Analogue module loosely based on Karplus-Strong synthesis
This module is loosely based on the Karplus-Strong algorithm. You may get it to make some plucked string sounds or you might just get lost in a rubbery glitch mess. Most likely, Messrs. Karplus and Strong would drag me out into the carpark for a kicking if they heard this module...or even saw the name.
