Are you sure hw:1,0 refers to your GR-55? Check the entries in /proc/asound/cards again, please. > Using Logitech Webcam software I can record the guitar output; Using Cheese, I do not get Audio.

For Linux, use amidi. "amidi -l" will list all available MIDI ports. For example to dump all incoming messages, use "amidi --port hw:X,0 --dump". And to send messages, use "--send-hex" and make sure you send valid MIDI messages, otherwise the other side won't do anything. > I'm going to keep on this till I get it 100%; I have patience; lets hope you do too. Well, I believe the quirks patch is correct, and there's only software configuration issues left. Daniel
