Someone asked a few days ago why you need that many sounds. Now my question is why do one need so many styles. Be creative just use the onboard tools of your arranger to make the styles to your liking. No need to buy expensive software if you already own an arranger. Just be creative just like in the old days when arrangers only had about 100 styles. Just my opinion of course.
I agree Fran no need for so many styles....
probably 50-100 or so could handle most any song.....
and with that you can change sounds, parts,
and edit & tweak to suit also with no problem.
