Using MIDI
There are four major functions that can be performed via MIDI on the Tube Fex: change Programs/Banks;
change effect parameters during performance via Continuous Controller messages; store presets on remote
storage devices via MIDI system exclusive messages; and remotely edit and store any user accessible
parameter using special Remote Editing

messages. The Tube Fex can also be setup to transmit MIDI
program change messages when a new program is selected from either the front panel or via MIDI.
