I am one who advocates the "read the manual" stuff before asking on a forum, but somehow I'm not getting "it" here. I use Mp3 backing tracks and on my Korg PA700, I simply load the mp3 on the disk and it opens up and plays. On the Genos, not sure what I'm doing wrong, but I can't get the board to see the audio files. The disk is fine, because my extra styles, mid files, multipads, etc all load ok. Is there a different format beside MP3 I need to use ? I tried wav files but to no avail...
