Every control on an interactive top panel — three switches, and the layouts that multiply them.

Every jack on an interactive rear panel, including the input that does two jobs and the output that is XLR only.

The numbers that answer a question, with the FM9 comparison on every line that differs.

The two axes — and on an FM3, channels are how you get variety out of one amp block.

12 by 4, one amp pair, and a CPU budget you manage rather than caps you hit.

Every model Fractal themselves describe — and an honest account of the ones they don't.

Input trim, output level and preset level do three different jobs. The first one does not change your tone, however much it looks like it should.

What a User Cab is, how to get one onto the unit, and the file extension that looks right and does nothing.

FRFR, front of house, into a real amp, or four-cable.

Why Fractal MIDI works differently from everyone else's, and the mapping that lets a one-message controller drive a scene-based rig.

Straight answers to the things people actually ask.

Symptom, cause, fix — including what is documented behaviour rather than a fault.

Presets live in banks of 128, so backing up "your presets" usually backs up a quarter of them. Plus the version note that saves you later.
