I 'm a ex-X3 user (1993-97)so what's your question.
things to consider-
X3 can't play direcly from disks(it has to load it-int mem is 32000 notes(ie-4-5 SMF max)
Transposition written in x3 can't be recognized by other gear(only specific for x3)
all sounds are decent(even to today's std) except ac piano
sequencer is not hard.though it has a small screen -it has dedicated buttons
bottom line-Good KB for studio or live with band
not for solo players/gigers.
check n364(more poly) sites cause seq is identical.
