1. I am getting sound, but there is static and crackles. What can I do?


You need to adjust the audio buffer numbers and/or size. The simplest way to do this is to use the Customizer (click on File, then on Customize). Click on “Next” a few times until you get to the last page, called “Customize Fluidsynth Sound”. You need to increase the number of samples in the buffer (typically 8 – modify it by increasing it by even numbers of samples i.e. to 10 or 12 etc.) and /or the buffer size (typically 512 – modify it by factors of two i.e. to 1024 or 2048 etc.). These increases will worsen the latency (i.e. increase the delay between playing a note and hearing the sound), so you should not overdo this. Press “Enter” before clicking on “Finish”. And if you are satisfied with the changes, make sure that you save the disposition.


2. I don't like the delay between playing the note and hearing the sound. What can I do?


Consult the answer given above, but reduce the buffer numbers and/or size, observing the guidelines in the answer. The creation of static and crackles indicates that you have gone too far. If you can't get a setting which satisfies you, the solution is to install the Fluidsynth backends. This process is described in the first topic of the ADDING page of this website.


3. I am getting no sound. What can I do?


There is no one simple answer, because there are too many variables.

If you are using Windows, you may find it helpful to consult this topic within John Reimer's INSTRUCTIONS pdf* (pp.2-4). Although written for the BALMAIN VPO, it is applicable to any jOrgan disposition. Click HERE. If this doesn't tell you what you need, you can register for the Mailing List/Nabble Forum and ask for help. See the CONTACT page for details.

If you are using a Linux or a Mac computer, the problem may be rectified simply by altering the Audio Driver entry in the Fluidsynth Properties. With jOrgan running and a disposition open, go into Construct mode. (Click on the jOrgan "Construct" icon, which is found at the top left of the screen, immediately below "View" - it is the 3rd icon from the left. "Construct" means "build", and it is the mode to use whenever you wish to make changes to the disposition. But no sounds are possible until you come out of the Construct mode by clicking on its icon once more). Follow the advice given in pages 2-4 of John Reimer’s INSTRUCTIONS pdf* (click HERE). If you still have no sound, follow the advice given above to Windows users, regarding requests for help via the Mailing List/Forum.


4. Can I use a touchscreen with Linux?


If you are having problems, or are simply wondering, there is a webpage on the Ubuntu site which may help. Click HERE.
