CUSTOM FIRMWARE / M-VAVE SMK-37 PRO

Less light.
More MIDI.

Your keys. Your controls. Nothing in the way.

MIDI Only reduces the SMK-37 Pro to its essential controller functions. Play over USB, TRS or Bluetooth MIDI. The pads stay dark, while a quiet black-and-white display keeps your octave and controller values in view.

Install in your browser.

Use desktop Chrome or Edge. Connect your SMK-37 Pro with a USB data cable, close other MIDI applications and open the installer. Back up important data first. Keep power and USB connected until the installer confirms completion. Original Pro V16 recovery is included.

Bluetooth MIDI is enabled automatically. On a Mac, open Audio MIDI Setup → MIDI Studio → Bluetooth and connect the controller. The sustain pedal sends CC64 to every available MIDI output.

For SMK-37 Pro only. This firmware is not compatible with the Elite or FM-1. Basic operation and Bluetooth MIDI have been confirmed by the owner on v0.1.1.
