By todays technology, the Musical Keyboard should just be an INPUT device. It shouldn't need CPU, memory, floppy disk, hard disk, display screen, programming buttons or knobs, input ports, sound chip.

ALL of those things belong in the computer. It should be very easy to DOCK a portable PC into such a device.

That type of device could then ECXELL in expression knobs, a good row of big illuminated preset buttons, draw bars and ways to do some live percussion.

The cost of putting those goodies would easily be offset by removing all duplication mentioned before.

Yes, quality of sound would greatly improve. Pedals, speakers, everything would connect to a UBus or to a FireWire. With speakers now being 'powered type' wireless digital signals to them would mean no cables and much more liberty on placing speakers. No big cables to carry either.
