• Welcome to the Pipe Organ Forum! This is a part of the open community Magle International Music Forums focused on pipe organs (also known as "church organs"), organists, organ music and related topics.

    This forum is intended to be a friendly place where technically advanced organists and beginners (or even non-organists) can feel comfortable having discussions and asking questions. We learn by reading and asking questions, and it is hoped that the beginners (or non-organists) will feel free to ask even the simplest questions, and that the more advanced organists will patiently answer these questions. On the other hand, we encourage complex, technical discussions of technique, music, organ-building, etc. The opinions and observations of a diverse group of people from around the world should prove to be interesting and stimulating to all of us.

    As pipe organ discussions can sometimes become lively, it should be pointed out that this is an open forum. Statements made here are the opinion of the poster, and not necessarily that of the forum itself, its administrator, or its moderators.

    In order to post a new topic - or reply to existing ones - you may join and become a member by clicking on Register New User. It's completely free and only requires a working email address (in order to confirm your registration - it will never be given away!). We strive to make this a friendly and informative forum for anyone interested in pipe organs and organ music.

Tutorial for Editing MyOrgan or Hauptwerk definition files


New member
Hi my friends !

As I promised to some of you, here is a tutorial to learn how an organ definition file works and to allow you to edit it.

For this job, I have taken the definition file of a free organ (Smecno Mini Set) and added a lot of comments to the most important lines. It should help you to understand how the definition file describes all the features of a virtual organ.
My tutorial may be read like a text, but it allways remains a vailable definition file.

I suggest you to download kloria MyOrgan (if you have not) http://www.kloria.com/software/musical/myorgan/ and then download the free organ Smecno mini set at : http://www.sonusparadisi.cz/organs/smecno/screenshots.0.asp . Place the tutorial in the same folder.

Try to read the original "SmecnoMin.organ" or, if you do not understand anything, read my tutorial which is the same file but with many comments.

My tutorial can be downloaded at :

Friendly :):):)

Hi Jean-Paul,

Wow, what a lot of work you have done on this. I'm certain that the others who are pursuing working with these def files will certainly appreciate you kind efforts.

more about def files

Hello my friends virtual organists :grin:

Do you need more tutorials about definition files ?
Please, let me know.



Sorry, I have given up with MyOrgan. Now I work with Hauptwerk.
I have no tutorials for Hauptwerk but I have written MYCO, a software to help making custom organs. See my site : http://organ.monespace.net/ORGANWORKS/software.html

Hi. I had a brief look at your software. It looks very interesting. I cannot commit myself to buying a license as I do not know when I would be using it if at all. At present, I am just collecting related software and organs (I have > 100 different ones between HW, GO, jOrgan perhaps some day in the future I would have something to play around with and share with others in the spirit of open source. I have enough material for 3 life-times!

Just one observation: the software screen runs off the bottom of the computer widescreen monitor and there is no scroll bar! You need to look into that.
