Cubase 6 and EuCon - How to program the grouptracks


Having an AVID mc control v2 and like to use one button in the touchscreen to enable/disable the Cubase 6 group tracks.

In more detail:
In Cubase 6, I have some guitartracks within a grouptrack “GUI” and like to select the SOLO/MUTE function in the group track.
(All the single tracks are displayed and can be managed easily)

Could not find any function in the mc control v2 “tracks”-tab to do this. :question:

Any ideas?
