A New Type of Synth Module

SuperKar+ is a Eurorack voice module that uses Karplus-Strong synthesis to recreate 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.

Two Instruments In One: Independent Melodies and Chords

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.

32-Voice Polyphony

Set the polyphony on the Solo Voice to maximum and SuperKar+ can play up to 16 unique voices simultaneously. If you connect it to MIDI, the Solo Voice behaves as a 16 voice velocity sensitive polyphonic sound module with stable tuning over eight octaves. Via CV the stable tuning range is six octaves.

The Chord Voice can also play up to 16 internally-generated voices simultaneously with a tuning range of five octaves. It creates harmonies based on the root note received at its pitch CV input, and can even create smart harmonies based on the root note plus a scale selection. The Chord Voice can also be used for creating compelling basslines with doubling and octave options.
