Hello GP community, I have a question that relates to my MIDI foot controller, which is the Line 6 FBV3. The device has a small LCD display to show the patch name, and I was just wondering whether anyone knows of a method to customise this?
As an aside, can anyone explain to me how the controller reads this information? I imagine the MIDI PC message contains a program descriptor field … ?
Does it support reception of MIDI Sysex messages to change the text? If so, you might be able to do something like I did to control the GT Mastermind MIDI Pedal Controller.
Otherwise, if they have something proprietary, then it would be necessary to create a 3rd party extension to control it. Whether anybody other than Line 6 could do this depends on how open they are about their own API
So I tried a (very) quick and dirty hack, converted a 16 character ASCII string to hex, and added the magic leading hex digits as indicated by the linked code, and set a song part to send the crafted SysEx message to the device upon changing to that part in GP4, however my first attempt didn’t work, in fact I think the device simply ignored the message.
