I'm a drummer and I don't play neither guitar nor the piano. I got an mp3 where there is only an acoustic guitar that plays chords. There is a software (or something else) that recognize the chords in mp3 file and play those chords with a piano sound (with a VST probably)?

thanks!

  • If you happen to have access, I believe that Melodyne can do polyphonic audio to midi, at which point you can just feed it to any piano vst

  • Melodyne won't "recognize chords" as @Insoft requested, it will just reproduce the exact notes it hears. And if the mp3 file has anything but one solo guitar with relatively few effects, it won't work very well. Apr 4, 2017 at 9:55
  • @prooffreader : my impression was that that was what the OP was actually looking for, but you're absolutely right -- melody he will be an exact, note-for-note reproduction, not a new piano arrangement.

What you're describing is a multistep process.

1) First is chord recognition. This is hard to do, but artificial intelligence is making it easier. That said, the only software I'm aware of for a non-programmer to use that also works pretty well is Chordata: here's the download link, but be careful, like all download sites it tries to get you to download crap along with it. Click the button that says 'trusted download', and then on the next page Answer 'no' to the popup that asks you whether you want to download a 'helpful download manager'. When you run the installer, I can't remember if it tries to get you to install other stuff too, just pay attention and opt out. Unfortunately, that's the state of software today.

Chordata won't save the chords for you, unfortunately, you'll have to write them down. This is a feature, not a bug, because like all automatic processes there will be a few errors you'll want to weed out by ear.

2) As for then playing those chords, there are a few VST that can do that. Chordz is free, but you'll have to record the basics of the midi track. Key chords is $15, but it allows you to just name the chords and it will play then, plus there's even an iPad app.

I'm sure other solutions exist for the separate parts, but I've not yet heard of anything that automates the whole process.
