READ THIS BEFORE YOU UPDATE FROM 1.x to 2.x

1 - BEFORE YOU UPDATE, store a backup of your presets.
The update needs to make changes to the patch memory, it's been toroughly tested but just in case something happens, you have a backup.

2 - Downgrading is not possible (but you won't want to, really...)

3 - How to update:

Plug your MM2 to your computer (via USB) while pressing both A and B buttons.
Screen should say "Firmware Updater"
Send the syx (SYSEX) update file with SYSEX Librarian, MIDI Ox or Bome Send SX, all should work (use USB MIDI only)
