Softube DOEPFER-A-101-2
Vactrol LPG Virtual Modular Add-On

OUR PART #  DOEPFER-A-101-2


The Softube Doepfer A-101-2 Vactrol low pass gate (LPG) add a lifelike and organic response and textures to modular synth patches.

Organic, buttery, warm, woody, rubbery, musical, natural, acoustic—these are words that commonly describe the character a low pass gate module can add to synth patches.

A Classic Concept Extended
Originally, the low pass gate is an invention by legendary synth pioneer Don Buchla. Doepfer has expanded on the concept by adding clever features, not least the Resonance control which can add anything from a subtle nuance to screaming resonance, and further into self-oscillation.

Vactrol Control
The hardware Doepfer LPG modules are based on vactrols, just like opto compressors. The response time of these can vary wildly, which is part of the LPG charm. Softube's plug-in version of the Doepfer LPG adds the Vact switch which is not part of the original hardware. This lets the user select between a fast, medium or slow response time, to cover the variation between individual analog units.

Expertly Made Presets
The release includes over thirty new and inspiring presets that puts the Doepfer LPG to excellent use in your Modular rack.

Softube DOEPFER-A-101-2 Features:

  • Vactrol control of a 12 dB low pass filter and a voltage controlled amplifier
  • Switch between three different sets of vactrols—slow, medium and fast
  • Auxiliary control of output mode (Low Pass, LPG or VCA mode) via the G1 and G2 inputs
  • Requires Modular
