Using the Customizer
Navigation: Go to End of Page
The Customizer allows you to adjust the currently opened disposition without the need to get into jOrgan's details. It contains a number of pages, each devoted to a separate aspect of setting up the disposition so that it works well with any external console or keyboard(s) you wish to use.
To access the Customizer, click on “File” and then on “Customize...”.
Keyboards
For each keyboard (if desired) select a wikipedia:Midi device using the Device scroll arrow and click on “Record”. Press briefly the bottom note and then the top note. This allows jOrgan to record (or “register”) the MIDI channel and the keyboard MIDI note range being used. The results are displayed at the right. Alternatively you can set those details there manually. Note however that MIDI Channels 0 to 15 are registered there as Channels 1 to 16, and this protocol should be observed if you are making the settings manually.
Console
If the Screen window is empty, select whatever screen indicator you see when you use the scroll arrow. This indicator will be appropriate for your computer OS. If the console does not fit your computer screen to your liking, use the zoom provision to adjust it.
Connector
Use the scroll arrow to select the wikipedia:Midi device being used to to receive MIDI messages from your organ console or keyboard(s). This page will allow the disposition elements to respond to MIDI messages whenever they are received. These are mainly stop switches, combination pistons and continuous controls of one sort or another, notably swell controls. (The disposition creator has already prepared those elements by referencing them to a connector).
Stop switches and pistons and other switches are grouped under the tab “Switches”, continuous controls under “Continuous”.
For switches, click on a table cell (Activate, Deactivate or Toggle). A “Recording” window appears, which is telling you to operate the organ console switch appropriately, in order to send its MIDI message and have it recorded (i.e. registered). In response, the window disappears, and a small yellow icon indicates that the message has been recorded. If for any reason you wish to delete a message that has already been recorded for that cell, simply click on “OK”.
For continuous controls, the process is similar except that after clicking on a cell you are expected to move that control slightly. Each time a MIDI message matching that already recorded is received, the corresponding cell will be highlighted in yellow.
Fluidsynth Sound
This page allows you to adjust two basic Properties of Fluidsynth without having to go into “Construct” mode. However, you probably won’t need to do this until you hear the sound and wish to make some changes.
Normally you should Save the disposition after using the Customizer.
