What's up with Nyquist under Macintosh OS X?

I can't get Nyquist functions to work on my PC, e.g. OSC is undefined.

I have tried to play existing files (some rather large) and have had the computer take an inordinate time to play the file. It started out ok and then got choppy and choppier and then very long delays til the file finally finished.

Nyquist runs under OS X. Nyuquist for OS 9 is no longer maintained.

See the Nyquist Manual (Online) about installation, esp. the part about adding a search path to the registry. This should not be a problem if you use the installer.

If you load a large file, assign it to a variable, and then play it, the sound file will be converted to in-memory samples. If you just call 

         (play-file "filename")
or 
         (play (s-read "filename"))
this should not happen. Also, if you are computing something and can't keep up, you can type 
        (sound-off)
to turn off real-time playback, and then type: 
        (r)
to hear the sound when computation is finished. You can call (r) anytime and as often as you wish after a computation has finished to (re)play what you just computed.
