The ARP Odissey is a two-oscillator analog synth, and was the one of the first synthesizers with duophonic capabilities (the ability to play two notes at the same time).
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 (static) high-pass filter, as well as a voltage controlled low-pass self-oscillating filter.
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 Sample/Hold input mixer can be used to route the output of the VCOs to the FM input of VCO 2 and the VCF, enabling audio.
