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

I've got a GSP-2112 upgraded to GSP-2120 v2.11 and I'm trying to edit using RPEdit using 
Windows 2000 and a Midex 8 interface. Everything is working except that about one time in 
three the RPEdit reports a bad midi header and hangs making the system unuseable. The 
usb-midi hardware all works perfectly on a Mac running cubase so the hardware is OK. I just 
unplug the usb from the Mac and put it into the PC. Is there anything different about a 2112 
upgraded to a 2120 or does Windows 2000 have a problem with Midex 8. I would happily buy 
a cheap midi interface for the PC dedicated to the 2112/2102 if this is the problem.

 Any thoughts gratefully received. Its a case of so near yet so far. Thanks in advance
