The electro Cardiogram VCF/VCA is a diode ladder filter design like the filter in the TB303. Frequency central modified their Vogue VCF/VCA design to use diodes instead of transistors in a 24db/octave lowpass filter. There is a VCA built into the module as well and the output of the VCF goes into the VCA. The diodes used are 6 LEDs, so as the filter cutoff is turned up the LEDs get brighter and you can see them through the red translucent panel.

There are two audio inputs with attenuators that go into the filter There is a output directly from the VCF as well as an output from the VCA. There are control knobs for cutoff and resonance. There are two CV input jacks, one goes through an attenuator and then to the filter cutoff, the other goes to the VCA at full strength and then through an attenuator to the cutoff, so with one envelope you can open the VCA and open the filter an adjustable amount.
