Thanks Ian , for the added info about the styles , maybe thats it , the voicing , being a different kind altogether would affect the styles. I should have another look I think !!

Yup !!
Those huge "roll bars" on the X4500 were something , I found that it actually worked quite well , once you got used to it. But still , I had notes dropping all over the place !! LOL
They could have given it at-least 16 poly !!

Hi have tried in the past to find that 1 blues style from the 510 , and so far no luck , some that were close , but not the exact style , my search continues.

Well thanks again, take care.
Gary
