Holding the simplicity of eighties instruments and carrying their raw heritage to you, it turns your device into a pocket beat making companion. I believe that designing a pure interface, simply displaying your machine without any distraction, was the best way to reflect the spirit of the period it was born.

Version 2.0 release notes

Version 2.0, the drum machine moves into the studio. **Audio Unit (AUv3)** The machine becomes an instrument you load straight into GarageBand, AUM, Cubasis, Logic or any other compatible host: its front panel appears in the host's window, its tempo follows the transport, and its state is saved with your session. Seven separate outputs — the full mix and each instrument group — so you can mix the kit track by track. Fifteen automatable parameters: volumes, accent, tempo, fill-in and effects. **MIDI** The machine now sends every hit as a General MIDI drum note, accents included, to your other apps and MIDI interfaces, to Audiobus, and to the host when running as an Audio Unit. The channel is set in the settings. **Audiobus 3** Updated to the latest SDK, with a MIDI port alongside the audio port, remote Start/Stop triggering, and the machine's complete state saved in your Audiobus presets. **Mac version** The app now runs on the Mac, included in your purchase: a window in the machine's own proportions, menus, keyboard shortcuts, and knobs you turn with the scroll wheel or trackpad. **Built-in settings panel** No need to leave the app any more: every setting is gathered in a panel styled like the machine itself, one tap on Settings away — accent, muted instruments, register sync, effects, MIDI, Bluetooth foot switch. It adapts to your device: on iPhone the sections stay reachable at all times and each page fits the screen, with no scrolling and no zooming. The iOS Settings remain available, and the two stay in step. **And also** Output limiter: no more clipping on busy patterns. Pinch to zoom and two-finger panning on the front panel. Haptic feedback on the pads. Bluetooth LE foot switch pairing and command learning from inside the app. No data collected.
