Hi, Since the heavy hitters have weighed in, I can tell you how I converted an Allen TC4 circa 1959. I am a retired Telephone office repairman, so I understood the challenge. I got my console from a junk pile, complete with an abandoned mouse nest. This is tedious and time consuming. You can purchase a 2 or 3 manual stack already equipped. This project gave me an AGO console with a touch screen, and 8GB Dell for $1200. If you still want to wire..... Try step 2 first. If you can't figure out the terminal strips, get help before investing in the MIDI encoder.
1. I selected the MidiBoutique HWCE2 bundle #3, which could handle a third manual of the "old style"..
2. I used a shim to keep one key down and purchased a simple circuit tester, the kind with a probe with a battery and light bulb in the probe. The back terminal strips ate labeled with C notes. There are some relays at the left (from the rear) that move mechanical sliders. I put a small zip tie around the relay and tested to find the terminal strips to get a light. It sounds complicated but I found that "DIAPASION" terminal strip 4th relay slider from the front, works on the lower. FLUTES second slider from the rear works the upper.
3. I stripped out the drawers of discreet components by cutting each wire that went into the wiring harness, at the drawer end so as to conserve the wire. The end that goes into the rear of the terminal strips from the drawers, I cut the whole cable at the end of the terminal strip I used these cables for wire to assemble the (included) cable plugs for the HWCE encoder.
4. The pedal cable can be wired as stated in the instructions. The swell shoes took some engineering, but use an off the shelf Pot and gear/track that are available from web sites. IF you male it this far, you should find the terminals from the PRESETS and wire them to a spare HWCE position on a encoder.
5. I found the View Sonic 23" touch screen on Tiger Direct for $249 .
Good Luck
