K-Byte is the unofficial name of the sound driver used in Commodore 64 games, several of which are known to be developed by K-Byte.

Right from the beginning, arrangers could freely modify all registers of the SID chip. In 1985, vibrato and pulse width modulation (PWM) with hard-coded settings were added. In 1988, independent PWM speed for each voice, pitch bends and filter modulation were added.
