• 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.

We strive to make this a friendly and informative forum for anyone interested in pipe organs and organ music.

GO swellbox modelling

I haven't (yet) come across any mention of this as I've searched back through the archive. Please forgive me if I'm covering old ground again.

We're all aware, I think, that the perceived tonal quality of the ranks in a swell box changes as the shutters are opened or closed. In other words, the sound is (obviously) attenuated but also 'muffled' when the box is shut and, as the shutters are opened, the volume increases and the sound becomes increasingly unveiled.

I don't think that I detect that effect when I open and close the swell box in GO. So the point of this thread is to ask if such a feature could be incorporated into GO to improve the realism of enclosed divisions in the organ?

If it's of any interest, I know that Colin Pykett did a lot of work on this aspect of swell box imitation some years ago. I think in those days he was achieving the effect in the analogue domain by means of voltage-controlled low-pass filters.

Here's a link to some of his work:

I know that the analogue circuitry is no longer relevant, but perhaps his findings on the required characteristics of the filtering may be.

Thanks for any input on this idea!

Cheers,
Gerald.

Thanks for the pointer.

The current GO swell is simply volume based.

Regarding your request:

As you might have noticed in this forum, the current GO topic is reverb, which is far from finished. Its totally open, what will be picked up after.
You could file a feature request at the sf.net project, so that it is not forgotten.

Yes - I've certainly noticed the activity on Reverb and have been following it avidly. It begins to look very promising.

I think I've just succeeded in filing a feature request for swellbox modelling at SF (there's a first time for everything) so I hope that someone will one day think my request worthy of incorporating.

I'm greatly enjoying my newly-embarked-upon journey of discovery with GO. It is looking like it's so much better than what I've been persevering with for the last 7 years or so. I'd like to add my grateful thanks to everyone who has contributed to producing and improving GO. THANK-YOU, ALL!

Cheers,
Gerald.
