Vox Tonelab SE as foot controller for MainStage 2.

Hi,

I am completely new to MIDI. I'm a guitarist and I want to use a Vox Tonelab SE (which I already own, as well as a Roland UM-One MIDI interface) to control Mainstage 2.

What I'm asking is if the Tonelab is ready to change patches as well as changing fx (turning stompboxes on/off individually), or will I have to buy a new foot controller?

Mainstage seems really easy to use, but I am not getting any results.

Thanks in advance,

Jorge
