Hello I recently purchased a new MacBook which is running Cubase Studio 4 and Reason 3. I am looking at buying a controller keyboard to connect with my MacBook and I intend to also purchase some form of audio interface. I'm trying to establish a set-up where I can trigger piano and string notes (in Cubase) by playing the controller keyboard notes in real time while my sequenced tracks are playing back. Im looking for an affordable yet hassle-free arrangement for my equipment during performances. Id welcome your advice and opinions Many thanks Spencer.
