From what I understand, the SD40 is basically an SD7 in modular form. Since you choose not to use registrations, how are you saving "snapshots" of your settings now? I don't mean GLOBAL,but instrument settings. According to the tutorial, it is done simply by pressing the REGISTRATION button and then SAVE AS--. Whether it saves volume setting is something I would like to know. The tutorial mentions saving slider position, but I assume it would be the knobs on the SD40, as the pictures don't show any sliders I can see.

You, like everyone, has their own ways of doing things, but I would be open to taking advantage of the great touch screen for some of your work, as it seems you could do it faster and easier that programming everything on a controller. But, that's just me.
