Hi Rick,
You should find the answer to most of your queries in the above replies.

As far as split point goes, the R3 point gets saved with the voice in registrations and Style & Left points get saved with the Style. So if you have saved registrations with both Voice & Style ticked those regs should reinstate whatever split point you had at that time.
Unless:
- You have the Freeze button on affecting voice and/or Style

Or:
- Split point has been globally disabled.
Go to Function/Utility/ and scroll down to Parameter Lock.
Make sure there's no tick in Split Point.

John
