Revisited Algorithm

Pluck is based on the “Digitar” algorithm by Kevin Karplus & Alexander Strong, an absolute classic in digital audio synthesis. Using a tuned delay with feedback, an impulse generator actuates it, causing an oscillation that sounds reminiscent of a guitar string. This method has since been refined and used in a myriad of different electronic instruments, yet the simple original is still full of charm and beautiful tones. While staying true to the simplicity of the original structure, Pluck also introduces modern digital filters and a variable impulse generator for a wider range of timbres and tones. It’s a six-stringed homage to a beloved algorithm and sound.
