Digitally enhanced diatonic instrument

Abstract

A digitally enhanced diatonic accordion is disclosed, integrating electronic input systems, audio signal processing, and bellows simulation to replicate and expand the expressive capabilities of a traditional accordion. The system includes a matrix of tactile push buttons for note entry, a joystick-based interface for emulating bellows dynamics, and programmable multi-tonal switching between sampled and synthesized sound sources. A digital audio processing pipeline blends input parameters such as note velocity, button state, and bellows motion to produce dynamic audio output through multiple oscillators and wavetables. Onboard signal effects such as reverb and chorus are applied prior to final mixdown. All components are mounted on a compact microcontroller-based printed circuit board featuring multiplexers, capacitors, audio interfaces, and potentiometers for real-time control of tonal blend and volume. The system offers an ergonomic and modular platform for performing, recording, and teaching, while enhancing traditional accordion functionality with digital flexibility and expressive nuance.
