It maybe a long shot, and i might not be explaining it very clearly, but having multiple patterns playing at once: how feasible is it? I know by definition the machine does not work this way, but what I would like to have the ability to do is: polymeters. and being able to use varying lengths of patterns for separate tracks. like looping 4 bars at a drum and 8 bars for a bass track for example
As much as I would love this feature too I reckon it will be basically unlikely or impossible to add to the softwares infrastructure. You might be better off sending it MIDI clips via USB or 5-pin
Individuel tracks lengths, which I understand your talk about in the last part, has been confirmed not being added:
