just as diki said it before, once you learn what the buttons can do and how you can combine the actions, does not matter their number.

IMO, korg's better with "fine-tuning" giving you more options when you really go into it. but roland give's you the basic options, so you have it done sooner.

no one can really tell what's best for you. read the manuals, read the forums, you already test them both... now you decide.

and the last thing: korg still have the issue with smooth fills. meaning they are not smooth, you have to press the fill buttons with a better precission to avoid the hiccups. roland it's way better at this.
