I need advice.

Keyboard: Jupiter 50 keyboard http://
Computer: Macbook Pro
Speakers: Genelec 8000 http://

I would like to connect my Keyboard And Laptop to speakers or headphones, so that i could listen to sounds from my laptop and play and hear my keyboard at the same time. Either through heaphones or speakers.

How would you do it?

A mixer like this one

with the correct cables should work for you.
You might be able to run the keyboard into the laptop with USB and mix and monitor on your Macbook with the right software.
