The monologue is a 25-key, fully programmable monophonic analog synthesizer with a voice all its own. While sharing its sleek layout, knob-per-function workflow and high-quality construction with the best-selling minilogue, monologue is a truly unique new synth for all types of musicians; featuring new voicing and sound sculpting abilities – at an amazing price.

The monologue's completely new filter, modulation, drive, and LFO can generate powerful basses and sharp leads, creating awesome mono sounds that showcase its single-voice design. The step sequencer has also been dramatically expanded, allowing more intuitive and more complex editing. With a lineup that gives you a choice of five eye-catching colors, this compact instrument has a strong personality to match your own.

Redesigned monophonic analog circuitry
The monologue contains monophonic analog synthesizer circuitry that builds on the circuitry of the minilogue. But that doesn’t mean that the monologue is simply a one-voice model of the minilogue. It’s a monophonic beast with stunning power that comes from a redesigned envelope section, modulation routing, and a filter with powerful low-end punch.

The structure is 2VCO, 1VCF, 1EG, 1VCA, and 1LFO. In addition to the same distinctive circuits as on the minilogue (such as the wave shaping that shapes the overtones of the oscillator, and a sync/ring switch), the filter section uses a two-pole filter to deliver aggressive sound. Newly featured is a drive circuit that adds overtones and distortion to the sound, letting you generate fat basses and sharp lead sounds to your heart's content. The LFO rate can be adjusted into an unprecedentedly ultra-high-speed range to generate crazy space-shattering sounds, or switched to one-shot mode to act, in a sense, as an additional envelope.

The keyboard section features the acclaimed slim keybed of the minilogue and the MS-20 mini. To make monologue a synth that any musician can immediately pick up and play, the keyboard covers the E–E range of notes - just like a guitar or bass.

Fully programmable
The monologue goes beyond analog synths in its price range by adding 100 preset locations. Select a program for instant access to great sounds - - ranging from thick basses to deep subs to brilliant cutting leads and even percussive sequences. No need to have deep synthesis knowledge; just choose a sound and tweak - a workflow that is very familiar with musicians today. Built-in programs provide 80 preset sounds and sequences made by creative artists around the world including legendary electronic artist Aphex Twin, plus 20 user locations for saving custom sounds.

16-step sequencer for highly-evolved motion sequences
The step sequencer of the monologue has been significantly enhanced to deliver musical, complex rhythms that are easy to capture, see, and edit. It supports both real-time recording with overdubbing capability as well as step recording that lets you record simply by pressing keys in the desired order, and you can also use the 16 physical buttons for quick editing or for improvisatory performance.

The motion sequence function lets you record up to four knob movements to apply time-varying change to the sound, and allows you to record not only continuously changing values as on previous models, but also values with step-wise variation. Since it's designed to let you create different sounds at each step, you can make unprecedented sequences, such as a sequence that generates a drum pattern from a single program.

There's also a key trigger function that lets you play back a sequence while you hold down a key, and even transpose it. Another new function is slide, which can be used to produce smooth bass lines by specifying portamento for each step.

Microtuning lets you freely create scales
Music has long been restrained to equal-temperament scales, and today, very few machines support microtuning. The monologue has a set of factory tunings and well as 12 user slots and is compatible with MIDI Tuning Standard 3Byte messages.

The power of microtonal music is evident in the work of Aphex Twin, who has come onboard as advisor for the implementation and also to offer scales, sounds and sequences as part of the factory presets. All players are encouraged not just to use these Aphex Twin-created scales, but also to create their own scales and explore their own world of frequencies.

Oscilloscope visualizes the sound and sequence
The OLED display will show the waveform in real time as you sculpt your sound. Visual feedback is both educational and entertaining, and represents a first on a hardware synthesizer. The monologue offers motion view that visualizes the value levels for the motion-sequenced parameters. “See” your motion sequence as it happens.

Sync with Audio Sync
In addition to 5-pin In/Out and USB MIDI, monologue includes Audio Sync connectivity, which allows it to play in time and integrate seamlessly with KORG volcas, electribes, minilogue and SQ-1. Use the monologue with your DAW as both a USB MIDI controller or a versatile analog voice. Send clock over USB and use Audio Sync to chain monologue’s clock to other Audio Sync-equipped products.

Battery-powered analog
Unlike most analog synthesizers in its class, the monologue can operate on batteries. Even if you're a hardware performer who uses numerous units, you won't need to worry about providing additional power supplies and installation space.

Awesome Synth! Making some great sounds! Can't wait to purchase a Behringer Poly!





Bought this for my husband and he loves it.I have tried it out myself and its a lot of fun.Very easy to use.



This is a very cool piece of gear!


The sounds on this guy are killer! This would be a great synth for any sort of electronic music production. Very fun to play around on and to create sounds with.




Korg Monologue is an amazing synth


Amazing synth. The 16 step sequencer and presets by Aphex Twin are unbeatable!

Great compact analog synth!


The Korg monologue is one of the most approachable and simplest synths I have ever used, but it still packs an amazing punch and has some amazing presets that are all fully adjustable. While being only a monophonic synthesizer, there is still a plethora of options for creating incredible sounds from this little synth.




Amazing Synth


This year Korg brought us the Monologue and while it is monophonic synth the options you get makes this way more than a one trick pony. Comes with 80 built-in presets that can be fully tweaked. Personal favorite part of this synth is the 16 step sequencer that can be adjusted on the fly. Great addition to the already amazing Korg line up.

Cool Sounds


You can make some awesome sounds with this synthesizer! I really love making cool sounds with this piece of equipment. Hooks right up to any amplifier and it's ready to rock. Comes with audio input, output, MIDI, and USB out. This review is from Ellis at Sam Ash in Richmond, VA.
