Hi John,
Fairly straight forward

1. Having created your set-up for a particular song/tune, which does not use the sequencer, press Program Menus > Control > Initial.
2. Scroll down the 'INITIAL' screen until you highlight 'Sequencer'.
3. Press OK > YES - This will clear the sequencer but leave all your other settings intact.
4. Now just save your song/tune as normal, but on Page 2 of the save screen, make sure that the Sequencer option is set to 'YES'.

That's it !!
If you do this as a normal routine, then the 'unexpected' sequencer appearance, will not bother you again.
If you are certain that there is no data in the sequencer when you create your song/tune, then you can skip steps 1 to 3.
