I like having the SEQ files myself.
Then you can have a mix and send a click/drums, synth/guitar patch changes as well .. even lights can use the MIDI data.
Having both MIDI and Audio available is nice.

That said, test the system you'll rely on many times before an actual show <grin>

If you don't need MIDI at all, an MP3 list can work, but will be a little less powerful.

Maybe Silvertones will chime in .. he plays solo shows pretty regularly using the Jukebox feature if I recall correctly .. you may want to look at that too


/personally, I have created SEQ files in RB, but used PT in live performance as it is lighter in resources (doesn't auto-load accompaniment features when opening files etc), and PT can open/use RB generated SEQ files
//we've also recorded multitrack performances live this way; playing a SEQ file in PT while recording our performance .. not recommended for the faint of heart or ill prepared


Make your sound your own!
.. I do not work here, but the benefits are still awesome
