How to extract MIDI drum track from drum MP3

[Skyline_UK]

I have (from YT*) the isolated drum track from Hall & Oates' 'Maneater'.  I want to extract a MIDI file for it and see how the element of swing is done.  I've tried AudioSnap (which in all the years I've never really understood or figured out how to use...) and dragging the MP3 track to a MIDI track to see what Melodyne makes of it, which is not a lot because it doesn't know how to tell the difference between the kick, snare and hihat sounds.   And there is a tiny, tiny bit of (tape?) bleed on the drum track from some of the other instruments.  Is what I'm trying to do possible?  If so, how best to approach it?

I have not tried this personally but I would think that Melodyne would be your best bet. You could try to copy the file to several tracks and then filter them to try to isolate each peiece a bit more. It probably won't be perfect but might get you somewhat close.  

Cymbals are going to be the hardest I would think.

Try drum replacer for kick and snare

Many thanks all!  I'll give those suggestions a run out tomorrow.

Strangely I just made a tutorial on how to do something like this. There's no magic button. It's a lot of work. And the Melodyne tempo extraction can go haywire on you. I just did this again a few days ago on another old recording of mine and I'm rebuilding that song as well.

There's also this one on Drum replacer. Drum replacer was designed to be used on solo drum tracks from a multitrack recording and works badly on a mixed track.

But there's a much easier way to do this. I just Googled  "Maneater Midi file" 

Freemidi org is an easy to use site with 1,000's of good files and safe downloads.

I just double clicked the file and it opened in Cakewalk and played sounding actually pretty good with the TTS-1. Just make sure you have no midi outputs checked for that to work.

The drum track seems accurate to the original, nothing fancy. Interecting use of the Nylon Guitar as a bass! Never thought of that it actually sounds better than any of the GM bass sounds.

Many thanks John, I'll study that video.

I downloaded MIDI files and they all have the 'correct' drum part, but somehow that YT actual isolated part has a certain tiny 'skip' swing which I can't quite put my finger on.  As Lord Tim said, the kick is imparting a groove; certain push or pull to the pattern.  It's a very smart piece of drumming.

No humans were used on the original drum part. It says it was a Linn LM 1. It’s the bass line that to me gives  it that groove  The bass part was a direct rip of Supremes You can’t hurry Love  whom I believe might have been played by James Jameson  

Hal and Oats were among the early sequencer driven music groups that came out in the 80’s

Decoda  is able to separate out notes in a melodyne- like display and you can highlight notes you want to export as midi and then export those as midi. I have decoda but have never used it to export parts as midi so no idea how accurate it would be, but while listening to selected areas playing back it seems to separate things well.

26 minutes ago, Lord Tim said:

That said, I started with a Roland MC-500 sequencer and various slaved synths and drum machines, and the MIDI jitter was ridiculous sometimes!

Exactly what I was thinking. Things were definatly different back then.  My Roland 505 tempo drifts because that is set with a knob. It's gotten worse over time as a result of the pot is probably worn out.  I do remember that the Lynn drums were concidered the state of the art at the time.

This is listed on Reverb for $10,000!   It doesn't have MIDI but it did use a DIN jack for syncing( to what?? an Atari? ) .

This statment might explain the timing--   "This machine is legendary for a reason. Unbelievable sounds, the pitch function is phenomenal, the quantizing (for a super old unit) is surprisingly good. If you can find it, buy it."

a lot of early sequencers used precision (0.5% tolerance) thermisters (thermal resisters) and capacitor type "clocking" on some form of crystal master clock. the slow degrading of these devices eventually overcome any thermal stability afforded by the high tolerance components... so over time the stability and relative settings drift... i just fixed 4 synths and machines last year by replacing these components to get them mainly back in order...

[Glenn Stanton]

my Sequential Circuits Pro One was the rock-solid clock source for the rest of the devices (keyboards, drum machines etc) so one dial to turn for tempo ?

Have you guys tried Samplab? It's an audio to midi converter that seems to work pretty well with drum loops too.
There is both an online and a desktop version of the software. There is a fully functional free version, but the paid version can handle longer files. You should try this one.

Superior Drummer 3 has a way of extracting the different parts from audio as well .  Not perfect, but a good start.

After loading the Original version in and tempo matching, then loading a kit up and playing the beat in,  I found that the kick would line up when Eighth Notes were swung to 66% which is a perfect swing. ( just like a quarter note  and eighth note in 6/8 or 12/8).  The live bass moves around more so and adds to the feel as well. He’s over swinging the bass a little on the ‘And’ of 2 of every other bar where he’s by himself.  (Technically the ‘Uh’ of 2 And Uh)
