The ARP Omni was a simple electronic keyboard which produced preset string sounds. It was ARP's best selling keyboard.

The Omni, ARP's best-seller, was an analog synthesizer with preset Orchestral String sounds. It had polyphonic Violin and Viola waveforms as well as monophonic Bass and Cello waveforms. It was split into 3 sections: Strings, Synthesizer, and Bass synth - all simultaneously available. It had traditional and simple VCA, VCF, and LFO controls for contouring the sounds as well as a chorus that thickened the string sounds. The Omni had two oscillators per voice as well, but there was no program memory. It was a revolutionary electronic instrument in its time.
