playing Wav from USB

[jabberwocky]

Are WAV files from the USB played directly from the USB, or do you need to load these first into the memory of the sonic cell ?

Just looking for a device playing some backingtracks (wav) when I have to do music in churches, so I can play Piano live over it. (and the 2 extra SRX slots might come-in handy also).

WAV files can be played directly from the USB, and are shown in Playlist Libraries (like the mp3's)
