Doepfer A-101-2 Vactrol Lowpass Gate
- Order number: 120070
- Depth: 50
A classic function for organic sound in Eurorack synthesizers: the A-101-2 Vactrol Lowpass Gate from Doepfer.
Lowpass gates are a concept from Buchla synthesizers and make up a large part of the sound of these instruments. Typically, a lowpass gate consists of a lowpass filter and VCA, both of which can be controlled together. Consequently, the overtone content and amplitude are reduced at the same time, which is also the case with many classical instruments. This gives your sounds a natural timbre, ideal for percussion and FM bells.
Unlike other LPGs, the A-101-2 has two CV inputs and two gate inputs as well as a resonance parameter(!). This extends to self-oscillation and allows for wild sound colorations. The A-101-2 tends to sound rather harsh, but can also intervene gently in your sounds.
The two gate inputs let you get the module going without any fuss. You can switch the module to use it only as a VCF or VCA.
A great module that provides a classic synthesizer module in clear Doepfer style.

- Lowpass gate based on vactrols
- Two CV inputs for controlling F/A (filter cutoff and amplitude)

A-101-2 @Doepfer
WIth a long trajectory building synths, MIDI keyboards and designing bespoke devices for music pioneers Kraftwerk, Dieter Doepfer decided to design his own modular synthesizer in 1995 based on existing electrical and mechanical specifications of lab equipment he used during his years at university. The official presentation of the system at 1996 Frankfurt Musikmesse caught everyone by surprise and created lots of interest. After Doepfer published the specifications on his website, many instrument designers and engineers saw the potential of the new Eurorack format. Doepfer continues expanding their catalog of over 200 modules (and counting), operating from their modest offices in the outskirts of Munich.
