Soul from Scratch - Designing a More Portable Organ

Explore the process of digitally recreating the iconic Hammond B-3 organ in this conference talk from Strange Loop. Learn about the technical design of the Hammond B-3 and the Leslie rotating speaker cabinet, and discover how to model their audio components digitally for implementation on a microcontroller. Gain insights into creating a lightweight, portable organ synthesizer with full MIDI control of notes, drawbar settings, and effects. Follow the speaker's journey through successes and failures in the initial design, and understand the optimizations that enable the simulation to run on a low-powered device. Suitable for creative programmers, music enthusiasts, makers, and optimizers, this talk provides the foundational knowledge needed to create your own synthesizer. Topics covered include oscillators, direct digital synthesis, phase increment, volume, vibrato, percussion, and amplifier simulation.
