Aeolus

Aeolus is a pipe organ emulator using additive synthesis as a VST, AU, or CLAP plugin (or a stand-alone executable).

Aeolus was originally developed by Fons Adriaensen and presented in 2004. The original implementation is Linux only and can be found here (or across Linux distribution packages). At present it looks like Aeolus development has been mostly abandoned (but Organnery picked up the original Aeolus project to make it run on a Raspberry Pi).

This project leverages the wavetable synthesis part of the original Aeolus, improves on it, and delivers it as a virtual instrument plugin using JUCE framework, so that it can be run in Windows/macOS/Linux VST3/AU/CLAP hosts.

This implementation contains additional improvements to the sound generation including:

• Pipes chiff noise on attack;
• New pipe models;
• Convolutional reverb.

The original binary format for the pipe models and the organ configuration has been translated (partially) to JSON.
