Installer

Installs PRO-8000 on a Behringer PRO-800 over USB, sets up its patch memory, or takes it back to the stock firmware. Works in Chrome or Edge on a computer.

Not connected

Before you start, connect the synth by USB and quit SynthTribe and anything else that uses MIDI, including MIDI patchbays and other MIDI pages in any browser: a single message from one of them makes the bootloader refuse an update. Editor tabs in this browser step aside by themselves.
