dual decay + vca
In the front of every ski there is a curve similar to the 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 lofi VCA circuit inspired by designs of Standa Filip. This adds a slight crunchy character which is changing 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.
