9. jOrgan with Music Notation Front End Computer
A music notation program can drive a jOrgan computer. at was the original premise of this chapter. It is actually a straightforward process, following the steps indicated below. However it is only straightforward if you limit yourself to transmitting note on/o messages. Dynamics, such as expression pedals, are extremely dicult to transmit from a notation program such as Finale, as are pistons and coupler eects. Side note: I have essentially abandoned this line of investigation—for now.
Technology—Two Computers with a (Hardware) MIDI Connector
e simplest way to do it, at least for me, is to use a multiple MIDI-in connector (probably the same one that
your MIDI keyboards use) to a single MIDI-out where your jOrgan computer is connected. See gure 9.1.
Fig . 9 .1 - MIDI Connection—Notation Computer, Keyboards, jOrgan Computer In the Fig. 9.1, my notation computer is a Mac running the Finale music software application, which has a MIDI-out capability. e Mac is connected to the same MIDI interface that receives inputs from my keyboards and stop rails. To jOrgan, it is immaterial whether the MIDI signals received on its MIDI-in port come from the keyboards or from the Mac. ey all look the same to jOrgan.
To me, in this conguration, it is especially useful that Finale can not only send note on/o information, but also send other programmable MIDI messages as well, such as Stop Tab On/O and Piston On/O. However, this latter capability is not essential, you can always set up jOrgan’s registration ahead of time, then start your notation program sending note on/o messages, and achieve the same efect.
is technology must be fairly simple and reliable because even I have been able to use it successfully. Here is a
link to a Christmas piece, my arrangement of “Now Sing We All Merrily”, using Finale on a Mac connected to jOrgan on a PC running Paul Stratman’s elegant Grand Concert Harpsichord disposition:
