[Sugar-devel] Sugar 0.92 MIDI Controller Issue

[Art Hunkins]

Thanks, Peter; I will continue this thread with the dev group as you 
suggest.

To respond to your question:

The command line you asked about returns nothing - when run either before an 
activity (involving MIDI) is opened, or after the activity is closed.

The file "midiC1D0" does exist however, though with my rudimentary knowledge 
of Linux, I've no idea what kind of animal it is. I just know it's not a 
directory, and prints nothing with "cat midiC1D0" (from the appropriate snd 
directory).
