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.

To get that fat, creamy sound on a Mono/Poly, you need to set the oscillator levels right. VCO1 Triangle, volume 100%, then all the other VCO's at about 20% volume on whatever waveform you'd like (maybe PWM or 3 detuned triangles).

This gives you a far warmer sound and is great for Basses. This setup sounds pretty moog-like to be honest when you combine it with the 24db filter.

A raw sound, a peculiar beast. Used as a 4 VCO mono, it doesn't mananage the fat, creamy sound you would expect, at all. To my ears it always sounds raw and unpolished, not particularly nice for bass, nor for leads. It's sweet for Tangerine Dream-ian sequence runs with the arpeggiator, some metalic plinks and plonks here and there, and maybe the obvious fun of playing it 4-voice poly with some wonky detuning. It looks very nice, and it's a synthesist's synth for sure, but it just never floated my boat.

Wow, 20$, that's amazing! I picked mine up in the fall for 700$ and thought I got a great deal. Now one of my favorite synths, such an inspiring design.

Will you believe it ? A friend of mine, living in Paris, gave me a M/P a month ago ! I'm in a dream. Please never wake me up. The best keyboard i ever had.

I had one of these in the 80s. Bought it brand new on HP when I was 17 (my Dad had to sign the forms) sooooooooooo regret getting rid of it a few years later when getting money for going on the piss was more important. Someone recently said to me "Never sell gear - you'll regret it one day" -- too true. Remember having a lot of fun with it.
