Aftertouch • 3D Touch MIDI Controller for iPhone

Aftertouch is an expressive MIDI controller and synthesizer for iPhone inspired by the Soundplane from Madrona Labs, and the Linnstrument from Roger Linn Design.

Aftertouch uses Apple's 3D Touch technology to calculate velocity and polyphonic pressure messages, and supports MPE for sending pitch bend, modulation, and pressur on a per-touch basis.
