I did qualify the soundcard remark by saying "IF ...repeating waves" .
Obviously they are pseudo random control sequences.

You need a front end for that thing. For instance, a pass of length X,
by height Y, would need a specific sequence set. Add variations for the
other control lines (whatever they signify), and a cpu will trot that
table out fairly quickly. Even a pic running assembler would do that.
But when you talk about tuning it up by hand, I feel there's more twists
to this than I have a handle on.
