Vostok Instruments Ceres

If you have been already into the Eurorack world for a while, I’m sure you have heard the sentence: “you never have enough VCAs” more than once.

As an electronic musician, this has always been present. I can’t count how many times I needed an extra VCA with all of them already being used.

I wanted to create an all-around, good-sounding, and handy VCA, small enough to fit on little systems but with a good amount of channels and functionality. And this is what Ceres is.

Its core, the 3360, has been used for years in dozens of devices with remarkable performance. Sum it to a carefully designed 4-layer PCB layout, and we get a super quiet VCA in terms of noise and CV bleeding.

The combination of daisy-chained inputs and mixed outputs achieves a vast range of possibilities. Several CV signals can modulate a unique source with every output mixed back at the final stage to create new waveforms and open the door to experimentation.
