Re: Deffective BBD Module? (4096 Stages) and Extremely High Resonant Noise

2006-12-29 by regimental1200

If memory serves me well, I followed the manual one time and used its 
CV output to control an LPF...forget if it gave me the result i 
wanted.  I'll try again and see if there's a difference from having 
the filter controlled by a seperate envelope.  Thanks!
