You have to check it out. I'm reading the docs now, and it looks to br highly useful as a midi controller.

It can send note on / off and velocity. It can also send CC. Some patterns are far easier to program in tidal than to manual play or enter on a piano roll in any daw. It also has a built in arp and entire chords can be played / arped. It can also distrusted chords and notes and change them each cycle. Lots of stuff packed in there. It can also do any division against any other, e.g. 7 against 4.
