Regular envelop, LFO, Key mapping, Velocity mapping, ModX mapping, ModY mapping, Random and Unison mapping.
Haven't tried Random and Unison but perhaps there might be certain sounds that could benefit from Random for example -- like the attack portion of a Violin or the blow portion of a trombone instrument -- and would allow a greater variety of attack sounds with every keyboard press. Exactly what's needed to simulate alternate bow strokes -- if it does what I think it does.
So basically, one could meticulously come up with alternate tunings using the key mapping envelop. All envelops in Sytrus can be saved to an external file for later reuse, this means that a different patch could have an "alternate tuning" loaded -- however, any microtonal adjustments will have to be done by ear.
Correct me if I'm wrong guys
