A finished song is one audio file with every instrument mixed together. To learn the bass line, or the piano part, you'd normally have to pick it out by ear.
MIDI.PLAY can pull the song apart into separate tracks, one per instrument. Musicians call these isolated tracks stems.
How it works
- Add a song from YouTube or an audio file.
- When asked, choose to split it into instruments. This takes a few minutes; the screen says roughly how long.
- Pick the instrument you want to learn. Its notes become the falling notes.
- Practise. The other instruments play from the real recording, so it feels like playing with the band.
You can turn each instrument up, down or off in the mixer while you play.
Why split at all?
Two reasons. The notes come out cleaner when the app only has to listen to one instrument. And you get a real backing track instead of playing alone.
If you're in a hurry you can skip the split. The notes are worked out from the whole mix instead, which is faster.
