Hi Adimatis,
after 3 months or more, I'm still discovering settings & stuff this keyboard has & can do.
If somethings not working quite how I'd hoped, there's usually a solution or setting I've missed somewhere.
For instance I luved the OTS settings on my psr1500, the way the melody sounds change with each variation.
The Korg has the equivalent called STS's only thing was, mine weren't changing with the variations.Took me a while to realize the Single Touch setting button had to be flashing for the STS's to change with the variations.

Amittedly you're still stuck with 2 fills,+ break, but being able to direct which variation they're going to affect makes a big difference. With off they do a self fill, you can send them to variation 1 or 2 or 3 or 4, they can step up or down increments, you can set one up to do vari1 & 2 or 1 &3 or 2 & 3 any combination & they & it the fill alternates between the 2 chosen variations.
The beaut part is it's not a global setting that affects all the styles , but a performance setting that affects a single style.

Personally there's a couple of reasons I wouldn't have bought a Roland again.
No Pads, they're brilliant the way they work in the PA800, the sync options are better than in my psr1500. It has one additional one.
I beleive the pads on earlier Korgs were fairly ordinary?? Someone told me they improved on the PA1X??
And Roland as far as I'm aware still doesn't have a percussion track?? For me the fact that I like to be able to convert styles, would make it a bit more difficult because all the other major keyboards as far as I'm aware use percussion & drum tracks. Trying to cram them into one track would make it even more difficult to edit drum velocities & non gm standard drum notes.

Obviously Korgs don't suit everyone, but if you're planning on changing keyboards, might be worth a look. Download the main manual first & have a look thru. There is an extended manual on Sound editing & the Audio Loop Groove functions for drum tracks & pads.

best wishes
Rikki.
