Hi here 
!
I have a full 4/4 score of triplets and I would like to convert them as quavers in a new 12/8 score (after pasting them). Is there a way to to achieve that without re-inserting all the notes one by one as quavers? I have tried to play with “requantize” but that doesn’t seem to be the right tool to achieve that.
NB: I’m not an expert in music theory, I just know the basics.
I’d say you can use the insert mode, filter and delete all tuplets, and apply a new time signature. You might need to lengthen some quarter notes (into dotted quarter notes). Honestly, that’s all I can tell you without seeing the score.
Press i, select all, filter the tuplets, delete. Done.
Wow! Thank you so much!
The new insert modes scopes gives even more options when the score is getting way more complicated to deal with tuplets. You’ll see when you need it

Great piece of information, congrats!
Yes I tried to find it in the documentation for a while but I admit I didn’t really know what keywords to use to find it. Thank you!
If in doubt, just search using terms you’d use to phrase the question here. I try to make sure common synonyms and mannerisms will return relevant results.
Understood

Of course, if you ever find yourself unable to find something based on sensible search terms, please do let me know! There’s always going to be corners that could be improved.
