Two choices, one click, about five minutes. Your FM-1 shows up as Compas once Compás is on it.

Installs over M-VAVE's official firmware (V15 or V16), over BB1 1.5, 2.0 or 2.1, or over Compás itself. The firmware on the FM-1 is checked before anything is written.

Don't unplug or power off while writing. If a write is cut off, plug the FM-1 back in and press Install again: it picks up where it stopped.

This is the language the FM-1 starts in. Switch any time on the instrument: GLO, then turn ALGORITHM.

2 One click

Installs Compás : the band, the bass, the percussion and the 727. Keep a backup of any music on the FM-1 before changing firmware.

Try the legacy archive backup if this firmware supports it

Go back to the official firmware

Download the official FM-1 firmware from M-VAVE and choose the unchanged FM-1.fwsc here (V16 or V15). It's checked in this browser and never uploaded.

The official firmware can't open your Compás set list or 727 rhythms. Write down anything you want to keep first.

I have noted the set list and rhythms I need. An earlier attempt was cut off

If something goes wrong

FM-1 not found. Try another USB cable (some only charge), plug straight into the computer, and close other apps that use MIDI.

The browser asked about MIDI devices. Allow it, including SysEx: that's how this page talks to the FM-1. Nothing is sent anywhere else.

Compás won't start. Hold OCT− and OCT+ while you power on. The FM-1 opens update mode (UPDATE MODE · CONNECT USB). Then press Install again.

It stopped partway. Plug the FM-1 back in and press Install again with the same language. The write resumes.
