Hi,
that could well be the case. It certainly was for tyros styles played on my S950 . I could have fixed them, but most of the time I didn’t bother unless I needed it.

The T series does appear to play pretty well on the sx though, a think the scat voices on the sx, may have solved some of missing voice problems that the earlier psrs had.
Again, only worth checking if I need a particular style.

A lot of the Genos styles are on the sx anyway, so if there’s an odd one I want, just have to try to tweak it.

Just handy to know there’s extra styles out there, if there isn’t a suitable one in the sx.
