I fully agree John...
And there is a reason those people inclined on arranging (and sound edditing/creating) turn to Korg. And thats because Korg arrangers come with all the tools to do so (except a piano roll editor) inside the instrument...
There is also different levels in his creative process. And my pa4x comes with all the tools for those different levels, from simply tweaking the volumes to replacing full tracks with self played backings. .. or from just edditing th ebasic parameters of a sound to creating whole new sounds from scratch.. and you don’t even need to load. New samples for that, as these imstruments come loaded with everything you need..
Now, that is said, i must admit that i prefer the sound of many of the Yamaha instruments.. and now with the Genos they made another step... but when i asked for these features that would allow for the same depth of arranging on Yamaha Genos as available on the pa4x, i was totally misunderstood by many of the as you said typical Yamaha arranger players.
I still think its a pitty..
I hope your pa1000 will soon arive, to challenge your creative processes...
