Hi Beaky,
For instance, I have a slow and a fast Bossa in my collection, BUT, really no way of telling whether they’re the same as on cvp ( but with audio, by the sound of things) without checking both.
When I was sorting thru those 4000 to 5000 styles, I noticed that, not only did yamaha change the category of some of the styles ie they might move a world to an entertainer, the odd Latin got moved around too, (which complicated things a bit) but, on the odd one , they even changed the name.
Ie on one keyboard it might be 8 beat 1. On another it might be 8 beat 2.
(Love to have a copy when you finish.)
