So you are a composer, right?

You have written hundreds of scores for movies, documentaries, series, albums and singles.

But, you did all of that, a long time ago, way before computers were around, right?

Remember those Bach scores you had to learn while at music school?

Do you remember how many pages those had? Papers and papers everywhere!

And now, you are looking for a way to “digitize” all of those old school papers into the computer.

Is there a way to do that?

Can you somehow convert those old and rusty score papers into digital files that your computer can easily read?

Is there a way to “scan” them?

Guess what?

There is! It is called Optical Music Recognition!

And in this article we will review the 6 best PDF to MIDI converters using optical music recognition.

What is Optical Music Recognition?

Optical Music Recognition, also called “OMR” is actually a field of research that studies how to use computers to read music notation scores and transfer them into a digital file readable by the machine.

Engineers have developed software that lets you import (or upload) a PDF of a score, let’s say a score you have printed or even written.

Once this has been imported, the software will “read” the notes and their associated durations and “convert” the information into a digital file that can be read by the computer.

These digital files can be MIDI, which is the most famous music type file, as well as MusicXML.

Once these scores have been converted into MIDI, you can actually load these into your favorite DAW or sequencer.

When you load the MIDI files, you can associate your virtual instruments to each of the tracks and “playback” the material, just as if you had the orchestra right in front of you.
