Perhaps because of its complexity, additive synthesis remains rare not just in the modular world but across the synth world in general. Additive synthesis is, as its name implies, the opposite of subtractive synthesis. Instead of starting with harmonically rich waveforms and removing frequencies with a filter, additive synthesis works with the purest waveform, the sine wave, and creates harmonics by adding more sine waves at frequency intervals above the fundamental.

Xaoc's Odessa aims to bring additive synthesis to the Eurorack world. It is, ostensibly, a single oscillator although it does, in fact, produce up to 512 sine waves. If that number sounds large, let me blow your mind — the Odessa is capable of five-voice unison, bringing the total number of sine waves generated to a potential 2560... surely some sort of record?

The various controls housed within the 24HP module are carefully chosen to let...
