fill-ins in korg's arrangers were always like that: little bit out of sync, erratic and only two of them.

even tho the korg sounds are so good, i found the styles in roland (especially new e series) to be perfectly balanced between very "correct" (yamaha) and "funky/live" (korg) and so, i prefer roland.

when i had my korg, i didn t like it had only two fillins, and i hear now is the same, even if theoreticly now there are three of them.

but nevertheless, pa800 should be a gooood keyboard to play with. congrats!
