Compiled with unofficial version 3.54.0.0c source tree with no problems.
This command-line:

  csound --sched -i devaudio -o devaudio fullduplex.*

works great. I've got full-duplex from Csound but not without
intolerable latency. Nice work, Steve.

Btw, I'm using the OSS/Linux drivers for a system including an MQX32M
MIDI interface, a SoundBlaster AWE64, and a SoundBlaster PCI128. I
tested the examples only on the PCI128 so far.

I also tried this:

  csound --sched -i devaudio -o devaudio -M /dev/midi01 full-midi.*

If I'm correct about its operation, I hold down a MIDI key, speak into
my mic, and altering a mod wheel will do a frequency sweep. Right ?
Unfortunately my testing keyboard is a Casio CZ101 with only a
pitch-bend wheel (no mod). I tried using the 'pchbend' opcode but it
didn't seem to do anything. I'm probably missing something and will keep
hacking.
