It works fine!
This app works exactly as advertised. There is very definitiely a manual under the settings menu.
It is for recording human voice beatbox sounds, but you could connect to other inputs with a mic cable. Up to 32 tracks can be recorded (I didnt try that many) and you can playback 8 at a time.
The hardest part is getting the timing spot-on: an external metronome is really useful, but even then it is hard to hit the record button right on time.
