I'm pretty certain that the ADC series only outputs midi signals from the manuals and pedal, not pistons, swell pedal or individual stop controls. It wasn't until the next generation, the MDS series, that full midi was implemented, from about 1990 onwards. I think your model was built in the late 80s or early 90s just, which was right at the changeover unfortunately.
It is possible to add midi to these controls but it would be necessary to break into the wiring looms to fit an add-on midi interface. Alternatively it would be much simpler to use a touch screen (or two) for the controls, although it wouldn't solve the swell control, but even this could might be possible by replacing the orginal swell pedal with a modern midi type. I've found that Allen organ consoles are generally built using basic building techniques (wood, screwed together) and can be modified fairly easily, just steer clear of the electronics. That's one of the great assets of HW, in that all the old technology can be left alone to do its own thing, but in silence.
You can download a manual for the organ from the Allen Organ website, which used to be free but I believe they now make a small charge for older organs. I think it's found under 'Support - Maunuals - Older Organs'.
Hope that helps.
