Firmware installer
- Connect the FM-1 to this computer with a USB cable and turn it on.
- Close the SHRUB editor, M-VAVE's updater and any music software that uses the FM-1.
- Choose the firmware package, then press Install. Allow MIDI when the browser asks.
If something goes wrong
Keep the cable connected until the installer says it's done (about two minutes). The FM-1's screen shows SHRUB UPDATE while it is in update mode.
If the install stops part way, the FM-1 stays in update mode, also after it's turned off and on: run the installer again and it carries on. If nothing was written yet, it goes back to its firmware by itself after a minute.
USB recovery mode, for the recovery tools: hold OCT− and OCT+ while turning the FM-1 on with the USB cable connected (in update mode too).
The installer updates an FM-1 running M-VAVE's own firmware or SHRUB. If it runs another firmware, and the installer doesn't find it, put M-VAVE's firmware back on first, then install SHRUB.
On Windows, only one program at a time can use the FM-1's MIDI port: close the others first.
