In the front of every ski there is a curve similar to a decay envelope. Skis module has two channels A and B and each of them consists of a decay envelope with knob control and a VCA.
There is a TRIGGER input to trigger the envelope, a buffered envelope output which is normalised to the CV input of the VCA. Than there is SIGNAL IN and OUT of the VCA. There is also a CRUNCH switch which activates a special mosfet lo-fi VCA circuit inspired by designs of Standa Filip. This adds a slight crunchy character which changes with the decay of the envelope. A typical application of Skis is to take two signals (noises for example) and generate drum sounds with adjustable DECAY from them with a TRIGGER signal. However, you can also use the two VCAs and two DECAY envelopes independently.
