Features
- This is a diode ladder VCF - original design by Moritz Klein, with a couple of small adaptions made by T Killa
- There are two CV inputs
- CV1 with an attenuator to control the amount
- CV2 with an attenuverter so it's possible to invert the signal as well as controlling the amount of modulation
- The filter is a low-pass filter only
- 3U tall
- 6 HP (30mm) wide
- Uses ER-PROTO-02 controls cards
