Simultaneous RR Group Playback

[Levitanus]

I faced the same problem with function setMultiGroupIndex: no matter, what I try ‒ I hear all RR groups, that are mapped to the key.

And I'm sure this function is what I need: I have halftone trills in groups 1-2 and wholetone trills in groups 3-4, and, while playing legato I want to choose between half and whole tone, based on intervals being played. It will be huge logic overhead, if splitting all such articulations to different samplers.

I've succeeded to do this with setMultiGroupIndex, but not with setMultiGroupIndexForEventID. But still looks fine. Maybe there is a sense to check the behavior of the last one?
