Do you actually have devices available?
try doing:
(pm:GetDeviceInfo)
and see if portmidi thinks you have active devices. For example on
my machine I get:
? (pprint (pm:getDeviceInfo))
((:ID 0 :NAME "IAC Driver: Bus 1" :TYPE :INPUT :OPEN NIL)
(:ID 1 :NAME "828mk2: Midi Port" :TYPE :INPUT :OPEN NIL)
(:ID 2 :NAME "IAC Driver: Bus 1" :TYPE :OUTPUT :OPEN NIL)
(:ID 3 :NAME "828mk2: Midi Port" :TYPE :OUTPUT :OPEN NIL))
If getdeviceinfo returns nothing, then use /Applications/Utilities/
Audio MIDI Setup.app and add them (quit lisp first). Sorry im not
sure what to do on linux...
If getdeviceinfo returns a list of devices then its a bug in CM,
please send me your list of devices.
