Rhythm-synchronized Effects Control with Modulation Keying and Bézier Splines

This paper discusses details related to the automatic control of effects parameters. Specifically, it examines control of audio effects when synchronized with a musical piece’s rhythm. Synchronization is achieved by having control data that is periodic with the bar-length. The need for continuity in the control data is also discussed. This concept is introduced in terms of modulation techniques known as ASK and CPFSK. This is expanded upon with a discussion of a curve drawing technique that is common to computer graphics.
