Aeolus - www.muse-sequencer.org

Aeolus is a pipe organ emulator written by Fons Adriaensen. It was released as free software (GPL license). This page mainly tries to be a central place to concentrate resources related to Aeolus. It is a wiki, but for spamming reasons you need an account to log in. Ask for an account on the mailing list if you want to contribute.

Features

Running on top of a GNU Linux system (x86 and AMD64)
Sound output either via ALSA directly or via the low latency soundserver JACK (strongly recommended)
Very realistic synthesized sound, not based on samples
Exchangable instrument. The current stop set mainly mirrors a german baroque instrument, but it could be switched to any other instrument
Easy to use user interface

Intention

A short explanation by Fons Adriaensen, the author of Aeolus, as found on his homepage:

Screenshots

That is how Aeolus looks like. Switching stops using a notebook with touch screen must be a joy :) :

Operation

Using Aeolus is simple if you have basic knowledge about professional linux audio. But even as a beginner you should be able to get your system up and running Aeolus.

The preferred audio driver system to use is ALSA, not the (deprecated) OSS. You can run Aeolus on top of ALSA directly, or (highly recommended) run the realtime soundserver JACK on top of ALSA and tell Aeolus to use JACK.

For the basic system setup read the very good instructions by Musikun.

About Aeolus setup and usage, there is some non-exhaustive information on AeolusUsage. Maybe even AeolusFaq is useful for you.

John Dey has built a cool console:

Installation

Currently there are no ready to use binaries yet. It will last some time until the distributors will provide packages. If you are familiar with building from source, get it from the Aeolus homepage. See Musikuns excellent page for help with compiling.

Note that the latest version also compiles on a AMD64 (Gentoo) and using the instructions you might be able to get it running. If you get no audio sound using Jack, try as root. If that works some work has to be done :) considering the soundserver.

Contributing

Even as a normal user with limited computer knowledge, you can help with the development of Aeolus. What Aeolus needs so far:

Creating or improving existing Aeolus stops. This can be done by any organist with some acoustical knowledge
Recording stops of true instruments. If you have access to a good instrument, you are invited to do such a recording which can be used to create new stops from it. Top wish: A french romantic instrument.
Doing audio measurements of rooms with Aliki. If you have access to a church or concert hall with interesting audio characteristics, an acoustical fingerprint would be cool.

Please contact the mailing list or Fons Adriaensen directly if you can help the Aeolus project.
