Yeah, not the direction I would have preferred this to go. I received my AARP card at 50 and wasn't too happy with it. Mid-50s now and creeping up on that Senior Citizen label and I don't think your comment came across how you meant it. Hopefully.
There are a few professionals that sell sound sets for my Montage M8x. Super complex stuff - most concentrate on the deep AN-X analog or FM synthesis engines that are no fun to program. I've considered purchasing some of them because that stuff is was out of my knowledge area.
This stuff is pretty simple, however. But it wasn't always that way. I will tell you that I would bet Richard Noel spent over a hundred hours on that tiny screen editing every sound, moving them to sound banks, matching them to appropriate bass sections, etc. He is also a fantastic accordionist. It's been awhile since I've watched any of his videos but I've never seen him reference a piece of music, he plays any song flawlessly, and I would say he has a four or five hour repertoire without using any music. He's probably got 10-15 years on me and I'll never be that good of an accordionist. I believe somebody told me once he's a retired Doctor or Dentist, plays hundreds of gigs a year and doesn't need this money. He put those sets together because from his multiple gigs he understood how poor the factory sounds and sets were. He gave them to a few people, everybody wanted them and he sold them. This is all prior to the editor. It's unkind to think he's some kind of grifter or ancient out of touch senior. Anything but.
At any rate, I'd like to revisit the price of this machine. I thought it wasn't going to cost anywhere near $8000? It's $8K US everywhere I've looked. Maybe that's just the MSRP prior to actual release, but right now you're looking at around nine grand with taxes and shipping. Ouch!
I think the Korg will be fine out of the box. Luigi's videos don't seem to be rigged in any special way and sound great to me. And for those that want the value add of additional sound sets, perceived or not, good for them.
