I've just built a "Cedar Sound Digitizer" which is supposed to be fully
compatible with Farallon's "Mac Recorder" sound digitizer, and I'd like
to send it simple commands from Macintosh Allegro Common Lisp. Basically I'd 
like to tell it to start sampling, to stop sampling, and to save the captured 
sample to a file.  I know that there is a package called "MacRecorder 
Hacker's Toolkit" which allows such commands to be sent - but the code is all 
in C and assembly. I suppose I could go the foreign-function-interface route, 
but I'm not sure how and I'd rather not. So I'm looking for access to 
the digitizer from within Lisp.  If anyone has digitizer-related MACL code, 
or any other hints that might be useful, I'd really appreciate hearing from 
you.

 Thanks!  -Lee (spector@cs.umd.edu)
