My first prototypes were done with Aeolus, which is a simple but limited additive synth with up to 64 components. This distro utilizes GrandOrgue, a very specialized Pipe Organ emulator and sampler, running headless on a framebuffer and loading a number of postprocessing plugins if necessary. It Is capable of not only sounding hyper realistic but also running very complex register combinations via midi, with 24/96 multi-attack multi-release samples. Raspi4 Is the first generation able to run the hundreds of simultaneous streams needed for this task.
