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

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

The KORG monologue Black is a monophonic analog keyboard designed for punchy basses, incisive leads, and evolving sequences. Based on the minilogue philosophy but with its own architecture (2VCO/1VCF/1EG/1VCA/1LFO) , it incorporates a 2-pole filter optimized for a single channel, a Drive circuit that adds harmonics, and an LFO capable of working at extreme speeds or in one-shot mode as an additional envelope. Its 25-key slim keyboard with velocity sensitivity (range E–E) offers agile performance, while the OLED display with oscilloscope shows the waveform and parameter movement in real time. With 100 programs (80 presets + 20 user) and a 16-step sequencer with Motion Sequence for up to four parameters, the monologue Black combines portability, sonic power, and full integration via MIDI, USB-MIDI, and Audio Sync . It also includes microtuning with scales and tunings created in collaboration with Aphex Twin to explore territories beyond equal temperament.

Main features

• Monophonic analog engine with 2 VCOs, 12 dB/−oct (2-pole) VCF, VCA, EG and LFO.
• Sound with character : Redesigned filter for mono and dedicated Drive for fuller bass and aggressive leads.
• 16-step sequencer with real-time/step recording, 16 physical buttons, key trigger , transpose and Motion Sequence on up to 4 parameters.
• Advanced Microtuning : 32 settings (20 preset scales, 6 user scales, 6 user octaves) and MIDI Tuning Standard support.
• OLED display with oscilloscope to view waveforms, values, and automations.
• 25-key slim (E–E) keyboard with velocity sensitivity for greater expressiveness.
• Full connectivity : mono and headphone output (6.3 mm), Audio In , Sync In/Out (3.5 mm), MIDI In/Out and USB Type B (MIDI).
• True portability : powered by 6 AA batteries (approx. 6 h alkaline / 8 h Ni-MH) or 9 V DC adapter; weight 1.7 kg; dimensions 350 × 276 × 76 mm.
• Finish : Black version within a range of five colors (Silver, Black, Red, Dark Blue, Gold).

Product benefits

• Bass and leads ready to mix thanks to the 2-pole filter and Drive that provide punch, presence and analog character.
• Expressive sequences with step automation and slide and transpose functions that generate dynamic patterns without relying on a DAW.
• Timbral exploration through microtuning inspired by Aphex Twin and editing scales/keys outside of equal temperament.
• Instant workflow : knob-per-function interface with 23 controls and program- assignable slider .
• Easy integration with hybrid setups: synchronize via Audio Sync with volca/electribe/SQ-1 and control via MIDI or USB-MIDI.
• Mobility and durability : aluminum chassis with anchored potentiometers, rubberized knobs, and a wooden back.

Use cases

• Electronic Production : Creating analog basslines and complex sequences with Motion Sequence .
• Live : Audio Sync synchronization and on-the-fly transposition to perform patterns with on-stage variations.
• Sound Design : Using the LFO in one-shot mode as an additional envelope for plucks and defined percussive sounds.
• External Processing – Filter or colorize drum machines and samplers via Audio In .

Frequently Asked Questions

• How many programs does it have? 100 locations (80 factory presets and 20 user presets), each of which can store its own sequence and microtuning.
• Does it record automation? Yes, up to 4 Motion Sequence tracks per program.
• Can I use it without an external power supply? Yes, with 6 AA batteries (approx. 6 h alkaline / 8 h Ni-MH) or with a DC 9 V adapter (optional).
• Does it include sound management tools? It's compatible with Monologue Sound Librarian for organizing and loading sound banks.
