This is a musical instrument for tablets running Android 2.2 or higher.
Choice from 2 sound sources: a Moog-like synthesizer and a Hammond-like organ.
These can be played with one of 3 on-screen keyboards.
Preset patches as well as manual controls.
This project is open source (Apache license).
If you have an Android development environment installed, then download this, unpack, read the README, compile.
This was faked somewhat: the on-screen keyboard was controlled by computer via bluetooth. Somedays when I have practised some more, then a real demo will appear here. Also Android's inherent audio latency is hampering, it takes time to get accustomed to this.
