Return to M-VAVE's own firmware
This puts M-VAVE's official V15 back on an FM-1 that runs Noodle (or Felucca, or a firmware built on it). It first saves a complete backup of what is on the FM-1 to this computer. Use Chrome or Edge, a USB data cable straight into the computer, and close other apps that use MIDI.
The installer here is Felucca's own, unchanged.
