Facts

Available on iPhone, iPad and Mac. Connects over Bluetooth LE MIDI (with a WIDI Jack or equivalent), Wi‑Fi (RTP‑MIDI) or USB. Bluetooth pairing happens inside the app on iPhone and iPad; on Mac you pair in Audio MIDI Setup.

Presets live in the app library. Save what you want to the pedal from any preset, in any order. Every knob on the front of the M1 MkII and every parameter behind it are on the same screen.

Built from the Walrus Audio M1 MkII user manual and audited before it shipped. The rest of the Walrus line is here.
