Development of electronic instrument using rotary encoder

Sound frequency control by rotation velocity of rotary encoder

Abstract

Electronic instruments can generate special sounds by synthesizing pre-memorized sound elements, which have capability to cause larger fever than ordinary instruments. To play these electronic instruments with complete control, we need much training to learn complicated key and lever operations.This causes difficulty for beginners to approach these electronic instruments. In this study, we proposed a novel electronic instrument using a rotary encoder and a PIC micro computer. We then described the abstract of the proposed instrument and design concept based on preliminary survey about usability of instruments.
