Hi Bill,

Yes, I see your point.
I agree this combo will not work out for gigging musicians.

The Roland RD-2000 EX weighs 48 lbs. It is not easy to move around when you consider the extra weight of the necessary road case to safely transport it.

Next you would have to add the weight of the Roland VR-730 which adds another 21 lbs plus the keyboard stand. This could become unwieldy.

Weight is a very important factor for gigging musician. This could be one of the main reasons why the GENOS 2 weighing just 31 lbs is so popular.
