string filter bank (was: Re: [sdiy] 40-band vocorder)

[David G. Dixon]

Man, that thing is fantastic!!  The vocal stuff is cool, but the tuned
resonant noise is what has me all excited.

One question, though:  Am I the only one who thinks that this would have
been a perfect candidate for a panel PCB with PCB mounted hardware and pin
connectors to reduce/eliminate the extensive panel wiring?  Would using such
a PCB compromise the quality of the sound in some way?
