Good grooves with bad time stretching
The grooves definitely are the best part of this app, fun to play to and much more alive than simple metronome apps. The quality of the time stretching though isn’t very good, even changes by one bpm produce nasty artifacts especially in the transients. This is especially annoying with e.g. the selection of pop grooves, where 4 from 8 grooves have a tempo of 172 bpm and only one in the whole 120-140 bpm range (which would be rather common for pop). The possibility of marking favorites would be very useful as the names of the grooves are very generic.
