Hi Jürgen,
   great idea!

Another thought came up recently:
In November during the course of the Wien Modern festival here in Vienna
( http://wienmodern.at ) I had a chance to see and to listen to the east
german Subharchord.
This particular piece of ancient technology provides a subharmonic
divider (down to 1/29) and a MEL-Filter bank.

I understand that this is way too big for your intended project, but did
you ever consider recreating (the original is based on LC-circuits) such
a filter bank?

To me it sounded very distinctive and colourful.

(sorry, just german language with some diagrams)


just asking,
     :-) Michael.
