If you mean a PC running DOS/Windows, I think you'd need to write a
MIDI device handler for Csound. It's got some real-time output
capabilities (never tried it myself -- too slow a machine), but it
only knows how to deal with MIDI files, not an MPU-401.
But if you run Unix, this should be easier. Write a program that
watches /dev/midiXX and generates appropriate Csound score lines.
Tell Csound to run from stdin, and pipe this into it. (Don't worry
about the translation latency; you have to get the kernel's DAC
buffers down to a reasonable size first.)
In ICMC '96 there are some papers on the MIT group's "Extended
Csound", which does real-time. Apparently the plan is for it to be a
commercial product and run on a SHARC DSP board. (ICMC is
"International Computer Music Conference".)
