I want to control the GT’s onboard looper using my MC8. There is no way to do this by CC messages via the “assign menu” of the GT, because the only target parameter in the looper category is looper level. Since I want to control rec/play/dub, stop, and clear by MIDI, I figured, maybe I could work around this by assigning this functions to CTL1-3 in the “control function” menu and map these switches to CC Numbers in “MIDI Settings”.
I’ve done some research and found this official Boss statement:
“When it comes to receiving MIDI commands, the GT-1000 essentially allows you to virtually mirror any or all of the functions that you would assign to a footswitch on the unit, using an external MIDI controller. […] you will be able to set the CC# for whichever footswitches you want to remotely activate.”
As I understand this (not a native speaker), it should be possibel to emulate or ‘mirror’ an actual physical switch by MIDI (‘pressing’ a switch by MIDI not by foot). I know for sure that this is possible with the Boss 500 series FX, because I managed to programm “Tap Tempo” on the RV500 and DD500 using this method. I’ve had no luck with the GT though.
Can anyone confirm that this is possible in the first place? And if so what am I doing wrong?
