Forum member and programmer AlGrenadine provides a handy editing app for the Axe-Fx II, AX8 and FX8: FracPad. It provides all the tools to adjust your sound, edit and manage presets, blocks etc, from a tablet, smartphone or computer.
It allows naming scenes, attaching modifiers to any parameter, displaying real world amp/drive panels, searching parameters by name, displaying a tuner based on the Axe-Fx III's tuner UI, various knob skins, importing AX8/Axe-Fx/FX8 presets on every machine, turning the metronome on/off, and many other things.
A free version is available for Windows and OS X.
- Full and "lite" versions for Android, and free version for Windows and Mac
- Commercial version for iOS
- "Lite" version for iOS
Connecting FracPad to mobile device
This requires a compatible USB adapter, called "USB OTG". This works with the AX8, FX8 and Axe-Fx II models.
No reliable wireless solution (Bluetooth) has been found yet.
Axe-Fx II and iOS (wired and wireless)
Wired – Requires a MIDI-to-USB interface, because the USB port on the Axe-Fx II doesn't operate as USB host. Use a USB-to-MIDI interface like Roland's UM-One in conjunction with the "USB camera adapter" for Apple devices.
Wireless – Bluetooth. The Yamaha MD-BT01 interface is recommended. It connects to the MIDI IN and OUT ports on the Axe-Fx II. Launch the app "Midimittr" (AppStore) to enable the communication, followed by launching FracPad.
AX8/FX8 and iOS (wired and wireless)
Wired – Requires a USB connection, because the AX8 and FX8 do not support editing through MIDI. Use the "USB camera adapter" for Apple devices.
Wireless – Bluetooth. Try Yamaha's UD-BT01 interface and verify that it runs firmware 1.03 or later (run the Yamaha UD/MD utility, available in the US / Canadian app store). Launch the app "Midimittr" (AppStore) to enable the communication, followed by launching FracPad.
Axe-Fx II / AX8 /FX8 and iOS (wireless)
A Bluetooth connection requires Bluetooth LE (Low Energy), so make sure that the iOS device handles Bluetooth 4.0+. This requires at least an iPad 3 or iPhone 4s (source).
Bluetooth operations on Android are not officially supported, so use at your own risk.
