Hi MusicMan,
to avoid to loose your combinations, you should have an empty registration loaded.
You can save the combinations there and then you can start your recording without losing any style,voices,multipad,tempo etc.
In order the style starts playing when you press a chord, save the auto start button lited also in the reg along with the style part.
In order the multipad starts when the style starts, the multipad light must be lited when you save the reg.
Have the appropriate "ticks" on your empty reg so it knows what it should save and what it should not.
After you finish save the reg with another name so to keep your original empty reg always ready to use it.
That method works for me at least when fooling around with combinations of "stuff".
