You can turn any existing tuplet notes into normal notes; for example, if you want to turn tuplet eighth notes into standard eighth notes.
Procedure
Result
The selected tuplets are deleted. All notes previously in the tuplets are unscaled and appear as normal notes with the same notated duration; for example, a tuplet quarter note becomes a standard quarter note.
When Insert mode is activated, all notes in the tuplets are retained and any subsequent existing notes are pushed to later rhythmic positions to accommodate the extra rhythmic durations required. When Insert mode is deactivated, the earliest selected tuplets expand and overwrite subsequent notes and tuplets.
