Avalon OS Updates
Avalon OS v1.3 download

OS Update Procedure

The Avalon operating system is updated via MIDI SysEx. MIDI SysEx is used for its robustness and lack of dependency on the operating system and usb drivers. You’ll need a MIDI utility such as MIDIOX for PC or SysEx Librarian for Mac to update your OS. Both are free downloads:
