Unique and fragile

Its sound is unique, it sounds as a well known one. The build is quite fragile: the pushbutton switches are highly prone to break and no replacement does exist. The tantalum capacitors that control keyboard voices are failing quite often, so it's mandatory to replace them all. The power supply had a design error that could burn the other electronics upon power-up. And the bass line is lowest-key priority, so that the old keyboard contacts usually have bounces that switches continuously between held notes... The ensemble/chorus unit is a genial creation by dutch company Eminent: three BBDs in parallel, clocked with 3 unsync'ed LFOs, and no straight signal, does create the ethereal sound the instrument is famous about. The term "synthesizer" is improperly used with the Omni: indeed it's paraphonic, with a single 24dB/oct VCF (the famous ARP 4075) and the ADSR is first-note triggered. The Omni II had an extra button to allow repeated triggers and a separate bass line EG and output.

Best String Machine + 1VCO poly synth

Amazing string machine. Synth is good for bass lines and just whatever. The only problem is that the fine tune knob lives on the bottom and needs a screwdriver for adjustments. Joy Division Atmosphere and 'Love Will Tear Us Apart', New Order 'Blue Monday' and 'Age of Consent', The Cure 'Just Like Heaven'. It's that classic strings sound.

In this interview, Stephen explains how he was drafted to play keyboards instead of his usual drums on certain New Order songs. "Did I want play keyboards? I'm the world's most reluctant keyboard player, I didn't really want to but it happened early on because there was just the three of us. It just happened that Bernard can't sing and play guitar at the same time, Hooky can't sing and play bass, and I just can't sing playing anything! So I ended up playing keyboards. We got the ARP Omni towards the end of Joy Division for Closer after using an ARP Solina earlier. So I ended up playing that with the drum machine on top."

Another big-time keyboard in The Cars early records was the ARP Omni, which is what Greg used mostly for the "strings" type sounds (String Synths were huge in the late 1970's). If you listen to songs like "Moving In Stereo", "All Mixed Up", "It's All I Can Do", "You Wear Those Eyes" - you can really hear that ARP Omni in full effect providing the wash of strings in the back.

The ARP Omni is visible below the MiniKorg 700S during the solo on Moving in Stereo during the clip. It is also visible in a LOT of other early Cars live footage.
