Independent shopping perspective
The Korena take
SYNTRX II places a fully analog sound engine behind a 16 × 16 digitally controlled analog patch matrix, replacing patch cables with stored routing. Two audio-rate oscillators, a third oscillator that reaches audio range, ring modulation, sample and hold, and a looping trapezoid envelope provide the raw material for detailed experimentation. Recordable joystick movement, 256 patch memories, and the integrated 16-step piano-roll sequencer make it practical to capture and revisit evolving setups without rebuilding the routing each time.
Strong match
Who this is for
- Recalling complex cable-free analog routings during a live improvisation set.
- Recording joystick motion and layering it with sequenced patch-matrix control.
- Processing external line, microphone, or DC-coupled signals with internal modulation.
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
Recordable joystick
Its two bipolar CV axes can be recorded, overdubbed, and replayed.
Detail 03
Piano-roll sequencer
The matrix supports sequences of up to 16 steps, with selectable directions and gate lengths.
Detail 04
External inputs
One line input includes an envelope follower; the second accepts DC-coupled line or microphone input with gain switching.
Detail 05
Filter self-oscillation
At high resonance, the multimode filter can produce a sine wave.
Final check
Know before you order
- 01Use the supplied 12V DC center-positive power supply.
- 02The main audio outputs are two line-level connections.
- 03The model is specified with a USA plug.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How are patches routed on SYNTRX II?
Routing is handled by a 16 × 16 digitally controlled analog patch matrix, rather than conventional patch cables.
02How many patches can it store?
It has memory for up to 256 patches.
03Can it receive MIDI?
Yes. It has DIN5 MIDI In, MIDI Thru, USB MIDI, and MIDI control for note, velocity, pitch bend, mod wheel, and CC.
