Hi Doc If you are a informatic engineer , the PA1x O.S. should have no problems for you,it is not that difficult.
Know that the PA1x use a touchscreen LCD and you like it or not.
I can say that the styles and sounds on the PA1x Pro are outstanding.
So is the keyfeel, fader control and HD (only on the Pro version)
I play also only for hobby and use Logitech Z - 2200 pc speakers or a headphone.

But be sure to update the O.S. to version 2.5.
