to complicated for learning by doing but manuals aren't available neither! At least I could test all parts for free, just by accepting (to much) uncomfortable advertising. With an extensive manual probably the best and most complete music suite that is available for none-apple phones/tablets.

Meh. I can't seem to find the hold or sustain button anywhere. Also how do you assign two different banks to each keyboard to play simultaneously? Or maybe it doesn't exist. It's a little lacking not very thought out carefully just crammed as much as they could in to the app as possible, needs work.

Thanks for your feedback, Joseph. 1) Each ADSR envelope has a sustain slider (not button), 1x amp env, 1x flt1 env, 1x flt2 env. Or do you mean the sustain "pedal"? If so, ... left side of the keyboard. 2) If you mean the different VA tracks, then all you have to do is to load a different preset for each track instance.

ui is for tablets, not for phones. don't know about sounds quality, but ui definitely is not better than caustic's. and i can't go further to test other things as your ui puts strain on my eyes (i'm on 6 inches phone).
