KORGphase8 8-Voice Acoustic Synthesizer

Independent shopping perspective
The Korena take
KORG phase8 creates sound with eight independently controlled, electromechanical steel resonators rather than a conventional oscillator bank. Choose eight of the 13 chromatically tuned resonators, fine-tune or swap them, and shape each voice with velocity and ADSR envelope controls. The resonators invite direct interaction by touch, plucking, strumming, tapping, or objects; the AIR slider changes their acoustic response and interaction level. Its polymetric sequencer records steps or unquantized performances, automates panel controls, and connects to wider setups through MIDI, USB-MIDI, CV, and sync.
Strong match
Who this is for
- Building evolving eight-voice patterns with polymetric sequencing, automation, and per-resonator envelope control.
- Exploring alternate tunings or custom scale layouts by selecting and tuning eight of thirteen resonators.
- Integrating a physical acoustic-synthesis instrument with MIDI, USB-MIDI, CV, and sync-equipped gear.
Consider the trade-offs
When to look elsewhere
- Setups that require all 13 included resonators to be installed simultaneously; phase8 installs eight at a time.
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Per-resonator ADSR and velocity
Attack, decay, sustain, release, and velocity intensity are controlled for each resonator.
Detail 03
Eight program slots
The sequencer stores eight programs.
Detail 04
AIR slider
It controls acoustic response and the level of physical interaction.
Detail 05
CV input
The CV input accepts plus or minus 5V.
Final check
Know before you order
- 01The instrument uses a DC 12V AC adapter; an AC adapter is included.
- 02Only eight of the included 13 resonators are installed at one time.
- 03Its MIDI ports use the TRS-A format, alongside USB-C USB-MIDI.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How many voices does phase8 have?
It has eight independent electromechanical voices.
02Can I change the resonators?
Yes. The steel resonators are swappable and tunable. Thirteen chromatically tuned resonators are included, with eight installed.
03Can the sequencer control external MIDI equipment?
Yes. External MIDI notes can trigger phase8, and its sequencer can send MIDI output.
04What outputs are available?
It provides a 1/4-inch line output and a 3.5mm headphone output.
