"Strum is Karplus-Strong synth, written completely
in assembly. Very simple and clean UI with visual
feedback of used/unused features for easy overview.
Two different and independent string generators for
more variety of sounds, with own feedback, string
length, attack/decay envelope and vibrato settings.
First OSC is trying to simulate basic
characteristics of four basic string types - nylon,
bronze, steel and flatwound. Second generator uses
basic shapes - sine, saw, triangle and square with
additional options to tweak (tension & position)."
