Step ree - Describe the Notes Correspondence for Each Keyboard and Pedalboard

If you are using separate MIDI keyboards like the one in Chapter 4, each MIDI note is already described correctly to jOrgan and there is nothing else to be done; you can simply begin playing. However if, like me, you did your own keyboard wiring into a MIDI control unit that feeds your MIDI-USB device you may have some more explaining to do before jOrgan can make sense out of the notes coming from your various manuals.

Take a look at what jOrgan considers to be a complete keyboard, the one that is portrayed in jOrgan’s window, Fig. 5.3.

Fig . 5 .3 - jOrgan Full Keyboard

Note that the keyboard in Fig. 5.3 is a full 128-note keyboard. Its notes range from ve octaves below middle C to ve-and-a-half octaves above middle C. As initially represented in Fig. 5.2 the lowest note is note 0 and the highest is note 127, that is 128 in total.

If your organ keyboards are regular 61-note organ keyboards like mine, then your lowest note is only two octaves below middle C. So when you were wiring your MIDI boards, if you wired your lowest keyboard note into your rst MIDI board position, jOrgan will think your lowest note is actually as much as three octaves lower than you meant it to be! at means you must tell jOrgan to transpose as much as three octaves (36 notes) higher.

In my case I discovered, by trial and error, that I had to enter 24 in the transpose parameter space for each keyboard manual—Great, Choir and Swell. But the transpose parameter value for the pedalboard could remain at default 0 because the pedalboard is already two octaves lower than the manual keyboards.

Now click Finish in the Customize window and start playing your keyboards and pedals. You are set up to go with all independent keyboards and pedals, just like a real wind-and-pipe eatre Organ or Classical Organ!

A side note: you have probably wondered if there are other possible uses of the Customize Keyboards, such as might require changing the “From” and “ o” parameters. es, there are. For example your real organ keyboards are only 61 notes wide which means you might want to wire two of them into one channel. ou might have the Great occupying channel 1 from 0 to 60, and the Choir occupying the same channel 1 from 61 to 121. By now you have probably thought of other combinations, depending on how you wired your own keyboards. e capability is there, in jOrgan, if you want to use it.
