Description

Discover the sonic playground that is the Korg Monologue Blue, a powerful analog synthesizer that’s both accessible and inspiring. This monosynth offers a knob-per-function design, making it a breeze to dial in your perfect sound. Whether you're crafting pulsating basslines or ethereal leads, the Monologue’s analog Drive circuit adds a layer of richness and punch that brings your creations to life.

The Monologue's architecture begins with two versatile VCOs, each offering a selection of waveforms and waveshaping capabilities. The 2-pole VCF is finely tuned for monophonic bass and leads, giving your sound a distinctive edge. The built-in OLED oscilloscope provides real-time visual feedback, allowing you to see your sound as you shape it. Dive into a world of microtuning with the ability to customize scales, a feature that’s been fine-tuned with input from electronic music legend Aphex Twin.

The 25-key mini-keybed, laid out from E to E, is perfect for fitting into band arrangements, syncing seamlessly with bass guitars. Its 16-step sequencer is a powerful tool for creating dynamic sequences, complete with motion sequencing and per-step parameter locks. Plus, with 100 program memories, you can save and recall your unique sounds and sequences with ease.

Almost what I want

I love the sequencer in this thing. Sure, sixteen steps is a little limiting, but having motion sequencing is useful, and I appreciate being able to select a single step in the pattern and set parameters where I want them for that one step (well, up to four, anyway). Unfortunately, the oscillators sound a bit thin, and the built-in drive circuit is post filter for some reason, so most of the time it just ends up muddying the sound beyond recognition. I would much rather have a pre-filter drive, and I don't see why modern synth makers are creating all these budget analog synths with post-filter drive circuits. The keys feel alright, they're better than the ones found on the Microkorg or Microbrute, but the whole instrument feels rather cheaply made.

Great little synth

Great little mono-synth for the price. Exceptionally good sequencer, an ocsilloscope and 100 programmable pre-sets. Good choice if you wanna get into synths.
