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.

After the successful rebirth of the MS-20, this one or the Polysix could be prime candidates to receive a re-release. Great, powerful synthesizers that can deliver truly robust sound.

If Korg releases a modern MonoPoly, I'd buy it immediately.

I think some commenters are commenting on the sound of the Software version of Mono/Poly which was made back in 2007. The sound is not comparable. Not even close. The software sounds thin and weedy with none of the same character as the original.

Don't get me wrong, I love software and it's come a long way since 2007 but the sound of a real mono/poly is so different.

The filter is unique. Before it self-oscillates, the resonance somehow sounds separate from the meat of the signal. It's pretty strange and maybe not preferable to some people. Add a little bit of saturation or something else to sort of combine the signal and it sounds great.

It's tempting to stack all 4 oscillators, but it still sounds so good using only 1 or 2. It does bass very well, and I don't understand people who say otherwise. Are they're talking about the software version? Try a saw and triangle an oct lower. Need more fat? Add another saw. This thing sounds killer.

This is a very strange synth with tons of modulation capabilities. The knobs are everywhere and the arpeggio is quite different, as all voices can be modulated. Even with all the capabilities, I never really enjoyed playing this synth. I would spend tons of time on it, but somehow it didn't sound nearly as good as my Korg Poly6. The sounds were thin and tinny sounding; it just wasn't for me.

Would you believe some random stranger paid me £3000 to take their Mono/Poly?

No, I wouldn't either. I hate the ridiculous fantasies that people write in the comments section.
