Looking at the software listed at Kokkini Zita it's easy to see where developer Fons Adriaensen's interests lie. He has written one of the best organ synthesizers for Linux, he has contributed to the LADSPA collection of processing plugins, and he has provided Linux sound researchers with some excellent tools for measuring and representing audio signals. He is also involved in improving Linux support for the Ambisonics technology of encoding and decoding multichannel audio.

Fons is a rather prolific developer, so I'll limit my reviews here to only the applications I've employed here at Studio Dave. Alas, I haven't yet got into using his Ambisonics utilities, but perhaps one of my readers will add a comment on that software.

Aeolus

In ancient Greek mythology Aeolus was the god of the winds. Aeolus is thus a perfect name for Fons's flagship organ synthesizer. Indeed, to many listeners Aeolus is the best-sounding organ synthesizer available for any platform. A bold statement, to be sure, but in this writer's opinion Aeolus definitely lives up to and even surpasses its hype.

Aeolus is a bona fide synthesized organ, i.e. it does not use sampled audio for its sound-creation engine. Aeolus works with combinations of stops and manuals in a manner similar to a real organ to control the the frequencies and amplitudes of the pipes. One of Fons's main intentions was to design a virtual organ that an organist would feel comfortable playing, and anyone who has used a real church organ will likely feel right at home with Aeolus and its sound.

The following list from the Aeolus Web page summarizes the organ's main features :
