[SoaS] Sugar 0.92 MIDI Controller Issue

[Peter Robinson]

Hey Art,

Firstly. Can you make sure you send these to SoaS mailing list and not
direct to me. It allows others to see the problems and possibly help.
I'm on the list so I'll see the mails.

It looks like its seeing the device:

> ALSA lib rawmidi_hw.c:233:(snd_rawmidi_hw_open) open /dev/snd/midiC1D0
> failed: Device or resource busy

It looks like the device is already in use.

if you do "lsof /dev/snd/midiC1D0" what do you get?
