MS20 VCF

MS20-VCF clone based on BartonSynth version.

2 filters in one with a possibility to bridge them and get a band pass filter.

When using the band pass mode, signal IN on filter 1 and out on filter 2.

cutoff + resonance, with a switch to chose low pass or high pass mode.

CV control on the filter cutoff.

Self oscilation if resonance pushed to maximum, can be adjusted with 2 trimmers :

You’ll find the schematic of this module below:

Uses an SMD LM13700 because the DIP ones are not produced anymore.

Regular build, I use ceramic capacitors but you can use film/polyester.

:warning: When building modules, always do it in this order (from smallest component to highest):

For the next part, always place them without soldering them on:

Once placed, put in place the front panel, then fasten all components to it. Once this is done, you can solder them.
