Modular Add-On: Doepfer A-101-2 Vactrol LPG

This product is an expansion for Softube Modular. If you do not currently own Modular, you can purchase it HERE.

Ever since the low gate pass was invented by Don Buchla, low pass gates have been heralded for their ability to add a lifelike and organic response and textures to modular synth patches. Doepfer A-101-2 Vactrol LPG adds this and more to your Modular 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.

In Short:

• 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 

System Requirements

• macOS Big Sur 11, Monterey 12, Ventura 13
• Windows 10 (64-bit), Windows 11
• Softube account
• iLok account
• Computer with AU, VST, VST3, and/or AAX-compatible DAW host software
• Internet access (for downloading installers and managing licenses)

Supported CPU Families 

• Apple macOS computers with Intel Core i3/i5/i7 or Apple silicon (M1 or newer) CPU. Apple silicon is supported natively. 
• Windows computers with quad-core Intel Core i3/i5/i7 or AMD quad-core processors with SSE 4.2 support.
• Other Intel processors (Celeron, Pentium, and Xeon) are compatible if they support SSE 4.2 instructions. 

Supported Host Software (DAW)  

Any 64-bit VST, VST3, AU, or AAX (Pro Tools 11.0.2 or higher) compatible host application should work. However, due to plug-in host differences between DAWs—and our rigorous standards—Softube only officially test their plug-ins and instruments in the most recent versions of Pro Tools, Logic Pro, Cubase, Ableton Live, Studio One, and Reaper. Softube plug-ins are not tested regularly in non-listed systems. They will likely work if the system requirements are met. However, the manufacturer cannot guarantee a solution for issues in unsupported systems. 
  
Softube strongly recommend using VST3, as some of their plug-ins have features that are not present in the older VST format. Supported sample rates: 44.1, 48, 88.2, 96, 176.4, and 192 kHz, in both mono and stereo. The most recent maintenance release of your DAW application is recommended. AAX DSP is not currently in active development. TDM/VENUE/RTAS are no longer supported. See Legacy Installers.

• Softube Modular is required to run this software.
• Make sure that you always use the latest iLok License Manager. It is not included in the Softube installer but can be downloaded from www.ilok.com​
