An open arranger is not that much different to a closed arranger as it relates to customizing it to your needs. Except that the open arranger gives you more options.


Some one may be able to take a converted style to a G70 use make-up tools and get a good sounding style in less than 15 minutes.
Another person could do the same thing and take 30 minutes and not have a good sounding result.

It all depends on the person.

Now it does not appear that if you play using styles 100% taking the MS from the box straight to the gig is not the intended use.


Even if you play using styles, I am sure everyone does something to customize a new arranger to their unique playing style and gig requirements.


Whether closed or open, one should be spending a few hours customizing the keyboard to his or her needs initially.
From there, whether to use an open or closed arranger depends on the skill level of the user.
