I've been looking around for something to do this and all i have found was python algorithms, which is fine, i was just looking to see if anyone has heard or seen something capable of a bulk detection.

thanks homies

 

I've never heard of software that detects the key of a multiple MIDI files, let alone one. It's a first for me. I'm curious as to how accurate such programs are, especially when it comes to songs with modulations/key changes. I wonder how well it handles songs with accidentals...

 

Should be able to be dead accurate when you consider... All the information is in the file and readable as a pose to something that needs a detection algorithm. I would love to see something like this available!

 

Getting python to iterate through a list of files should be a piece of cake. Mind giving us the url?

 

Honestly, this is the very basic of music making. You're not helping yourself by trying to make it easy.

My advice is simple: study! If you love music, honor it. You'll have much more fun and possibilities by doing so.

 

The best software ever : Your brain !

 

Not to be rude, but do you actually compose music, or do you just remix others' music/work with pre-existing MIDI files? Either way, learning the key of a piece of music is pretty rudimentary stuff -- you don't really even have to know how to read music (I can't) in order to figure out what key it's in. Actually learning the basics of music theory will help you a hell of a lot more than any piece of software.

 

Why is everyone trying to tell him to learn doing it on his own? Maybe I missed something, but he didn't write what he was going to achieve with his detection. Maybe he has like 1000 files that need to be categorized?
Anyway, a little bit of more information would be nice...

 

Mix in key software might do it I don't know if it works with Midi files i use it with audio files try it

 

I appreciate everyone's advice and insults. It was just to organize everything, i have like 450,000 .midi files that I would have liked to get into order, most of which were made in my studio. Its just that when you're riffing and you are really feeling what you're doing, you sometimes just want to save the file and move onto the next task. It's not that we're lazy, uneducated, or even slackers. We just have a lot going on and sometimes we don't have the kind of time to sort out every single key.

Therefore, i was looking for an easier way to get everything into order instead of opening every single file one by one and keying them out.

When did everyone get so hostile ?

 

Here's the link i found. Unfortunately i couldn't get it to work and it's for individual files.

Band in the Box can detect chords and then it maybe easier to figure out the song's key. Capo does it for audio files. But in both cases you gotta figure out the key from the chords displayed.

EDIT:
I just saw you gotta sort 450,000 files. Man, that's loco. I don't know any tool that will batch detect the key of midi files.

Try this :D

Batch?????? On second thoughts, no it wont do it in batches. Sorry I didn't see the 450,000 midi files when I posted this.

Sheesh 450,000


UPDATE.. It will queue them so it kinda does batches but approx 10 mins each track, you may be older than yoda by the time it finishes all of em.

Remember midi is data that can refer to a variety of thing and is not music. Also there are different types of midi files so you could have a big job on your hands. Typically, 3 types of midi file, typically Key data will be included in midi metadata if it there with references how many intervals from C and whether major or minor.
U could use a hex editor or something else to determine key and other data quite easily but it could take u a while to do 450,000 files
Not sure of bulk on mass type programs

 

Thanks man I'll try it out tonight

 

Haha yeah it's quite a large bank. We usually just mess around on the boards and save the midi file but not really in terms of key just in terms of what instrument we played that midi file on.

 

Thank you to anyone who was kind enough to try ! It's really appreciated.

 

Ok here is a gold mine tip just remember to send me sexyman lots of money when you make it big in the music and get rich.
I use toontrack ezkeys to see what notes and chords are played in a midi file. just import the midi file or drag and drop the file to ezkeys time line. and select no to converting the file to key that ezkey is set to.
also the midi file should have only one track so if you Dl a midi song file use a daw to delete all other tracks and leave the track that has the keys you want to know.
I also use riff station to find song keys and chords from mp3 files.

Yep good bit of info there have fun recycling old music thats the way to go.

My only 'cheat' is performance related and I transpose my keyboard so the tonic is always on the C note (major scales) and A note (minor scales). This helps me to concentrate on the scale degrees (hint: you mostly play the white keys), as I am not really a keyboard player. It makes playing chords, variations and inversions a breeze as they are always in the same position no matter what the key is.

Sorry if it's slightly off-topic but it might be helpful to some
