The Trillium Keyboard Chart is based on a constant MSB of 93 for all the sounds. I suggest setting MIDI GT A, MIDI SW A, MIDI PD A and MIDI CH A to a sound that has an MSB of 93 and an LSB of 126. These can be any sounds of your choosing (or see my chart below.)

Then set all the "B" MIDI pistons to a sound that has an MSB of 93 and an LSB of 127. Again, you can choose which sounds you prefer or see the chart.

If you have one MIDI piston per division, use the suggested sounds for “A” pistons.

Here are some suggested sounds:

MIDI PISTON	SOUND	MSB	LSB	PGM
GT A	Cathedral	93	126	107
GT B	Chamb. Strings	93	127	2
SW A	Royal Trump 8’	93	126	16
SW B	Oboe mf	93	127	44
CH A	Viols Chorus	93	126	53
CH B	Flute	93	127	40
PD A	32’ Untersatz	93	126	55
PD B	Bass Pizzicato	93	127	11

TO SET THESE CHART SOUNDS or YOUR FAVORITES

1. Hold SET and press the desired MIDI piston – it will flash

2. Release all pistons

3. In the window for that MIDI piston set the MSB, LSB and PGM number with the Alpha-dial

4. Touch the MIDI piston or tab so as to turn it on – it will stop flashing and the sound should be there

The real secret is that when you have set all the midi pistons, one at a time, to these or your favorite sounds, do a MIDI Save procedure. This will save these sounds as defaults so they will be there when you turn the organ on.

To do this, you must be viewing one of the MIDI piston’s settings in the organ’s green window. If you are not looking at a MIDI window, hold SET and activate any of the MIDI pistons – it will flash. Now touch it again as if to turn it on and it will stop flashing. You can now proceed with the save procedure:

Hold SET and while continuing to hold SET, press and hold GEN CANCEL for as long as it takes to see the message that the settings were saved (about 5 seconds). Now you have all "A" MIDI pistons with an MSB of 93 and an LSB of 126, and all "B" MIDI pistons with an MSB of 93 and an LSB of 127.

Note: Be sure to set the VELocity to KBD to make the sounds respond to touch. Organ sounds are not velocity sensitive!

NOW PRINT THE KEYBOARD CHART AND CONTINUE BELOW

TO USE THE KEYBOARD CHART

1. Find the name of the sound you want

2. Find the key to press to get the sound
On the Keyboard Chart note that:
I = Bottom Keyboard (GT on 2-manual, CH on 3-manual)
II = Next keyboard up (SW on 2-manual, GT on 3-manual)
III = Next Keyboard up (PD on 2-manual, SW on 3-manual)

Is it a 126 or 127 sound (the LSB)? If the sound has a “-7” to the right of its key name it is a 127 sound (see the legend at the top of the chart)

If it is a “126” sound use an “A” MIDI piston

If it is a “127” sound use a “B” MIDI piston

3. Hold SET and press an “A” MIDI coupler for a 126 sound, or a “B” MIDI coupler for a 127 sound – it will flash

4. Release all pistons

5. Press the key name – the MIDI piston will stop flashing

6. Play the sound

For instance, if you want Grand MX under PIANO, put it on any “A” MIDI piston. Since “A” pistons are already at 126, and Grand MX is a 126 sound, just hold SET and activate the desired “A” MIDI piston and it will flash. Release all pistons and touch the second D# on the second keyboard from the bottom (the SW on a 2-manual, the GT on a 3-manual). The sound should be there.

Can you put a 126 sound on a “B” piston, or a 127 sound on an “A” piston? Sure! But of course this adds one step of setting the LSB to the new number. You can have any LSB you want on any MIDI piston. The method discussed above just saves a step.

Save your sound in a piston if you want to have it available. Remember, doing the MIDI SAVE procedure above is for the organ’s default settings for the MIDI pistons. Those are the sounds that will be there when you turn the organ on. It is a good starting point. If you select other sounds, save them in a memory piston.

I suggest ordering the book on the MX200 for the Trillium Organs from Frog Music. It will make all of this clear. Many thanks to Noel Jones of Frog Music for his valuable input! Here is their website:
