sure, that's a way, but if you do that you'll just have to set it up again every time you load a file, unless you play around with the current panel load options, but if you do that then you will have to hit a panel memory or change to another variation and back again to get the correct starting registration etc before you start to play a chord. But the advantage is using the fills to change the registrations. Going back to the 2nd selection is for presets and customs, not composers, but customs are not applicable to the 2600 anyway.
