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.

Erica Synths SYNTRX II Analog Synthesizer - USA Plug construction detail

Detail 01

16 × 16 patch matrix with three attenuation levels per point

Signals can be routed with three available depth settings at each matrix point.

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

  1. 01Use the supplied 12V DC center-positive power supply.
  2. 02The main audio outputs are two line-level connections.
  3. 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.
