I stumbled on a site that may be of interest to Macintosh users.  I was
poking around doing a search on "harpsichord", and found an operation in
Seattle that sells kits of various obscure & folk instruments.  Anyway,
they had a page with a number of shareware and freeware programs for
displaying oscilloscope functions on your Mac, as well as frequency
counters, sound file playback applications, and sound editors.

The address is http://wwwhost.ots.utexas.edu/mac/pub-mac-sound.html if
you're interested.  I know this is on the fringe as far as AMI goes, but
it seems to fit some of the threads we've had lately.
