1- can it record loops with lengths not snapped to the grid/bars/beats of the host tempo? (I.e. like an audio loop pedal - you press it once to start recording (or press a key on a midi controller) and press it once more to stop recording and start looping) Can it record snapped to the bars and beats as well?

2- can it record parallel tracks with different track lengths? (Polyrhythms etc)

3- does it have midi learn function (with AUM as host for example)?

I would like to use it for live midi looping with synths, and control it with foot pedals and such, hence the midi learn function.

Thanks!!
