Hi Diki.
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...
In a way what your talking about there is like the KORG SNG file, only you have what seems external registrations and links to files. The SNG file contains everything needed, including very specific setups and even alterations to factory sounds without effecting anything else in memory.
For example, I could have very different Engine Filter Setups for a factory sound, and if two songs used the same sound, one would not effect the other and I would not be every overwriting anything or creating anything new that needed to sit in registration memory external to the song itself.
In short, one file does it all, as well as holding up to 210,000 notes or 128 songs (whichever is used up first).
Regards.
James.
