Quad Quantizer: need your inputs

2007-08-26 by Paul Schreiber

A "fallout" of designing the expansion module for the Cloud Generator is a 
nice 4ch (quad) quantizer in a 2U wide panel.

The UI is a 16ch x 2 line LCD with 4 rotary encoders. These select the scale 
for each channel. LCD displays the scale name. For a relatively small price, 
I can add a USB port to allow downloading of your own scales (as long as I 
have people willing to write the host app).

I could aso have 4 pots for transposing the scale (say in 1 semitone steps).

And, there could be a "cascaded S&H mode" where there is a clock (int or 
ext) to sample input #1, next pulse #1 is copied to #2, etc ("analog shift 
register"). Maybe that UI is a 3-position toggle with:

QUANTIZE
SH NORM
SH SHIFT

Normal is 4 independent S&H channels (sharing the common clock).

I suppose one could go "nuts" and make a super-PSIM whiz-bang but maybe that 
is later down the road. I want something with less than 1 man-year of SW 
development :)

So, show me you panel mockups/feature list. The LCD is 80mm lond and 35mm 
wide. There are 2 encoders on the top and 2 on the bottom.
