• 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.

Tutorials for looping and releases of samplesets?

I am very interested in making own samplesets for GrandOrgue.
There are some articles about this. Also some tools like LoopAuditioneer and TWE.
Unfortunately, I couldn't find (easy) tutorials about looping and releases.

So far, I managed to record some sample files. But I don't understand how to set loops and releases. (Sound keeps playing after release of key).

Dou you have some links or tips?

Thanks in advance, Marco

Hi!

It's easy, open a (noise reduced and cut) sample in LoopAuditioneer and click the magnifying glass in the toolbar (or click Ctrl + Z on the keyboard) to search for loops. If you want some hints to how to adjust the settings read the user guide at http://loopauditioneer.sourceforge.net/userguide.html. Be sure to listen carefully to the loops you wish to keep before saving as not every one will be good!

To set a release marker right-click on the waveform where you want the release and click Add cue in the pop-up menu. When you're happy with the loops and release you just save the sample.

Also be sure to read my pages on sampleset creation at http://www.familjenpalo.se/vpo/sampleset-creation even if I don't have written about loops and releases there yet.

Kind regards

Hi,

Thank you for the tips.
I did read your pages.
Now I followed the tips. I did noise reduction, added a loop and a cue point.
The problem is: when I open my test organ in GrandOrgue, the changes to the wav-File have no effect.
My impression is, that some old files are loaded. I cleared the cache and reloaded, but still the same. The paths in the ODF-File seem to be correct.
Do I miss something? I would love, if there would be a "How to create virtual organ sample sets for Dummies"-article ;-)


Nonetheless: GrandOrgue is a very good virtual organ software!!!!

GO does not look for changes in the wav files, so clearing the cache + reload is required in such sitatution. You can temporary also disable the automatic cache managment in the GO settings, so that you don't have to delete a automatically generate cache over and over again.

GO allows allows you to specifiy/override the loops/cue points via ODF, so you could put these values into ODF. That way, you can verify, if they sounds the same.

Problem with finding loops

Hi, I finally succeded in creating wav-files with correct loops and cue points.

But I have problems finding loops, which don't have noise at the end/beginning of the loops.

What are the tips and tricks to get rid of the noises or to find loops without noise? Do I need longer samples?

I would be glad, if there would be a couple of tips.
There is a nice 4 manual organ with french disposition waiting for me ;)

Thanks in advance, Marco

Hi!

One of the most common problems when trying to find loops is modulation of tone and even more importantly changes in the background noise over time during the sustainsection. Longer samples are usually easier to loop. Nowadays I'd record around 10 seconds of stable tone for main samples. With at least 4 seconds stable tone you'll get something usable especially in the higher range but more is better... Compund stops also usually need longer sustainsections. Always remember to give enough time in between the samples too so that the reverbtail is completely clean.

But mostly I'd suggest that you should be very particular about the noise reduction of the samples as problems at that stage certainly could result in samples that are difficult to loop.

This is of course only general advice. To be able to give you more particular advice I'd need more information to work with. I'd like to have access to the raw recording of a sample as well as your noise reduced version. I'd also like to know more of your methods and workflow to be able to provide better help.

Kind regards

Thank You. Seems that my samples are way to short. Let me try with shorter samples before sending you some files. I keep you posted.

It certainly is possible to loop shorter samples but it will be much more difficult to have the loops sound natural. Then again, longer samples will also make the sampleset larger and require more memory. I can only say that over time I've begun to record longer and longer sustainsections. My first recording of Bureå funeral have sustainsections around 1.5 to 2 sec. Bureå choir on the other hand have around 6 to 8 sec sustainsection length and in future recordings I'll try for up to 10 sec in the more important stops or parts of stops.

Kind regards
