Hi Rog
Voice editing, I've never really been involved with, I was silly enough to put together a sampled Ketron live drumkit for a single style i 'd converted, an orchestral swing. Really luved that style.

The style editing/creating I s brilliant in the Korg's. You can copy style tracks to pads & vice versa. You can export the style as a midifile to a sequencer for editing. Unlike with the Yamaha , each of the style tracks can be event list edited in the keyboard itself.
The list of stuff that can be done is pretty amazing, and I don 't even have the song to style convertor in my pa3x(darn).

Great to hear you 're enjoying your korg, if you need any extra styles ( prior korg keyboards) you 're welcome to have a copy.
