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

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

The KORG monologue Silver is a monophonic analog keyboard designed for powerful basses, defined leads, and sequencing with realistic movement. It shares the philosophy of the minilogue, but with its own architecture (2 VCO/1 VCF/1 E G/1 VCA/1 LFO), a 2-pole filter optimized for mono, and a Drive circuit for harmonics and character. Its 25-key slim keyboard with velocity sensitivity (range E–E) promotes agile bass lines and melodies, while the OLED display with oscilloscope shows the waveform and parameter changes in real time. It includes 100 programs (80 factory + 20 user) and a 16-step sequencer with 16 physical buttons, real-time or step recording, and Motion Sequence for up to four parameters. Microtuning , developed in consultation with Aphex Twin, allows you to create and load alternate scales. With MIDI, USB-MIDI, Sync and Audio In connectivity, plus battery operation, the Monologue Silver is a robust and portable solution for studio and performance.

Main features

• Monophonic analog synthesis : 2 VCO, 1 VCF (12 dB/-oct, 2 pole), 1 VCA, 1 EG, 1 LFO.
• Sound with character : specific filter for mono and dedicated Drive for fuller bass and aggressive leads.
• 16-step sequencer with 16 buttons, real-time and step recording, Motion Sequence (up to 4 parameters), step slide , key trigger and transpose.
• Advanced Microtuning : 32 settings (20 preset scales, 6 user scales, 6 user octaves) and MIDI Tuning Standard support.
• OLED display with oscilloscope that displays the waveform and parameter movement in real time.
• 25-key slim E–E keyboard with velocity sensitivity, designed for fast, musical playing.
• Full connectivity : mono output, headphones, Audio In for processing external sources, Sync In/Out, MIDI In/Out and USB Type B (MIDI).
• Portability : Operates on 6 AA batteries or a 9V adapter; aluminum top panel and wood back construction.
• Finish : Silver version within a range of five colors.

Product benefits

• Bass and leads ready to mix thanks to the 2-pole filter and Drive that provide presence and analog punch.
• Expressive sequences using step, slide , and transpose automation, without relying on a DAW.
• True timbral exploration with editable microtuning and reference scales/artists to go beyond equal temperament.
• Instant workflow : Dedicated knob-per-function controls and oscilloscope accelerate sound design.
• Easy integration with hybrid MIDI/USB-MIDI setups and direct synchronization with other KORG equipment via Audio Sync.
• Studio and stage mobility with battery power and rugged chassis.

Use cases

• Electronic Production : Analog Bass Lines and Patterns with Motion Sequence .
• Live : Audio Sync synchronization and on-the-fly transposition of sequences.
• External Processing – Filter or colorize drum machines and samplers via Audio In .

Frequently Asked Questions

• How many programs does it include? 100 locations (80 factory presets and 20 user presets). Each program saves its sequence and microtuning.
• Is the keyboard velocity-sensitive? Yes, it's a slim, 25-key velocity-responsive keyboard.
• Does it work without a plug? Yes, with 6 AA batteries (approx. 6 h with alkaline / 8 h with Ni-MH) or with a DC 9 V adapter (optional).
• Are batteries included? 6 AA batteries are included for operational verification.
