Dear Zynthian,

as a classical church organist, I’m interested in a pipe organ engine. The Zynthian website promotes Aeolus, but it’s neither installed on my standard Zynthian, nor can I select it in the WebUI. Also a manual installation by ssh as explained in [Link](https://discourse.zynthian.org/t/new-engine-implementation-aeolus-pipe-organ-emulator/2060?page=2) does not work, since I receive the message “Unable to locate package Aeolus”…

So is Aeolus phased out? If not, how can I install it then? If yes, which other (free) pipe organ engines can you recommend?

Thank you for your answers and have a good start in 2024!

Hi @DocMC!

The current version of Zynthian has an odd limiation for Aeolus in that it must occupy the first 4 chains (MIDI channels). As soon as you add a chain that uses any of channels 1-4, Aeolus is hidden from the menu. Remove those chains and you should see it in the list. We will be fixing this in a future version.

😆 That’s really a very strange bug… And in fact, deleting all my standard instruments, I can select it… and it seems to work :-D.

Thank you so much, now I think I have everything I need for my live performances (bigband on the on side, worship on the other).

Best regards,

To be fair to @jofemodo, this isn’t a bug but a pragmatic way to implement the standard Aeolus engine that has this limitation but as I say, we have plans…

OK, thank you for this comment. And @jofemodo , I absolutely appreciate your work on Aeolus. Just have been checking it for 15 min., but I’m already impressed by Aeolus: Good sound, good control (adding 16", 8", 4",…). Seems like an organist has coded something great and adapted it to a tiny box in the best way possible!

Aeolus has its roots here  
[https://kokkinizita.linuxaudio.org/linuxaudio/aeolus/](https://kokkinizita.linuxaudio.org/linuxaudio/aeolus/)  
And there is also the first lecture, which explains how the synthesis is carried out.

Two days ago I was looking for Aeolus, and I couldn’t figure out where he hid, now I know that with busy channels I won’t find him 🙂

Sorry for my mistake, I fixed the links and they should work.

> Hi gang! I am working on some enhancements to Aeolus integration with Zynthian which should drop in the next stable release. Aeolus is a pretty good pipe organ simulator. It uses generative algorithms to emulate the various sounds of pipe organs, not samples and is very configurable. Zynthian uses the default Aeolus configuration which presents a Grand manual, two Swell manuals and a pedal board. (Excuse me if I get things wrong. I am not a pipe organ specialist.)
