VCA

VCAs are another critical component of a Eurorack system. If you haven’t already, you’re going to hear people say, “You can never have enough VCAs”. So why is that?

If you’ve used a fixed architecture synthesizer, you might be familiar with VCAs already. It stands for Voltage Controlled Amplifier, meaning they use a voltage signal to control the amplitude, or volume, of another signal. The most common way that they’re used, and the way that you see them implemented in fixed architecture synthesizers, is to control the volume of the final sound produced by a synthesizer using an envelope as the control voltage. You strike a key and the ADSR envelope of the VCA determines if that note will swell in slowly or hit abruptly, and if it will end as soon as you release the note, or ring out afterwards.

While this is still a common way to use them, in a Eurorack scenario VCAs can be employed in a number of different ways. It’s important to stress that a VCA is using one signal to control the amplitude of another signal, and that doesn’t mean that it always has to be a CV signal doing the controlling, or that it has to be an audio signal being controlled.

VCAs are helpful to shape modulation signals with envelopes. This can let you ease in an LFO to modulate pitch or filter cutoff with a slow attack. Or if you used a slow LFO to modulate an envelope, you could make your envelopes get slowly bigger and smaller. By using gates to open and close a VCA, you can mute and unmute CV signals to toggle their effect on and off.

Amplitude modulation is a technique where audio rate signals are used to control the amplitude of another signal. For example, by fluctuating the amplitude of a sine wave faster than the frequency of the sine wave, the wave shape begins to change and new harmonics are introduced.
