KeyFax 'Vintage Keys' Libraries for Yamaha MO6?

[Oregone]

So I've been a loyal MO6 user for years. I use it for synth & clav, as well as EP when hauling Rhodes or Wurly is not an option. I really don't care for the Clav sounds that much. I was looking into the KeyFax 'Vintage Keys' libraries available thru Motifator, and was curious if anyone had any real world experience with these? Are they worth it? I have listened to the demos on their site, and they sound good? Thoughts?
