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.
Deceptively Powerful, Invitingly Simple And Intuitive.With an interface that can be understood at a glance, the sheer amount of music you can create with a single SuperKar+ module borders on mind-blowing. It draws you in, allowing you to generate full-sounding arrangements with as much musical and timbral variation as you can imagine via CV connections. Powerful enough to be the center of endless sonic exploration, SuperKar+ delivers all of this in a compact 12HP form factor.
Self-Contained Voice Module
The nature of Karplus-Strong synthesis means that you won’t need to dedicate VCAs or amplifier envelopes to SuperKar+. Independent attack, decay and damping are included for both the Solo and Chord voices, and the module also includes an internal mixer with independent output levels for both voices, as well as multiple stereo and mono audio output modes.
SuperKar+ Values Your Input
The Solo Voice and the Chord Voice each have their own audio inputs, which can be used to not only excite the string or tube, but to transform either channel of SuperKar+ into a sympathetic resonator array for advanced or creative scenarios.
But what exactly is Karplus-Strong synthesis? In this scenario, a very short delay line with high feedback is excited by a sharp transient or burst of noise to produce a pitched sound, which is very similar to the principle of plucking a string. Longer excitations can create bowed string sounds, and when the polarity of the feedback structure is reversed a pipe or tube-like timbre can be produced instead. In SuperKar+ this method of synthesis almost seems to be alive, responding dramatically to slight changes in attack and decay times.
