We built a physical version of the Karplus-Strong physical model for strings. There is a whole group of Karplus-Strong algos and we are using a bunch of them. We built 3*3 sound engines that are each producing four voices.

kHarper is easily epic and cinematic. Can do big bwaaps as well as slow and emotional chords. Unlike a banana.

4 strings
Every string is a voice. The strings are built out of two touch strips with an LED bar in the middle, showing you what kHarper is doing. Each string has a knob on top to set the tone and a CV -in below. You can also patch in a gate to pluck the string.

kHarper has a very wide range of sounds. You can go from wild distorted guitars to meditative soothing plinkies. Just like any other stringed instrument there are 10.000 ways to play.

Being able to touch these Karplus-Strong models adds the natural chaos of a physical manifestation. Plucking amazing.
