It's not a deal-breaker for me...however I am annoyed with the fact that you cannot record a song utilizing a style which contains an audio drum track - either internally or via USB audio. The keyboard will automatically ignore any audio drums and record only MIDI voices. The only way around it is to play live and record via the L + R outputs to an external recorder. Maybe someone can correct me, but that's what I am understanding regarding this limitation. If this has already been stated by someone else, please excuse the repetition.
