NO...never tried the G70,,Even did a 4 hour road trip last week hoping to play one[Ask AJ]..
Proud or disappointed...only when it comes to family or friends..
I really don't care if it's Korg, Roland, Yamaha, Gem, Ketron,....even if it was Siel...If I like it , I will use. If I don't, I won't..

The reason I support particular Roland boards is because of the quality construction, and features that work the best for me..
There is a long list of boards I did not like well enough to keep..including Roland[Fantom X as an example]...Doesn't mean the board isn't a great choice for someone else.
If I am dissatisfied with the G70 or E-80, or any board [even Yamaha]..I will voice my opinion, as I always have[in response]..

Yes, buying a G70 as a controller...I was kidding.
