The engine inside AN200 is simply the PLG150AN card. Hence An1xEdit works fine with the AN200, since it fully supports the PLG card.
However AN1xEdit does not cater for the drum tracks of the AN200.
Note the AN200 is supplied with a modified version of the PLG150AN editor for Yamahas XGworks. I believe this editor does also cater for the drum parts. Either way you will be able to use AN1xEdit files.
Thanx a lot for all this precious suggestion about the An200!!! Just another question: Is it possible to use the An1x editor on the An200 or it has another editor who don't accepts the An1x voices? Andrea
