Hi Donny,
not the same thing. Comparing apples with oranges, really.

VA2, is designed to play styles from different manufacturers.
Groovyband Live looks like it’s designed to improve styles and functions on Yamaha keyboards, by giving them a new engine.

I’ve downloaded it, not sure what difference it would make to my sx apart from giving extra variations. I haven’t had a chance to actually try it yet .

Must admit I was interested if I was able to use it with my p121 as controller and the sx as sound source, but unfortunately then discovered I couldn’t use my User styles,
( unless I misunderstood something) some of the psr factory styles I use are missing from Groovyband .
Plus I will be modifying a number of the factory styles on my sx, I copy and paste style tracks. If the resulting styles can’t be used, software isn’t of any use to me.
