XOAC Devices Odessa is a - wait for it - Variable Spectrum Harmonic Cluster Oscillator. An interesting FPGA based module. Edd takes us on a 5 Minute journey through it's sonic landscape.
It uses the principle of additive synthesis controlled by a set of carefully tailored macro parameters to harness thousands of sinusoidal partials that altogether form the resulting sound. The series of harmonics can be squeezed or spread apart, tilted, and pruned by a comb-like frequency response, resulting in a variety of unearthly sounds. Furthermore the VCO provides Through-zero linear FM and detuneable clusters of up to five voices.
