Gary Chang wrote to me with some very useful suggestions to improve
the musical usefuless of the analog shift register program that I
posted a couple of days ago. I incorporated his ideas in a complete
rewrite which I've just posted as gc-sah-sr-qua.bas. Basically, it's
now a 16-stage delay line with four variable taps. I had wanted to be
able to change the taps interactively, but it turned out to be very
diffcult to set them accurately. So for now, you just change some
constants in the program source and click the 'program' button.

Give it a clock pulse on the START input and a varying voltage on IN-1
and out come four semi-tone quantized outputs at different delay
times. The AUX output is pulsed synchronously with the incoming clock,
but it needs to be buffered to be useful; I couldn't get my 2600 EGs
or the DSC to trigger on it.

Many thanks to Gary for making his suggestions!
