  Hi,

 I'm looking into doing some real time MIDI programming with 
 either C++ or Common lisp.

 I would specifically not schedule anything but deliver everything 
 as "play it right now" notes.

 Is it necessary to use realtime scheduling the way JACK does? 
Common Music will do this and it's new variant GRACE:
http://commonmusic.sourceforge.net/cm/res/doc/cm.html#midi-out
(GRACE is actually Scheme)

Real time is desirable with data flow intense audio processing, for 
midi messages (3 bytes per note) the vanilla kernels should be ok, 
as many of the real time improvements have migrated into the kernel. 

Thanks,
Jeff Sandys
