The Lionstracs Mediastation and Wersi OAS instruments both play WAV, AIFF, MP3, MP4, and Video files as well. It's a fantastic feature. The Mediastations dual Audio/Video players are especially nice.

It's a good thing to see Korg bringing an option to the PA series that many users will get lots of use out of. Uncle Dave included.

Does the Korg MP3 board allow for any real time Pitch Shifting or Time Stretching of the audio files? That's something the Mediastation does and does very well.
