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 dicult to transmit from a notation program such as Finale, as are pistons and coupler eects. 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 conguration, 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 efect.

  • 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:
