James, my G70 will Link an SMF to the registration (UPG)... call up a registration, with everything you need for the keyboard parts already assigned (and easily changed without altering the SMF), and the sequence is instantly loaded. With a SSHD, there's no seek time or loading time.

Every song I do is instantly available. I see no better way than this to perform...
