Install Quasar

This page installs Quasar on M-VAVE FM-1 connected to this computer, over USB MIDI. It works in desktop Chrome, Edge or Opera. It talks to FM-1 directly: nothing is uploaded anywhere.

Read this first. Quasar is unofficial firmware, not made, endorsed or supported by M-VAVE or SOMA Laboratory. Installing it replaces FM-1's firmware and may void any warranty that applies to your device. Interrupted update can leave FM-1 unable to start until it is recovered. Saving Quasar sessions overwrites any projects another firmware left on device. Software comes with no warranty of any kind; you install it entirely at your own risk. Full disclaimer.

Loading firmware…

I have read warning and disclaimer. I understand that installing Quasar may void my FM-1's warranty and that I install it at my own risk.

Before you start

Use USB cable that carries data (some carry power only), plugged straight into computer.
Switch FM-1 on, and close any other program using MIDI (DAW, M-VAVE's app).
When browser asks to let this page control MIDI devices, allow it: update is sent as MIDI system-exclusive messages.

After installing

Switch FM-1 off and on once. Quasar renders on both of FM-1's processor cores; if 2nd core was ever stopped (after fault on it), it stays stopped until power is switched off, and screen says 1 CORE at start-up.

If something goes wrong

Stopped part-way? Reload this page and install again: FM-1 left in update mode is found and write is finished. If FM-1 starts but does not answer over USB, put it in chip's own update mode — hold OCT− and OCT+ for 5 seconds while it runs — and restore firmware with Melodee's recovery tool (macOS, Linux, Windows) or FM-1-transporter.

Prefer command line? Build and install from source.
