If you like dub techno music, you can turn your phone into endless dub techno "mix" or "live" generator.
Just turn it on, press Start and listen as a usual player, but music will never end.
Main theme or "track" will change in every 3-4 minutes automatically.
All music is created right on your phone, no streams and samples, so it can work offline without internet connection.
To switch to next track tap Reset button.
To record/stop recording created music tap R icon.
Also it has "mute" feature - tap on gear icon and you can mute chosen instruments and use app as a chord generator, for example.
