Looks like the profire2626 doesn't have midi input so i would run USB from the drum pat to your PC. Make sure you have the latest drivers for the drum pad.
I also have an eleven rack. I used to hook up my Spd-sx to eleven rack so i can record my drums and it was really time consuming. If only I know how to hook up my eleven rack ( enslaving eleven rack) to profire. itll save me so much trouble. any ideas?
