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

Hi guys,

could anyone explain how I can change programmes on my GSP2101. 
Let´s say I want to change programmes on MIDI-channel 7! What kind 
of settings do I have to do?

PROBLEM: I already tried to send PC messages on channel 7 but 
nothing´s happening?! First of all I thought the MIDI In was broken 
but I also connected a MIDI cable from the GSPs MIDI-Thru to another 
MIDI device and it works! So the GSP must receive MIDI-information 
but, again, there´s no programme change on the GSP.

Any suggestions would be greatly appreciated!
Chris
