Punchmate

Punch-card rhythms for iPhone & iPad — patterns, drums, AUv3

Rhythm Cards

Factory patterns plus your own Custom cards — insert, edit, rename, and keep them for the next session.

6×16 Sequencer

Six rows (A–F), dual voice per lane, amber steps, mute/solo mixer — classic rhythm-computer layout.

Transport & Clock

START-STOP, HOLD, VOLUME/SPEED, and hardware-style clock multipliers (×5…×16).

AUv3 + Studio

Standalone app or AUv3 in AUM / GarageBand / Cubasis — drum patterns in your mobile chain. MIDI out coming next.

Punchmate: punch-card rhythm computer

A digital rhythm box for iPhone and iPad, inspired by early European program-card drum computers — rebuilt as an original AudioMusik instrument.

Load a card, punch steps, switch voices, and run the groove. Build Custom cards, rename them, and they stay saved between sessions. Use it as a standalone drum computer, or drop it into your iOS studio as an AUv3.
