Strymon SuperKar+ Synth Voice Eurorack Module

The Strymon SuperKar+ is a next-generation Eurorack synth voice designed to bring expressive Karplus-Strong synthesis into your modular setup. Built for both beginners exploring modular for the first time and seasoned synthesists looking for professional-grade acoustic textures, the SuperKar+ makes complex sound design surprisingly approachable. Thanks to its enhanced 520MHz ARM Superscalar processor and 32-bit floating point processing, this module delivers pristine, detailed tone that easily fits into any mix.

At its core, the SuperKar+ recreates the character of plucked, bowed, and resonant acoustic sounds, making it ideal for melodic, harmonic, and percussive exploration. With two independent voice channels (Solo and Chord), you can craft evolving arrangements with up to 32-note polyphony, opening the door to everything from subtle string textures to dense chordal passages. Flexible output options — Wide and Narrow Stereo, Split Voice, or Mono — ensure seamless integration into any rig, whether you’re working in the studio or performing live.

Strymon designed the SuperKar+ with a performer’s workflow in mind, offering an easy-to-read interface and per-parameter controls for attack, decay, damping, and output. Onboard MIDI expands playability, while extensive CV connectivity ensures deep modular integration. With its rugged 12HP format, intuitive layout, and high-fidelity sound engine, the SuperKar+ is a versatile synthesis tool — equally inspiring for experimental sound designers and musicians looking to add lifelike acoustic energy to their modular system.
