Dual Slew Processor
The EMW dual Glide Processor module can create glide or portamento effects on control voltages. A common use for this module is to put it between your MIDI to CV interface / sequencers and your oscillator(s) to create portamento effects on the note, however it also can be use on many other situations where you want to modify the decay characteristic of a control voltage or another low frequency waveform.
