What Modular Add-On: Doepfer A-101-2 Vactrol LPG does
The plugin reproduces the Doepfer A-101-2 low pass gate, which combines a 12 dB low pass filter with a voltage controlled amplifier. Response time is set by a Vact switch, which Softube added and which is not part of the original hardware, so the user can choose between fast, medium and slow response, covering the variation found between individual vactrols. A Resonance control, which the developer says extends the original concept, is included. Over thirty presets are supplied with the release.
