Fractal Unit Compatibility
Which Fractal units AxeBlock EDIT supports on iPhone and iPad today, which have are confirmed by beta testers, which have editing that isn’t yet confirmed on a real unit, and which connect and identify only.
// Supported · Full editing
Supported
Axe-Fx III
Original, Mark II, Turbo
✅ Supported
Deep, real-time editing over USB: every block and type, grid editing (place, move, wire, delete), scenes, channels, modifiers, the MIDI block, presets, tuner and tempo. Verified on a real III (firmware 32.06).
Supported
VP4
Single variant
✅ Supported
Full editing over USB: every control VP4-Edit shows, chain slot replace and move, types, scenes, channels, modifiers including Add Modifier, controllers, output levels including Preset Balance, scene levels, preset EQ, and Save. Verified on a real VP4 (firmware 4.04).
Supported
Axe-Fx II
II, Mark II, XL, XL+
✅ Supported
Full editing: browse presets, edit supported blocks and parameters, grid, and Save. Calibrated against a real Axe-Fx II XL. On iPhone and iPad, connect by Bluetooth (WIDI) or 5-pin MIDI — its USB isn't iPhone- or iPad-compatible. On a Mac, USB works with Fractal's driver.
// Confirmed by beta testers · Editing live
I don’t own these. Beta testers ran AxeBlock EDIT on their own units and reported back; what they confirmed is listed, and what they found still open is too.
Confirmed by testers
FM9
Mark II Turbo, Turbo, base
✅ Confirmed by a beta tester
USB or Bluetooth (WIDI). Confirmed on a real FM9 by a beta tester (firmware 12.00): presets load, scenes switch from the app, and edits land on the unit. Amp, Delay, Reverb, Flanger, Multitap, Cab and most blocks. Grid editing and preset Save / Save As are included. Still open: changes made on the unit itself (footswitch bypass, front-panel knobs, scene switches) don't yet show in the app.
Confirmed by testers
FM3

I confirm every unit on real hardware before AxeBlock EDIT claims it, and I don’t own every unit. If you own one that isn’t confirmed yet, the Fractal Unit ID capture is how you can help. It reads your unit in the browser and records how it answers. It’s read-only and can’t change, save, or write anything on your gear.
