I'm not sure what you're getting at here.

I think Richard's point was that, except for equal temperament,
there is a limitation in using only 12 tones in a scale;
namely, you can't differentiate between, say, a sharped fifth
and a flatted sixth.  We normally think that G-sharp and A-flat
are the same, but "it ain't necessarily so."

Is anyone aware of any freely available Ada packages that can be
used to mess around with a sound card on a Win98 or Linux/Intel PC?
