AxeBlock EDIT: your Axe-Fx, from your iPad

A real-time MIDI editor for the Fractal Axe-Fx II and III — every block, the routing grid, and live performance controls.

Fractal makes the best amp modelers on the planet and the least portable editor for them. Axe-Edit lives on a desktop. Your rig doesn't. AxeBlock EDIT puts real-time control of the Axe-Fx II and III on an iPad.

What it controls

Presets and scenes with instant follow. Every block — amp, cab, drive, delay, reverb, and the rest of the 32 calibrated blocks — edited live, with the app and the unit staying in sync as you move knobs on either side. The routing grid, mirrored the way the hardware shows it. The II's looper transport, tuner, tap tempo, and the modifiers — an LFO, ADSR, envelope follower, sequencer or pedal attached to any knob and following in real time.

Wired or wireless

The Axe-Fx III is USB class-compliant: plug it into your iPad over USB-C and it shows up, no driver. The II family predates iOS-friendly USB, so it goes wireless — a WIDI Bluetooth-MIDI adapter on the 5-pin DIN ports, paired straight to the iPad. Both paths tested on real hardware.

Your presets are safe

AxeBlock EDIT works in the edit buffer — the same temporary space the unit uses when you turn knobs on the front panel. Nothing writes to a stored preset until you hit Save.

How it got built

Fractal doesn't publish the SysEx protocol. Everything AxeBlock EDIT knows was reverse-engineered by watching the bytes flow between Axe-Edit and the unit — first on the Axe-Fx III, then the II XL, from scratch. Owners of other Fractal hardware are helping extend coverage one unit ID at a time.

Getting it

Updated October 10, 2026: AxeBlock EDIT runs on iPhone and iPad, with an Apple Watch companion that isn't yet tested on a real Watch.
