Laurentide Synthworks VG2 Eurorack Module - DIY Build
Laurentide Synthworks VG2 is a Passive Dual Vactrol Gate meaning no power is needed to get some awesome sounds out of this eurorack module! Each Vactrol Gate on the VG2 has 1 CV Input (gate, envelope, LFO, etc.), 1 Audio Input and 1 Audio Output. The CV Input hits the Vactrol LED, allowing whatever audio to pass through.
In addition, there is a simple Low Pass Filter applied to the Audio Output with an amount (i.e. Cutoff) knob. As this is a passive circuit, it will not give you full cutoff control, but it does allow the calming of brash wave shapes. There is also an LED at the CV Input for a quick visual reference of the incoming signal.
Keep in mind that a passive circuit using a vactrol can cause subtile differences in tone and output sound. One may be slightly “louder” than the other, or one might have a longer or shorter release time. One circuit could be better suited for drums or percussion while the other might process harmonies or sequences more to your liking.
That being said, each vactrol or VG2 is unique in its sound. Being that the Laurentide Synthworks VG2 is available as a DIY kit only, this gives the builder the opportunity to tweak some of the resistors and vactrols and thus making each individual build unique in itself.
