Modifying 3 consecutive eights into a triplet - How?

I have 3 consecutive eights and I wish to turn the into a triplet without re-typing them all over again.
Is there a way to achieve that?

Thanks.

Hillel.

In Musescore it is not. Maybe someone had a good idea and wrote a plugin. But:
Any automatic change would have the problem that the measure length is no longer correct. A triplet with three eighth notes takes only the place of a quarter note. Should there now be an eighth note rest or should the other notes move one eighth note to the left? Also those of the following measure?

> How?
Delete them, create the triplet and write them again ...

Well - I have too many of them.
Delete / rewrite is merely impractical.
It would mean a rewrite of the piece as a whole (or at least - the most of it).
.
There must be another way.
"Duration editor" was mentioned above.
I'll try to figure out how about that...
Thanks.

Changing 3 regular 1/8 notes into a triplet also modify the measure content length.
So either the measure will become too short or it is too long to start with.
So I'm curious, when you say you have too many of them, how is the score now?
Can you post it and explain how you'd like to change it?

The attached PDF was downloaded from the WEB.
It contains a piano arrangment of the well-known Bach's "Toccata and Fugue BWV 565".
I use "ScanScore" as an Optical Music Recognition (=OMR) tool.
It did a good job in producing an MXL file, which was later loaded into Musescore.
Notes seem to be recognized fine.
Yet - ALL occurrences of triplets were recognized a consecutive sequence of eights.
For example - look at the MSCZ file for the 1st occurrence, at Measure #3.
Measures are expanded respectively.
I am looking for a way to modify all these patterns collectively, instead of fixing each and every individual occurrence by Delete/Rewrite.

Thanks.

The problem in your score is that the triplets are assumed to be known after being marked once. No automatic conversion can detect this.
I loaded your PDF into my local installed Audiveris (which is also used musescore.com). There it is a bit easier to add the missing triplet 3s and then transfer them to MuseScore. But it is still some work to be done.
Added a little exercise from me as attachment.

Thanks a lot.
Well - processing it with Audiveris made the differnce and produced better results.
I also have Audiveris installed locally on my Laptop, but my experience with Audiveris was not very good.
Hence, I purchased ScanScore.
It manages to achieve reasonable results even when processing rather old photocopies, having bad clarity and very low visual resolution.
I suspect that ScanScore optical recognition failure stems from the fact that the "3" figure - indicating the triplet - is "small".
In addition to that - it is placed underneath the beam while above there are "confusing" figures that indicate fingering.
But this is not an excuse...
I will give Audiveris another chance.

That way or another
Thank you for your help.

Not only the small triplet numbers are a problem, in the measures after measure 7 there is no number at all. How is an OMR supposed to recognize this correctly, even if the triplet numbers were clearly written?

When you create a score by OMR, you either have to listen out every mistake or spend a lot of time comparing it to the original.

OMR is not perfect, unfortunately.

Sadly - you are absolutly correct.

>>> in the measures after measure 7 there is no number at all
Ok.
In my humble opinion - an "inteligent" OMR is not expected to expand the measure's time signature in this case.
One might expect that the recognized fixed time signature - which is known in advance - would conduct a logic that could interpret them as triplets.
Is it a wishful dreaming...?

>>> OMR is not perfect
That right.
But it is very beneficial for my work in rescuing and digitizing old archived material.

Thanks again.

I think so. But the biggest problem with OMR seems to me to be correctly recognizing and interpreting all the elements that are actually there!
Here it could be recognized by the beam grouping, because that is the only difference to the last two eighth notes in the measures. Otherwise: which of the eleven eighths are triplet members and which not? And what is, if there are quadruplets instead? Or other complex combinations?
Maybe in the future an AI will be able to do that.
