Could someone explain the sys ex dump thingy to me.. i have a xp-30 that i want to use with cakewalk.. i set the instruments up all fine in a performance setup on the synth.. and make a song.. then i turn off the synth and my setup is gone.. isnt there a way with sys ex or something that i can first "record" the setup on the synth?

If you can guide me with this, I will be eternally grateful and sprinkle you with flowers.
