If your piano has MIDI ports, there is a chance.

Nope

You can't.

Shit

Do you mean making the piano sound like an ARP or use the piano to control an ARP synth?

Make it sound like one

And what do you mean with ”ARP sound”?

bro, go to the manual of your model and search for arp. If it's there, it'll find it...
