SuperKar+ is a Eurorack voice module that uses Karplus-Strong synthesis to create the sound of plucked or bowed strings, struck or blown pipes or tubes, or a suite of other sounds from percussive textures to legato melodies and chords with smart harmonies. This is Karplus-Strong synthesis at its most intuitive and captivating.

Karplus-Strong is a form of delay feedback synthesis, where every tone and texture is constantly in a state of varying tension. SuperKar+ is an engagingly responsive instrument, as tiny changes in attack/decay time and damping create an infinite variety of subtle or dramatic timbral shifts, and variable random per-note detuning can create lifelike realism.

SuperKar+ is divided into two halves or voices: a Solo Voice and a Chord Voice, both of which can be played simultaneously and independently of each other if desired. Both voices can be triggered and pitched independently via control voltage, while the Solo Voice can also be controlled polyphonically via MIDI.

Independent timbre selections are available for both voices, and each voice has its own independent level control and can be routed through a separate audio output if desired.
