Gotharman's Dual Band SSI filter board for Anamono X and Xmini
Dual Band SSI Filter. Four 24dB resonant filters, two that are switchable between HPF and LPF modes and two that are always in LPF mode. This gives four resonant peaks, and makes this filter ideal for formant sounds. It is also great for bass sounds and a lot of other sounds. It is based on a bunch of the new great SSI2144 filter chip.
It is organized as two chains of HPF/LPF + LPF in series. The two chains can be connected in parallel or serial to each other, and they output to each of their filter output.

Please see the Anamono X / Xmini user manuals on details how to install this.
After installation, you must set it up in the menu's, in order to make it work properly.

On the VCF pages, you will now be able to view and adjust the appropriate parameters.
On Anamono X:
HpCut: HPF/LPF 1 and 2 filter cutoff frequency. Space between the 2 filters can be adjusted with Space.
LpCut: LPF 1 and 2 filter cutoff frequency. Space between the 2 filters can be adjusted with Space.
Reso: Filter resonance of all 4 filters.
Space: Space between the cutoff frequencies of the two filter chains.
HPF2: HPF2 filter mode HPF or LPF.
HPF1: HPF1 filter mode HPF or LPF.
Conn: Connection of the 2 filter chains. Ser (serial) or Par (parallel).
Out1/2: Mix between filter output 1 (HPF/LPF + LPF chain 1) and filter output 2 (HPF/LPF + LPF chain 2).
