Hmmmmm.......

The reason I posted the faceplates was to get some input on 
potential modules, not to frustrate people. I have already gotten 
some great feedback on how to "fix" some of these designs and 
move them up the "possibles" list. There is no plan to produce 
them IN THEIR CURRENT FORM.

For instance, the comb filter module has the problem that 
moving filter frequency inside the comb, doesn't produce very 
interesting results. The comb start point and spacing is 
significant, but spacing inside the comb is relatively 
uninteresting.

Chris Curtis was kind enough to point out the similarity to a 
resonant equalizer and suggest making the F2-F7 controls into 
volume controls. This seems very obvious in retrospect, but 
represents a 90 degree turn in my thinking.

The module comes from research intro a "cepstrum" or second 
order FFT. The original name was "Cepstral Processor" but it 
wouldn't fit on the faceplate. The ear does seem to do a second 
order FFT on sound, and use that data for spatial location.

So the purpose of the module was to give independent access 
to cepstral parameters, which has not been done before in a 
single module. The "spread" control is a "quefency" control in the 
cepstral domain (all the cepstral terms are respellings of 
frequency domain terms).

Coming at it from this abstract mathematical point of view, I 
completely missed the connection to resonant equalizers.

So this discussion has already produced very positive results.
