Today I'm going to try hooking up my Casio CTK-4200 AD hardware keyboard to Ableton with a USB cable and using its MIDI capabilities. I just searched for "playing MIDI through a Casio keyboard" in Google and it says it can either receive audio or send it to the laptop. What I'm imagining will happen is either the notes output will play on my Casio speakers, or through the laptop speakers. I don't have my monitors rigged up to the laptop anymore as there's not enough space. This will be fun - I can't wait to find out if I can play those STS synths via the Casio keys, as it's so much more tactile and I have over 5 octaves.
