ADDAC 601 - Fixed Filter Bank

The ADDAC 601 - Fixed Filter Bank is still unbeatable when it comes to tonal complexity - thanks to the dedicated envelope followers after each frequency band, you can create a spider-web of spectrum-based modulation!

ADDAC 601 - Fixed Filter Bank 

Our ADDAC601 Analog Filterbank will have you shaping the spectrum of your sound "tout de suite".

With its 8 fixed frequencies, this very special filterbank has two additional features that you won't find anywhere else. Each of the 8 band volumes can be controlled through a linear high performance VCA, which adds great dynamics and new abilities to the art of filtering. Additionally this module also doubles as an envelope follower, with a dedicated CV output per band.

It features numerous output options: you can select between individual bands, the full processed sound, a wet/dry signal and even choose between odd or even frequencies.

Plus you can add up to two different signals, which are mixed internally by the ADDAC601 inputs.
