Both VCOs are switchable between sawtooth, square, and pulse waveforms with oscillator sync, a ring modulator, and pink or white noise. Pulse-width can be modulated manually or with the LFO or the ADSR envelope generator. There is a high-pass filter, as well as a low-pass self-oscillating VCF. The filter can be controlled by either of the two envelope generators, an ADSR (attack, decay, sustain , release) and a simple AR (attack, release) and modulated by the LFO, sample-and-hold, the keyboard, or a separate CV (pedal) input on the back panel.

The Odyssey was the first duophonic (ability to play two notes at the same time) synthesizer. This 37-note synthesizer was made in three versions. The first version was off-white (see photo above), the second (in 1977) was black with gold markings on its front panel. The third (1977 and later), and more common, version was black with orange markings. The third version had an external audio input, a steel frame, and was also equipped with Proportional Pitch Control (PPC).
