This section of the website deals with various additions which are available to enhance one's use of jOrgan, once a start has been made.
When using Windows versions later than XP, Fluidsynth backends are needed to improve latency. They also make it possible to access ASIO devices, including third-
Graham Goode has written a number of tutorials dealing with this general topic, all found on the Tutorials page of the jOrgan InfoBase. The first shows how to install the Fluidsynth backends on your Windows computer. Click HERE, but firstly bear in mind the following explanation:
Two sets of downloads are offered, and it is recommended that you use those by Graham (rather than those by BCA), and specified as “ALL”, as you then don't have to do separate downloads. You do of course have to get the 32-
You may find the abbreviations off-
ASIO Audio Stream Input/Output
WDMKS Windows Driver Model Kernel Streaming
WASAPI Windows Audio Session Application Programming Interface
JACK Jack Audio Connection Kit
The download is a zip file, and you will need to unzip it. You will find that it is then a single folder. It needs to be placed within the “fluidsynth” folder, found within the “lib” folder of the main jOrgan folder which is located in the “Program Files (x86)” folder if 32-
You should follow carefully the instructions there which follow, bearing in mind that you cannot expect to see exactly the same details in your installation (which uses Graham Goode's “ALL” download) as those details which are shown in the various screenshots. Don't be confused by the fact that those screenshots portray a situation where there are multiple instances of Fluidsynth being used and multiple audio channels.
The tutorial shows how to configure jOrgan for the use of the backends. Note that after making any change in the configuration, you need to exit jOrgan and restart it, for the changes to take effect.
Having made the change, you now need to alter the Audio Driver entry in the Fluidsynth Properties to reflect that change. Go into Construct Mode for that. This has to be done for every disposition you open and with which you intend to use the Fluidsynth Backends. In most cases, “portaudio” is the driver you will enter from the drop-
Once you begin to play after making this change, you may find that you need to increase the size of the audio buffers (use the last page of the Customizer), in order to reduce any sound break-
Most users will desire better reverberation than that provided by Fluidsynth. There are available some excellent programs which can be used with jOrgan to achieve this, some of them free.
Graham Goode has written a tutorial to help you install one such program, the ReverberateLE. This is a free convolution-
Graham has also written a tutorial explaining the use of the ASIO4ALL program. You should read that tutorial and follow its instructions. Click HERE.

You will need to refer to Graham Goode's tutorial on installing JACK for Windows. This tutorial was written quite some time ago, and Graham is now advising a different link for the download of the Windows version of JACK. Graham has reproduced much of the material from that JACK website in his tutorial, but it would still be a good idea to read it from that website as well as from the tutorial.
Note the following sentence under the heading, “Windows XP 64-
“The official release of Jack for Windows only supports Windows XP and Vista in the 32-
