Korg Mono/Poly

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.

Here's an example of some of the bestial howls and growls made available by a Mono/Poly, with a Metal Muff pedal and a solid amp:

It has a gritty angry sound, with the Pulse Width and the effects section. Very industrial and masculine. 16 years later, it's an extension of my body! Very organic. One of my favorite tricks is to self oscillate the LPF, and then tune keyboard rate scaling for micrtonal
In a nutshell Mono/Poly is very versatile synth that will surprise me positively everytime I play it.
