Diki you have to visit the Korg forum. There are people who claim that the PA's including my PA500 have the exact editing possibilities then a M3. The only difference is that the M3 have more insert effects but this problem is solved with the PA3x. And yes it can load Triton sounds but that's the beauty of a Korg PA it can sound different. For example I have the Musikant which sound very different then the normal PA500 but it can also sound like the normal PA500. It is all about sound editing.
