How to start Aeolus on top of JACK

I always need to start Aeolus like aeolus -J. How can I make Aeolus to start automatically in JACK mode?

In your home directory, place a file named .aeolusrc (don't forget the leading dot). In this file, write all default command line arguments you'd like to use. A usual line reads like the following: -J -S /home/ce/.aeolus/stops

The option -J makes Aeolus running in JACK mode, while an -A would run it in ALSA mode.


How to pass the stops directory to Aeolus automatically

I have downloaded the stops and placed them in my home directory. Now I start Aeolus with the -S option to tell it where to find the stops, like the following: aeolus -S /home/ce/.aeolus/stops -J

Can I automate this?

Again the config file is the right place to save this persistently. In your home directory, you will find or place a file named .aeolusrc (don't forget the leading dot). In this file, write all default command line arguments you'd like to use. A usual line reads like the following:

-J -S /home/ce/.aeolus/stops

Which soundcard to use for Aeolus

Are there any recommendations about a certain soundcard?

No. You can use any soundcard supported by Linux resp. ALSA. Note that Aeolus can produce quadrophonic output. If you have four speakers, maybe you want to use a soundcard with at least four outputs.

Can I use USB-Soundcards?

I run Linux on a notebook with a cheap onboard soundcard. Can I use an USB soundcard? I heard most USB soundcards are still USB 1.1. Will this be enough?!?

Many USB soundcards run very well on Linux. Due to limitations in the USB 2 protocol, most cards are still USB 1.1. This is enough for two ins and two outs, but that's why most USB soundcards only provide two outputs, like the Edirol UA-25 or the Tascam US-122. But there are also consumer soundcards like the Terratec Aureon USB which provides 2 ins and 6 outs or the Audiotrak Maya USB with 4 ins and 4 outs. Such cards often offer 48/16 instead of 48/24 and are a bit noisy, but will do the job.


Do I need a fast machine to run Aeolus?

Processing audio sounds to eat lots of CPU power. What minimum system requirements are recommended?

Aeolus is less resource hungry. If you have a 800MHz machine, it should do the job.

What Distro is recommended?

I'm quite new to the Linux and free software world. Any recommendations about the "right" distribution?

No :) . Aeolus users run various distributions. Gentoo, Fedora, Mandrake, SusE, Ubuntu should all do the job.

For beginners, Ubuntu seems to be a good choice, but the author never has tried it, so this is a recommendation based on rumors.


Can I switch stops via MIDI?

I'd like to build a console. Can I switch stops via MIDI?

Yes, you can. See AeolusInternals20061113, a post of the Aeolus author on the mailing list. It's recommended to join the user mailing list (see Aeolus#Support_.26_participation) to get in contact with other console builders.
