FEG aka Flexible Envelope Generator by Rides In The Storm is a full-featured ADSR envelope with some special features. The four-stage envelope has a very percussive characteristic, which makes it ideal for fast sequencer triggers and very dynamic modulations. Two time ranges (fast / slow) can be selected manually and via control voltage. The module is triggered via gate voltage or the trigger button. In addition, the envelope can be set to loop mode, which is similar to an LFO with a variable waveform. A separate OneShot-Mode is also planned. In addition to the normal CV output, there is a CV output with an inverted voltage.
