Track Roller?

Like a long sheet of paper looped around two toilet paper rolls, i would like to be able to roll tracks. So if I press insert, optionally, it would be nice to have the bottom notes not disappear but rather wrap around back at the top.


Would be very useful especially to fix live recording that started one beat to late or things like that.

I have some suggestions of how it could be done in a very versitile way from advanced edit.
