MIDI guitarists! I just got the GR-55!

Maybe you can help me out, as i am a newb to Midi.

I want Cubase 5 to send patch change and looper control signals to the GR-55. I hope to use Cubase as a click track manager for a live band situation and then control the looper and patches on the GR-55 so I can stay in tempo with the click perfectly and automate patch changes (playing prog is hard enough without the feet being involved).

So I have a laptop, Cubase 5 running with my click track, I have a UM-One USB-Midi converter attaching to the GR-55, and then I am lost. If you could walk me through how to have cubase enable / disable the GR-55 Looper and send a patch change at varying time points in the track, then I will be set.

Thanks,

Gorden
