Is it possible to change a bar with eight rests and eights notes fast into tuplets? See example picture below (staff2 is the result).

Not really, I think. As far as I know, it’s not possible to put a tuplet over existing notes without deleting them.
The quickest way I could think of makes sense only when the pitches don’t change, as in your example.
- Activate note input and create the first triplet. This will overwrite the first eigth note.
- Select the second group (rest and note) and Alt-click on the second rest inside the triplet.
- Select the whole triplet group (including the triplet) and hit R repeatedly. This will repeat the selection, but overwrite anything else.

Hope this helps!
Edit: Come to think of it, my answer is just a complicated version of “write the first triplet and repeat it”…
Thanks for your answer. Your sample works but I think that’s not the way I will do this, then it is faster to write the first triplet and repeat it ![]()
I second that question. The quickest way I found is:
- select the first rest
- Press
;for the tuplet popover - Put
3:2e - Move the eighth by one

This is slightly more complicated if there are other notes after, but it’s still doable:

Though I feel like that should be easier… A “straight to swing” button could be extremely useful here. (because this is practically what is done here).
