Hey thanks for the quick responses...........
Problem is the times this occurs is when I may not be using a style and with the OTS enabled I can't get rid of the style easily to get back to what I had. Yes, setting a 'Registration' at least gets me out of OTS, but not necessarily back to a voicing setup I previously had which may be splits or layers that I might not normally save as a registration while I'm playing around looking for a particular sound.
