Well my theory was blown out of the water wasn't it But the question is how easy would it be to play a guitar, sax, or any other instrument sound besides a Piano? Has anybody here been able to determine that? Also any easy portability is constrained beyond reason. The KF-90 is over 86 lbs. making it a real back breaker especially if you have to tote it around 3 or 4 times a week. And the Gem is not far behind at almost 75 lbs.

Wouldn't be nice if there could be a way to turn on a Hammer Action effect when playing Piano and turn it off when playing another instrument sound? The GC in San Diego might have the KF-90 on display. If they do I might check it out to see for myself how limiting a weighted arranger is on playing different sounds, (sax, guitar, 'violin', etc.
