This service allows you to analyze MIDI files.
I've created it in a few evenings to count the number of notes in Black MIDI files that usually have a tenth of thousands of notes. And only after the project was finished, I've realized that some Black MIDI files may be in terabytes of size. But my server can handle only up to 8Mb file size. But hey, I've got what I've needed. So I leave it online. Maybe it'll become useful for someone else.
I've also added some other statistics. Like MIDI file notes range, time signature, tempo and tracks information. Service displays it if possible.
If you have any thoughts you'd like to share, found any bugs or would like to see any additional features, feel free to contact me at firstname.lastname@example.org.Let's Get Started!
