And I haven't used it myself, but it's
possible that harmonySEQ might
be of interest to you, too.
I recommend against harmonySEQ, for several reasons. One serious reason
is the bad timing, that has nothing to do with human touch, it simply
can't play in time.
For making live music I wouldn't use "sequencing", at least not to play
drums. Why not playing synth drums by drum pads without using a
sequencer?
