Erica Synths SYNTRX II – Analogue Desktop Synth Inspired by Synthi AKS

The SYNTRX II channels the spirit of the EMS Synthi AKS into a modern instrument. It merges three analogue oscillators, a recordable joystick, a digitally controlled analog patch matrix, built-in FX, and a piano-roll sequencer—all wrapped in an expressive, performance-ready desktop design. It’s experimental sound design and tactile control in one interface, crafted for adventurous creators.

Key Features

• Three analogue VCOs: Two main oscillators with CV-controlled waveshaping and sync, plus a modulation oscillator that doubles as LFO or sound source
• Stylized filters: Series-connected high-pass and low-pass filters with resonance for sculpting voices and textures
• Live-shaping tools: Ring modulator, multi-colour noise, looping trapezoid envelope generator with VCA, and two output VCAs
• Joystick controller: Recordable X/Y joystick with attenuator and manual gate for dynamic modulation
• Analog patch matrix: 16×16 digitally controlled crosspoint matrix with three attenuation levels per connection, storing up to 254 patches
• FX section: Built-in delay and reverb powered by DSP, giving spacious ambience without external gear
• Piano-roll sequencer: Integrated step sequencer with two stepper modulation sources for rhythmic and melodic programming
• Inputs & I/O: Two DC-coupled instrument inputs with inversion and envelope followers, audio/CV scope output, CV inputs, Gate In, MIDI In/Thru, assignable outputs, headphone output, and VU meter
