Comments from someone that never played a G 70.
After several days of comparing the Korg pa4x to the Roland g70....Final results...g70 easily beats the pa4x..
Sounds like scat, choir,piano and electric piano, are horrible compared to g70.
Even organs are better on g70...drums too.

GM sound set leaves a lot to be desired on the pa4x..
OS is a nightmare on Korg ..compared to the ease of Roland g70..

Anytime you want me to prove the above facts..call me..breakfast first

After this week with Roland the winner in the above categories...I bought a Roland e-a7..it will be here in a couple days..mid line Korg and Yamaha, just won't cut it...
