ARP Omni

ARP Omni 1 Image

Omni Mk 1 (1975-77)

The Omni is an analog synth with preset Orchestral String sounds. It has polyphonic Violin and Viola waveforms as well as monophonic Bass and Cello waveforms. It is split into 3 sections: Strings, Synthesizer, and Bass synth - all simultaneously available. It has traditional and simple VCA, VCF, and LFO controls for contouring your sounds as well as a nice chorus that really thickens up the string sound. It has no program memory.

Omni Mk 2 (1978-81)

ARP later released the Omni Mk 2 (pictured above). It was basically the same machine as its predecessor, except for a few minor enhancements and a cosmetic Orange & Black color-scheme upgrade. And it did have a much more advanced triggering system for the VCF and VCA for more expressive results. The Omni has been used by Tangerine Dream, The Cars, Joy Division, Kraftwerk, Trouble Funk and New Order.

I absolutely loathe OMNIs. They sounds fantastic but at this age they require a lot of maintenance. I've restored a few of them and never want to see another again. Buyer beware if you're buying a 'project machine'.

I had an Omni 2 MANY years ago. I remember something peculiar that, to this day, I don't know if it was intended. I could shake mine and create a vibrato. I don't remember ever having another synth that would do that.
