A simple and affordable module with countless uses

Zoë, 07.03.2014

This small, unassuming module is useful for all sorts of things. The trick is to think as laterally as possible, which is always good advice when using a modular synthesiser.

When feeding it a slow gate, such as the accent from a TB-303 style step sequencer, you can make certain notes have quirky features. For example, most notes can go through a filter's low-pass mode, while accented ones go through its high-pass mode. Or most notes can be square waves while the accented ones are sawtooth waves.

But the distinction between a control voltage and an audio signal is arbitrary. Audible, even tuned square waves can be thought of as very fast gates. So using an oscillator's square wave output, you can alternate between waveforms and filter types and anything else you can imagine so fast that you can play a melody on the alternation itself, making bizarre new waveforms in the process.

Indeed, using nothing more than an A-110 and an A-150, you can create waveforms that are, say, sawtooth for the first part of the cycle and triangle for the second part, with the pulsewidth dictating when the switch occurs. That's pretty West Coast for such an ostensibly East Coast synthesiser.

I'd recommend this module to anyone who likes thinking laterally, as it can add new dimensions to even the simplest of other modules.

Good low cost cv switch for eurorack

J Synth, 04.12.2019

It is useful for switching between cv signals in a eurorack system, with a surprising amount of uses. A small module, but benefical noetheless.

Nickel pour du contrôle de CV.
Pour de l'audio, ça marche mais pas de buffer donc quelques glitches ou clicks lors du changement de circuit.

Simple to use Switch

vurt, 18.11.2017

This a great no-nonsense and simple to use dual Switch. I use it to switch between waveforms on a VCO or to switch stereo samples on a Disting (e.g two different drum sounds in each channel, CV into the Switch varies between the two samples).
I'd not use A-150 as the only Switch since it's functionality is a bit limited especially in comparison to something like A-152 (which is a lot larger).

Overall you can't go wrong with this module and it's simple to find uses for it in most patches.
