The Sonic Cell will only play a total of 99 songs from a USB thumb drive..They can be SMF's. wav or MP3's..but limited to a total of 99..
Also for live it is difficult to mute and edit files...your EM 2000 is a better way to play SMF's live..

I owned a Sonic Cell and was dis appointed with the file limitation...I actually replaced the Sonic Cell with a Juno G[999 file limitation..]..
