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.
