4 me right now, sound is primary because I just play...& I wasn't very pleased with what came out of the Fantom X (piano)..but i guess that's bcos 1 didn't mess with the board enough to get the "right" piano sounds.
but 4 other features, yeah, there must be a great deal one can do with those boards that an ordinary player like me doesn't make much use of.
Experts out there, please motivate for me why it would be cool to have a Motif/ Fantom coz I do want to see the full capacity of a board I own, even if it's jut for fun..
Polyphony is 1, but like TMR stated, the Juno G is a 128..so what else do I really need?
