The midi messages you need to "remotely" control your current hardware my be quite complex, also you will only be able to control aspects of the keyboard that have been explicitly designed in by the manufacturer. Some things you can do with button presses may not actually be controllable via midi.
Nah, it's not difficult at all. With all due respect

I have used all of the arrangers and its pretty much the same on all. All the parts have a specific midi channel, so will respond to any midi messages on that channel. All the controllers send the entire list of CC numbers on whatever channel the user designates. And the latest controllers also use the CC's for GM 2.
As for the button pushes on the actual keyboard, they all link back to either sending a CC internally to the sound generator, or a Sysex message.
If Midi-Ox is used and the keyboard transmits to a PC, all these Sysex commands can be seen. They can then be copied into a sequencer, embedded into a smf, to mimic the keypress action, but "behind the scenes" as it were.
It's not as difficult as some people think. MIDI is not an arcane science, pretty much logic and common-sense.
Don't curb your enthusiasm Nick, go for it. That is the way we all learn.
As we have discussed privately, you can see what can be achieved with the Korg OS, add a controller and you will only be limited by your imagination
