[PlanetCCRMA] pd alsa jack midi

[Tim Moody]

OK.  I'm getting a little closer.  I know from verbose mode that pd is trying:

device 1: tried /dev/midi READ/WRITE; returned -1
device 0: tried /dev/midi00 READ/WRITE; returned 6 (this is the only 
/dev/midi* device that I can cat without a 'No such device' error, but even 
then it returns no data.


In the mean time I learned about pmidi and sfxload from 
http://ccrma-mail.stanford.edu/pipermail/planetccrma/2003-December/003580.html 
(As an aside, asfxload did not work.)
pmidi -p "65:0" 1812.mid actually plays and the alsa patch shows the connection

I tried starting pd with -midioutdev "65:0" and other combinations, but it 
looks like even pd -alsa only tries the OSS midi devices even though it 
uses alsa audio.

It seems the alsa devices are /dev/snd/midi* of which cat does not complain 
about these

crw-rw-rw-    1 root     root     116,   8 Jan 14 19:01 /dev/snd/midiC0D0
crw-rw-rw-    1 root     root     116,   9 Jan 14 19:01 /dev/snd/midiC0D1
crw-rw-rw-    1 root     root     116,  10 Jan 14 19:01 /dev/snd/midiC0D2
crw-rw-rw-    1 root     root     116,  11 Jan 14 19:01 /dev/snd/midiC0D3


Sooo, are these the devices and do I need a symlink from /dev/midi to one 
of them?
