i do love my g-70, but the merengue, cumbia, salsa is a JOKE, not even close to th real deal... i could bet my life on it that it was not a "latin" player programming these styles...
yes the G-70 is built like a tank, and is heavy as hell.
as far as Ketron, it just sounds so much punchier, full, more live than my G-70,
i have the XD-3 module, and the overall sound through my QSC PA, is amazing.
i think it's the Ketron live drums, that really make the difference
i'm liking the Tyros3 sounds alot, and i just may have to get it.
imagine that a 3 tier stand with the G-70, Tyros 3, and Ketron XD-3, the best of ALL worlds
