Hi Graham,
meant to actually ask ( on the korg forum), are you mainly trying to convert just the odd style to PAxxx format, or were you hoping to do a heap of them.

The conversion process can be time consuming depending on how the conversion turns out. It's the editing after the conversion that may take time.

I've got a few that I really like on my psr1500 & there isn't an equivalent style on my PA800.
For those styles I'll spend the time and edit to get them right.
Others I just run thru my emc & if I need them one day , I'll tweak them.
best wishes
Rikki
