Great app, but there seem to be some bugs.
The column furthest to the right and the third in from the right on the Tech House session refuse to play at full volume. Even the highest volume setting is barely audible. So far it only seems to be that one session and even changing the sound assigned to the pads doesnt fix it. Those sounds play too quiet too.
