If I understand it correctly it isn’t possible to set different playback speeds for each track. For example have T1 set at normal tempo, T2 at 1/2 tempo, T3 at 2x tempo and T4 at 1/4 tempo. You could then have the loop length determined by the slowest division being used which would also allow for longer sequences within a pattern to be made.
I would also like different playback methods like a modular sequencer, backwards, random, pendulum, ect. If this could be controlled via an LFO that would be amazing!
