Mailist to discuss all issues regarding the Digitech GSP-2101 Guitar FX Processor

Hi,

maybe someone can help me out with this: I´m controlling up to eight 
MIDI-devices with my footcontroller (similar to GCX Ground Control 
Pro).

I chose MIDI-channel 7 on the GSP2101 but the GSP is not responding. 
I tried different MIDI-channels (1,2,3,..., ALL) without any luck.

Does anyone know what I´m doing wrong?!?!

I hope that the MIDI IN-jack´s not broken!

Thanks a lot!

Chris
