Korg Phase8

The Korg phase8 Acoustic Synthesizer is designed for sound designers, producers, and performers who want hands-on physical interaction with synthesis. At its core are eight independently tunable metal resonators that physically generate sound.

Using Korg's Acoustic Synthesis technology, phase8 generates sound through physically vibrating steel resonators, paired with precise electronic control. Eight independent electromechanical voices form the core of the instrument, giving each note a natural response that reacts to touch, movement, and acoustic feedback. This approach creates tones that feel active and responsive, rather than static or purely electronic.

Eight-voice acoustic synthesizer using KORG's Acoustic Synthesis technology for physically generated sound

Electromechanical voices with swappable, tunable steel resonators deliver tactile, organic tone

13 included resonators allow for chromatic tuning and customizable setups with 8 installed at once

Haptic sound generation reacts to touch, plucking, tapping, and acoustic feedback for immersive play

Polymetric rhythm sequencer supports step-based and unquantized live recording with per-voice step skip

Three amplitude modulation modes including tremolo and two pitch-sensitive audio-rate modulations

Optional harmonic quantization for modulation effects adds tonal control

Trigger delay control for offsetting sound timing via tempo-synced shift knob

Parameter automation records all knob movements into sequences for evolving sound design

Real-time interaction lets users shape tones physically and creatively with external objects

AIR slider adjusts the acoustic sensitivity and response of physical interactions

MIDI, USB-MIDI, and CV input provide full external control of parameters and note triggering

Sync In/Out and MIDI sync allow tempo alignment with external gear

Sequencer can also send MIDI notes to external instruments for hybrid setups

Compact design with ¼" audio out, 3.5mm headphone out, and USB-C for firmware updates

Includes power adapter, hex key, quick start guide, safety sheet, and five extra resonators
