RM4 MIDI

[Mr_Clean]

Hi All, I am planning on using my Ground Control with the RM4. I notice in the RM4 MIDI manual that the Ground Control has 6 Control Change locations available to it in the RM4 - I understand 1 -4 for the 4 modules, do the other two Control Changes switch the 2 RM4 FX loops in & out ?

thanks
