APC40 question

Hi all

I'm on the verge of another new-gear spasm. Before I jump for the APC40, I'd like to know how it deals with group tracks.

I know you can't move the hardware controls to control the return tracks, but I assume you can move along the group 'masters' in the clips view? If the group tracks are 'expanded', will the APC40 select those separate tracks too?

Hope I'm making myself clear. Thanks.

Should have Googled. From Ableton -

"How will group tracks be handled?

If a group track is closed, the fader controls that group track. If a group track is expanded, the faders next to the group fader control the sub faders. "
