Hi Nick,
were they sampled voices or rom voices. PA500 as you're probably aware doesn't load samples.
Wouldn't advise loading PA800 resources in a PA500, could cause a problem.
http://www.korgpa.com/pa_root/en/products/pa800_soft.html?enIf you're loading a Resources file it has to be for your specific instrument as it overwrites the Factory Data.
I would imagine John would have one specifically for pa500.
John Smies has made some great saxes.
I tried his resources on my PA 800 and one of the biggest outstanding highlights for me was the sax voices.
not sure how they will sound on the PA 500 - should be the same if not VERY similar to the PA800.
Nick
