Donny, the only problem I see with that setup is the number of individual components that have to be stored separately, power supplies, laptop, laptop stand, cables, mixer, mic, etc...
With the console setup, all of those components stay with the console, including the cables and pedals. The only separate cable is the output cable that connects from the keyboard to the amp. In your setup, where you use a mixer, only one end of the output cable would have to be plugged in with a console setup. The other end would remain plugged into the mixer at all times. Same goes for the mic cable.
Over the years, I have constructed a dozen consoles for individuals throughout the US, and to my knowledge, every one of them is still in use today. And, at least another dozen or more have been constructed by musicians using the directions I posted on the PSR Tutorial site. Two are being used in Mexico and one in Australia. The one I had in my office/studio just got shipped to a friend of Don Mason's in LA.
Hope to see you next week,
Gary
