Wow Dave,
that is one heck of a setup.

Can see why you would want a seperate keyboard to be able to just pick up and go to work. Not doubling up on what you already own, makes a great deal of sense. I ended up with 3 korgs, but only because I didn’t try and sell any of them,
put it in the “ too hard “ basket , wish I had, because selling them , didn’t prove to be a problem in the end.

The last thing you would probably want to do is have to unplug an existing one and take it to work, then put set up back together again.

Enjoy your new keyboard.
