Details

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.

Features

  • dual decay envelope with adjustable decay time (trigger input, CV output)
  • dual vca (signal IN, signal OUT, CV IN is normalized to CV output of decay envelope)
  • crunch feature inspired by circuits of Standa Filip
  • jumpers for changing the decay envelope to release envelope (vca is on full while there is a gate signal and than it decays)
  • jumpers for enabling the decay knob to completely mute the decay envelope
  • jumpers for selecting weird filtering of the output signal (also inspired by Standa Filip)
  • front panel from oak wood, handmade custom knobs
  • handmade in Brno, Czech republic

Fun build!Review by Andrew
I'd say this was a very fun beginner-intermediate build received it with fast shipping and assembled in an evening! :) (Posted on 1/5/2016)
