First of all you have to make an important decision and that is:

1. Keep the all the analog stuff

2. Junk the analog stuff

I own a Trio and after some serious thoughts I decided for item 2. One reason is that I have had the Trio for 30 years and got somewhat tired of the sound and the “innovative†disposition. The other reason was that a friend of mine who is an analog fan could make use of all the leftovers.

If you decide for item 2 then you will find that the Midibox with the MIDIO128 application is the ideal thing. I have midified all the keyboards, pedal, all the stops and I have now 35 pistons, also midified. I have used three cores and DIN’s with 128 inputs each.

If, on the other hand, you want to keep the analog stuff it is still possible to use the MIDIO128 but additional circuits are needed. I think you will be better off using applications specifically geared to the Rodgers Trio.

The Trio is the perfect candidate for Midification.

To use MidiBox MidIO128 you just need a switch contact for each note and pedal to get to base 1 of Midification.  To be more precise, you need a voltage free switch contact which just means there is no other circuitry connected through that switch.

Most older analogue organs have many switch contacts per note.  Often 1 for each of the voices available on that note.  When Conn organs updated their circuitry in the 1980's they were now using only 1x switch contact per note and left all the others spare.  That makes the Conn 650 series organs the easiest to Midify and still keep the analogue organ function.  For other analogue organs you can add another switch contact (the easiest way is probably using small magnetic reed switches), or disable at least 1x switch function from the analogue circuit.  (there may be 1 analogue voice you can live without without dumping the lot).

Other Midi systems will cost 10x times more than MidiBox, or will have functional or expansion limitations that will only come to light when you feel the need to add to your project.

I have used MidiBox to Midify a Yamaha E5AR.  I am now looking at ways to add a third keyboard.

Best of luck with your project.
