Diki - you could probably read between the lines of what I was saying SHOULD be in the next line of arrangers from Yamaha as an absolute minimum :-) Korg comes close but still not on par with the Roland Make up tools...
I haven’t done any work on a Yamaha but have read manuals. But I have worked on editing a PA3X & PA4X. The biggest problem I found with the Korg’s is, if you want to do some simple editing on a drum sound, bring up it’s velocity for instance, you actually have to go in and do it separately for not only each Division (Variation, fill etc) but also for each chord type (maj, min, 7ths) of each of those Divisions. So, 4 variations, four fills, three intros, three endings, times three chord types!
A command that Roland does in one go needs to be repeated 42 times! Now yes, you can do a clunky workaround where you edit the ROM drum kit and save as a user drum kit, but now you are faced with a bewildering number of edited kits, as each edited style needs its own, using up your limited slots and making data management a nightmare.
And heaven help you because that’s the way it works on non drum sounds too..!
There’s a REASON why so few of us spend much time customizing our styles and sequences. It’s just too much bother… Except for Roland users.
