Subject: 
 ---------------------------------------------------------------------- Added
 Karl Kurbjun's sound output patch, cleaned up some output. Main file is now
 midiplay.c, midi2wav is still in there for anyone who wants it. Set sampling
 rate to 22k, and increased note decay time. Reduced number of concurrent
 active voices and made new notes replace used voices if none are available.
 This makes lag less apparent. I really hope this wont go red. (turns around
 and runs)
