Three steps

Open the song in Stem separation and pick the 6-stem model (it splits out guitar and piano too).
In the Library mixer, press M on your instrument to mute it. Or press S (solo) to hear only your part.
Practice with loop, metronome and key/speed change — or click Save to export the backing track.

Slow the song down without changing pitch, or shift the key to match your tuning.

Loop the hard bar with A–B points and turn on the metronome and count-in.

Get a draft TAB from the separated bass line (beta).

Record your take over the backing track in the studio and mix it.

Which instruments can I remove?

Vocals, drums, bass, guitar, piano and other. Turn any combination on or off.

Does slowing down change the pitch?

No. Speed and key are adjusted separately.

Can I use the backing track on my phone?

Yes — export WAV or MP3 and copy it over. There is also an Android version of underdaw.

Does it cost anything?

No. Every feature is free, with no watermark.
