About this module

BLM ACID n SONS FILTER

WIDTH: 6HP

CURRENT: +64mA -64mA

24DB VCF + VCA

This module has the modern 3109 filter chip. The older 3109 chip is found in the vintage Roland keyboards like SH-101.

What I did is add resonance audio drop out compensation and precision resistors for the exponential converter. The module

will easily track 5+ octaves when in full self oscillation. Band pass was also added as a bonus. The band pass steals the

show, as many have not heard an sh101 with band pass.

-24db low pass

-18db band pass

-Internal VCA for easy voice building

-FM Bi Polar CV input for the Filter

-Envelope Input for the VCA

-Dual Audio Inputs, one direct, and the other with over drive.
