I admit that Roland seem to be the worst culprit when it comes to dropping things as well as simply adding more...

I have no idea why this is. Poor market research is where I'd first put it. I have NEVER been contacted by Roland in the 20 years of using their arrangers professionally!

Then they have ZERO customer relations. You see Steve Demming from Yamaha often come here and ask for input. Ever seen anyone from Roland here? Me neither
