[CM] Receiving from portmidi

[Rick Taube]

i have MIDI input working again in Portmidi -- somehow I managed to  
lose several function definitions in the file cm-recv.lisp. I put  
these back and tested on SBCL and OpenMCL (on macosx, I will also  
test on my planetccrma box tomorrow when im at work but it should be  
working.)

Ive uploaded the fixed portmidi tarball to sourceforge as  
portmidi-2.0.2:

http://sourceforge.net/project/showfiles.php? 
group_id=9766&package_id=172088

my apologies for getting behind on the fix...

also Scheme MIDI hooks should be working in Grace sometime this week,  
at that point I would suggest trying that for midi realtime in lisp  
as the support and scheduling will be better.
