Writing to Flash Memory always takes a bit longer than reading from the memory - it's a function of the technology. However, you've found the basic solution to your problem Ray - only save the parts you really need, on Page 2/3. Not only will this result in shorter 'Save' times, but songs or set-ups saved this way will also load faster.

Incidentally, when playing at a gig, and you want to save that little bit extra time when loading the next setup or song from the SD card, try the following:

While you are still playing the current song, at suitable spaces in either left or right hand playing, press the SD Load button, then the 'Load' button and navigate to your next song in the list. Then when you have finished playing the current song, just press the 'Load' button and your next song or set-up, will be loaded, resulting in less 'down-time' between songs.
