Anyway to convert a mp3 melody to midi or way to find out the key/scale used?

Hello,

I hear a lot of nice melodies and can never train my ear to find what chord,key or scale they use, it doesn’t help I have a slight loss of hearing in 1 ear too. Is there an application I can use to convert an mp3 of a melody I have heard and convert to midi or just expose what chord, key, scale used? I did locate a site called moises.ai.

My son came over the other day and said listen to this nice tune (he means melody) and I really wanted to show him it can be done on my Keystep (via my Digitone2).

Thanks

Thanks, what version would cover this do you think?

I have the SE version (vst) but I believe there’s a version that listens to all audio running through your system (think it’s called live version maybe?)

Edit: it will highlight the key and the notes used, but if you want to go note by note you want to have the ability to loop a note and then go one by one like that, otherwise it’ll display all the notes it hears

What you can also try:
Ableton Live can do audio to midi, but you’ll have to clean the midi up quite a bit when you use it on a full track as it will also do all the percussion. It can work, but usually it’s just confusing me more.
If your DAW doesn’t have such a feature, you could also try to slice it into 16ths (or 32ths if needed) and then just trigger one slice repeatedly and look where the peaks are on a spectrum analyser. Have a simple triangle wave or piano sound ready to compare the notes you found with. With a bit of practise, you’ll be able to find the correct notes or chords within a seconds of listening to each slice.

Put the notes into this tool Scale Finder

Edit, probably overkill if you only want to find out which key a track is in, but maybe you also want to find out which notes were used.

Yeah that live version looks very useful, I’ll check it out. At least it might get me close to what I need. I’m mostly DAWless tbh, but imagine there is a way to export some to a midi file to import on a sequencer, that would be amazing if possible.

For MIDI you need a different tool, MIK will only do analysis. You got to put in the work yourself or find another tool. Scaler 3 can analyse and output midi files, but I think you’d need to split the stems and import into it a section where only the melody is present. There’s no easy way to go about it.

I used to use software called Transcribe! to … transcribe music. It was useful. This seems like an area AI where could really shine.

There are a bunch of free online tools where you can upload a song and it will tell you the bpm and key. Always confirm the accuracy for yourself after you’re in the right neighborhood though.

For now, maybe we can help you with that particular song if you wanna share it :wink:

studio.moises.ai split the stems out which is good

Melodyne may have a demo, or at least there seem to be lower cost licenses.

Some of these are pretty useful, but I notice they can have trouble distinguishing major & minor keys, at least in the music I listen to. They also transcribe up or down a fifth sometimes. But yeah it’s way faster than trying to do it all by ear from scratch.

It’s 2025, there are easy ways to do everything. Except for root canals, those are still very difficult.

I’d wager my suggestion is already extremely easy in itself. Easier would mean, in this case, to not require any work whatsoever, and, as far as I know, that’s not available on a reliable manner.

Apologies for my music tastes:
Song 1
Song 2 (love the lead, that’s the part I want)

The ideas is to be able to play these on my Keystep or Sequence something similar on my Hapax.

That one seems in G major.

That one seems in F aeolien / G# ionian.
Chords are Fm / G# / Cm / C#

We all have our dirty secrets :wink:

My dirty secrets are all out in the open now though :smiley:

Can I ask what your techniques were to get these? Interesting Song2 uses 2 difference scales. I’d like to try some similar melodies, but can never get a similar tone (scale, key, colour), Song 1 sounds sad, song 2 happy and uplifting.

lol since when did Houseum become dirty? It’s very cool in my book

I know there are no rules in music, but to me Song2 melodic and harmonic choices sound very questionable. At different points in the song the clashing is so evident and annoying that I find it hard to believe is by choice.
