The Omni was single-oscillator in nature; normally, the String section alone was processed through the on board, patented ARP 3-voice Chorus Phaser circuit, producing the lush, moving sound the instrument is most known for. However, the Synthesizer section was processed through this circuit when a front panel "Chorus Phaser" switch was activated, simultaneously summing the String and Synthesizer section outputs and slowing the Chorus speed.

2-pole, Low Pass Filter and preset Attack Decay
Release (ADR) envelope generator. A Staccato switch controlled the Bass section's envelope contour Decay time vs. the original Omni Bass voice ADSR assignment via its Synthesizer section. Further, the Omni-2 Bass section had its own audio output on the rear panel in addition to the Strings and Synthesizer outputs; separate amplification of these three distinct outputs was referred to in ARP literature at the time as "Tri-phonic". The Omni-2 also featured selectable Single- or Multiple-Trigger keyboard control of envelope contours and re-branded the original Waveform Enhancement panel control switch as "Hollow Waveform".

The Omni was very popular in its time, as it was amongst the first available polyphonic electronic keyboard synthesizers. Examples of the capabilities and sounds of the Omni can be heard in recordings such as "Good Times Roll",
