• 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.

de-bounce option in Grand Orgue

Does anyone know how the de-bounce option works in Grand Orgue.
I currently cannot select it, and I would like to try it to minimize the random "thumping" I hear. Using version 1726. Thanks, Ken Barta

Debounce is only for push-buttons (like General, Divisionals). For manuals, debouncing would mean killing expression by averaging/ignoring/delaying key events.
A higher samples per buffer will result in some kind of debouncing.

More to the point, does anyone know what causes the random thumping sound in GO? I can only use version 1726, because the later ones won't recognize my USB ports, even though they're on the device list, and also won't recognize ASIO used by my EMU1212 soundcard.
Thanks, Ken Barta

With version1726 the sample rate is set at 1024 and can't be set higher. Or is there a work around for that?
Thanks, Ken

Large samples per buffer values will likely inhibt really fast playing.

Can you please explain, what the term "thumping sound" means?
Bug in a sample of the sampleset?
Clipping occurs, because it is too loud?
CPU overload, which causes some kind of cracks in sound output?
I would suggest trying to reproduce using a different sampleset (try eg. the new Kalvtrask Version from Lars) with only one register on.

To the USB problem:
If you MIDI interface is listed in the GO audio settings as MIDI device. could you please right click on an element, select "Listen for event" and send a MIDI note via the interface. Does Listen for Events recognize something?

As you suggested, I download the Kalvtrask set, and I hear similar "thumping", though not as often or as loud. I say "thumping", that is a low pitch back-beat like a small
drum would make. It really resembles an electrical EMF like a motor or other load was being turned on. The pitch is low and does not really change where ever on the keyboard you play. And it is very random, and can't be reproduced methodically. But is very annoying to hear, because it just ruins the music. When I first tried GO about 3 years ago, this "thumping" was very prominent in all the bass notes. More recent versions have improved, but it is still in the manual keyboards. The CPU is not overloaded! And there is no clipping. I hear it in all sample sets. If it is a buffer problem, then I need help to increase the buffer, or some other solution. I hear the "thumping" in notes not being played all that fast. If there keying improvements in more recent versions of GO, I can't use them. The most recent version will NOT recognize my EMU soundcard
ASIO, nor will it recognize the USB connections, even though they are listed. Right clicking on the manuals with "listen events" simply doesn't respond. As I've said before, the ONLY VERSION of recent times that I can use is 1726. It always works, but many times will not recognize my second keyboard the first time I startup the machine and load the program. I've learned to restart and reload, and it always works after that. I've set up many sample sets with this computer and version 1726, and I can usually do it without too much difficulty. In case it wasn't noted, I'm using a 4-core AMD processor at 3.2gh, with Windows 64bit 7 pro version and EMU1212 soundcard. Thanks, Ken Barta

To the "thumping": You could try switching between polyphase and linear interpolation as well as lossless compression on/off. There have been various related bugs fixed in later GO versions.

If you want to determine, if its GO sound generation or output, you can record [using a not too much stops] with the GO audio recorder. If the error is in the WAV, it is related to the sound generation.
