Mk V Head with a Boss GT 10

[Ghtransam79]

Hi all,
Ive recently got a Mk V Head and cab and a G lab midi amp controller, ive set it up so it changes the channels via midi, but cant seem to make it turn the solo boost on/off.
I have got it to work via the amp control on the gt 10 but was wondering if it is possible via the midi amp controller if you get what i mean, im not great at understanding midi.
Just wondering if any of you guys use this or a similar set up, and could offer any advice.
Getting some fantastic clean sounds with it.
Cheers guys
