KORG Monologue Blue - 25-Key Monophonic Analog Synthesizer with Sequencer and Microtuning

KORG Monologue Blue - 25-Key Monophonic Analog Synthesizer with Sequencer and Microtuning

The KORG monologue Blue is a high-performance monophonic analog keyboard that takes the spirit of the minilogue and pushes it further: powerful bass, incisive leads, and organic sequences with analog drive , a 2-pole filter , and an LFO capable of reaching extreme ranges or functioning in one-shot mode as an additional envelope. With 25 slim keys (range E–E) for immediate performance, 100 programs (80 presets + 20 user), and a 16-step sequencer with real-time or step recording and Motion Sequence on up to four parameters, it's a compact and robust tool for the studio and live. It also includes microtuning developed in collaboration with Aphex Twin, an OLED with a real-time oscilloscope , and full connectivity (MIDI, USB-MIDI, Sync, Audio In) for integration with your DAW and other equipment. Its construction with an aluminum top panel, potentiometers screwed to the chassis, rubberized knobs and a wooden back, along with the possibility of running on AA batteries or a 9 V adapter, make it a portable and durable synthesizer ready for tours.

Main features

• Monophonic analog synthesis with 2 VCO, 1 VCF (12 dB/-oct, 2 pole), 1 VCA, 1 EG and 1 LFO.
• Sound with character : redesigned filter for mono, dedicated Drive circuit and VCO with sync/ring and wave shaping.
• 16-step sequencer with dedicated buttons, real-time and step recording, Motion Sequence on up to 4 parameters, step slide , key trigger , and on-the-fly transposition.
• Microtuning : 32 presets (20 presets + 6 user scales + 6 user octaves) and MIDI Tuning Standard support; presets and scales contributed by Aphex Twin.
• 25-key slim keyboard with E–E range for easy bass lines and transposition from guitar/bass.
• Advanced Display : OLED display with real-time oscilloscope and parameter movement view.
• Instant control : 23 panel controls and one assignable slider per program.
• Connectivity : Mono and headphone output (6.3 mm), Audio In (6.3 mm) for processing external sources, Sync In/Out (3.5 mm), MIDI In/Out and USB type B (MIDI).
• Memory : 100 programs (80 factory + 20 user), each with stored sequence and microtuning.
• True portability : powered by 6 AA batteries (approx. 6–8 h) or a 9 V adapter; weight 1.7 kg and dimensions 350 × 276 × 76 mm.
• Finish : Blue (Dark Blue) version within a range of five colors.

User benefits

• Bass and leads ready to mix thanks to the 2-pole filter and drive, with presence and punch without complications.
• Expressive sequences with step automation ( Motion Sequence ) and slides that provide musical movement without depending on the DAW.
• Advanced timbral exploration with editable microtuning and reference scales/artists to break out of equal temperament.
• Straightforward Workflow : Knob-per-function, on-screen oscilloscope, and 23 controls for fast, tactile sound design.
• Easy integration into hybrid setups: MIDI and USB-MIDI, Sync with Volca/Electribe/SQ-1 and Audio In for filtering/matching external sources.
• True mobility with battery power and a rugged chassis for studio, stage, or road production.

Use cases

• Electronic production : creating analog bass lines and sequences with step automation.
• Direct : Synchronize via Audio Sync with other KORGs and transpose sequences from the keyboard.
• Sound Design : Use one-shot LFO as an additional envelope for defined plucks, percussions, and transients.
• External Processing : Route drum machines or samplers through Audio In to use the Monologue's filter and drive.

Frequently Asked Questions

• Can I save my sounds and sequences? Yes, there are 100 presets (80 factory presets + 20 user presets), and each program saves its own sequence and tuning.
• Do I need a MIDI interface for my computer? No, the USB Type B port transmits class-compliant MIDI (no audio).
• Can it be powered without a plug? Yes, with 6 AA batteries (approx. 6 h alkaline / 8 h Ni-MH) or with a DC 9 V adapter (optional).
• What's the difference with minilogue? Monologue is a mono system with a 2-pole filter, dedicated drive, ultra-fast LFO, and built-in microtuning.
