Hi there:

Thanks very much for your help. I have got it working now:) Just one minor
minor problem. I now can start pd with midi like this:

Pd -mididev 2

But when I add "-mididev 2" into the .pdrc. Pd won't start with the right
device, it goes back to -1 as if I have not specified.

Is there a other pdrc file that has higher priority then my .pdrc?
