My operating system is now Catalina (10.15.1).
I tried to get and install an appropriate driver from Yamaha, but alas, I couldn't find any on their web-site.
Roland, by contrast makes it very easy to upgrade its drivers so I got it to work just fine.
But I love my Yamaha! Its fun to use for improvisation with all the many voices it has.
Now for my question:
I see on Amazon that Roland 88 key digital pianos can be had for around $600 bucks. But can they be used for entering notes into Finale 26etc on a Mac?
