tomatoKetchup]

A really neat feature would be to have the ability to offset the "Wave", "Timbre" and "Shape" values for all 4 oscillators when in unison mode (similar to the pitch spread) to create slight timbre differences between them.

Just throwing the idea out there.

I like this, maybe even some drift setting if the cpu can handle that much.
