Back up sessions and presets

This page copies the sessions and presets stored on an FM-1 running Tonitor to a file on this computer, and puts them back from that file. Use it before you try another firmware (it may erase or overwrite them): when you reinstall Tonitor, restore the file here. It works in a desktop Chrome, Edge or Opera, over USB MIDI, and needs Tonitor 0.47 or later on the FM-1. Nothing is uploaded anywhere: the file stays on this computer.

Not connected

Connect the FM-1 with a USB data cable, switch it on, then find it.

Restore

Open a backup file, then write it to the FM-1. Every session and preset table in the file replaces the one with the same number on the FM-1; the others on the FM-1 are kept.

Open a backup file

I understand that the sessions and presets in the file replace those with the same numbers on the FM-1.

Notes

Close any other program using MIDI (a DAW, M-VAVE's app), and allow MIDI access when the browser asks: the sessions travel as MIDI system-exclusive messages.
The FM-1 keeps playing while this page works, but writing to its flash silences the audio for a moment each time.
Each session and preset table is copied whole and checked: one that does not arrive intact is not written.

The page (js/backup.js) and the part of the firmware that answers it (firmware/src/backup.c) are GPL-3.0, on GitHub.
