AUDIO FILTERS FOR MANIPULATION

[Jason Hawkes]

HEELLLLPPPP !!!

I am currently building a complex switchable audio filter system 
using CEM 3350 State variable filters and VCA's (SSM or CEM).

I am desperite for any info that may help in designing this filter 
circuit in regards of the CEM chips, good audio design practices, 
things to watch out for, its power supply, schamatics etc.etc.

The circuit needs input metering, switchable filters and a VCA.  It 
must also be stereo compatable.

Any Info will be very great fully appreciated, and I will return any 
Emails if required.

In eager Anticpation
