shifting notes rightwards using SHIFT right arrow

Howdy John,

In the Piano Roll tab there are three buttons that determine how edits are handled.
If the first one is "on", then both performance and notation get edited.
If the second is on, only notation is edited and
if the third is on, only performance is edited.

You want the first button "on". (You can mouse-over them for the tips.)

ttfn,
Sherry
