I use one Registration Bank per song. BUT, I start with a Registration that has 2/4 Country on Reg. 2, A Waltz on 3, a slow 4/4 on 4, a Jazz shuffle on 5, a 6/8 Slow Rock on 6, a Latin on 7 and a Rock n Roll on 8. In addition I put my most used sounds on each. In other words, two is a Pedal Steel, 3 in a Fiddle, 4 is a Piano, 5 is a Jazz Guitar, 6 is a Sax, 7 is a Harmonica, 8 is a Strat guitar.
THEN, I set the Freeze function so that when it is on, the only thing that changes when I push a Reg button is the Sound. Not the style, not anything but the sound.
So, say I have the setup for Mustang Sally on one. It is set to pull up whatever sound I like, like Organ, plus the appropriate style for that song. Then I hit the Freeze button, and have the eight sounds to use on the song.
I use the same seven extra sounds on every Registration. In addition to having Mustang Sally ready, with which I can use any of those (or any of the OTS associated with each of the other pads) but I can end Mustang, take the Freeze off, press number 6 for example and be playing a Slow Rock ballad in one second or less.
I save all the Registrations with Syncro Start on.
In conclusion, for each of my songs, one to a Registration, I have eight sounds, each with their own set of OTS, at my disposal, PLUS the seven other go-to song setups.
By saving one main song to its own Registration Bank, the Banks are automatically saved in Alphabetical order, by song title, or whatever you want to name them.
You can press both Reg Select buttons at the same time to see your list of Banks (songs).
Find the song you want, select it, press button one with the Freeze Off, then put the Freeze on and play the song, using all the other buttons to change sounds. The process quickly becomes automatic.
That's just the I do it, and thought it might help someone. Even Donny. HEE HEE!
