BSharp:

Do this:

Create 8 of your favorite voices and save this as a registration.

Put a label above the buttons so you know which voice is which.

Now call up this registration and expand on it by associating a style, tempo, transpose, etc with each voice. Make names for each button with the name function. Rename the registration.

When you're done with these eight, create another set of eight.

Now all you have to do is

1. Call up the registration of your choice
2. Press Freeze (locking the style, tempo, and transpose,etc.)
3. Press the OTS or the registration button of your choice to call up your preferred right voice.

Now you have the 4 OTSs plus eight of your favorite voices.

Ready for the next song?

1. Press Freeze to undo the freeze
2. Call up the registration
3. Press Freeze again

I think this is pretty simple.
