Korg Mono/Poly

Korg MonoPoly Image

A cool analog monophonic/polyphonic from Korg. It has 4 VCO's which can be shared in 4-voice Polyphonic mode, or linked in Unison for a versatile monophonic lead. Each VCO has its own level, tune, and waveform type control. Waveforms include triangle, sawtooth, variable pulse wave. It has a great VCF (filter) section as well as 2 envelope generators (one for the oscillators and one for the filter). There are also 2 individual LFO's which can be used to modulate the Pulse Width, envelope and Arpeggiator independently.

A very flexible and fun synth. Other cool tricks up its sleeve include chord memory and an effects mode in which oscillators have a variety of ways to be synced. The built-in arpeggiator and sequencer can run all 4 VCO's at a time or cycle through each voice per note! There's also portamento, CV/Gate, VCF and VCO mod inputs, white noise generator, and the pitch/mod wheels can be assigned to control LFO, pitch or the filter. Its sound quality is nice and very Korg. This synth is used by Hardfloor, Tangerine Dream, The Orb, 808 State, Juno Reactor, Megaton Matt Haines, Freddy Fresh, and the Chemical Brothers.

Sensational sounds can be had on this baby! Imagine a Korg Trident devouring a Poly Six and then for dessert adding in a Korg Sigma! This will give you a little idea how crazy these synths can perform and sound.
@iambic9 I got mine in perfectly working order for under a grand! The Mono/Polys regularly sell in the $1000 - $1400 range. Obvious that you have an agenda to bump up the prices which is really a shame and should not be tolerated. Once in a while somebody will ask something closer to $2000 for one but those just linger and linger and linger and NEVER sell!
Great synth regardless.

P. from Chromeo says that this is one of his favorite and most used synths. It's used for monophonic leads on many of their songs.

The "estimated value" should be updated on the page. I've seen "as-is" units selling for $1,600. In working condition I see them selling anywhere between $2,200 to $3,200 on ebay. Don't rely on the information here if you are buying or selling.

This is y all time favorite synthesizer. I don't have a real one, but the Korg Legacy Collection (2007 analogue edition) has this built in and it's very faithful to the original sound from what I can tell.

I personally prefer this over the mini moog or even the ARP 2600 because it's so accessible - it really was built for musicians.
