SmackTop 0.1

SmackTop is an open-source utility for Mac laptops (after 2005) that transforms accelerometer (Sudden Motion Sensor) data into MIDI data and audio impulses. This enables users to control their favorite DAW by tilting and smacking their laptop. SmackTop has two controller types: Tilters and Smackers. Tilters translate the left/right (i) and forward/backward (j) tilt of the laptop into MIDI CC values. Smackers use the change in acceleration (jerk) to trigger MIDI CC, noteOn and/or audio impulses designed to trigger 'sidechain' effects.
