You can. You will need an adapter/cable if your midi controller doesn’t have a midi out via USB. Other than that you can easily get any Rig that is on your Player by sending a PC command using number: 0 through 49 on whatever midi channel your Player is set to (default is channel 1 I think)
That's very good news. I'm sure that's going to be the way for a lot of people. They can leave the Toaster at home and play live with the Player. And when the upgrades come...
Great!
