If you want to build a custom MIDI system with a MIDI controller of your choice, you can control the AMP1 with the BluGuitar MIDI1 adapter interface. This turns the FOOTSWITCH jack on the AMP1 into a MIDI In jack. 
This allows you to recall all the AMP1 switching functions (Clean - Overdrive, Boost, Reverb, and the three overdrive channels selector) via MIDI Program Change commands. The MasterVolume , Gain / Clean Volume and PowerSoak can also be controlled via MIDI. 
The interface electronics will be from the AMP1fed. Therefore, no additional power supply or cable is required. 

Each possible switching state of the AMP1 can be called up by a MIDI program change command. This can create up to 128 presets . 

The assignment is made via the "MIDI-Learn" function on the AMP1 .
