µsiqke (musique) is my personal music instrument I perform with in my band, shy guy says. It's split into two components, the PureData synth, and an accompanying android app. A more detailed explanation can be found on tech.shyguysays.com
The PureData synth is a standard polyphonic synthesizer, with many configurable parameters, written in the form of a puredata patch. It accepts MIDI in (or OSC) to control the notes. The Android app is a custom made OSC controller, designed to interface explicitly with the patch. It's large buttons and X/Y pad make performance both more expressive and less prone to mistakes.
