The woodshed for bass

nøta (from Swedish nöta): to go over something again and again until it sticks.

Nøta takes the songs you want to learn and splits each one into the bass on its own and a backing track without bass. Loop the hard parts, slow them down, read the notes, and play along.

Three ways to hear a song

Only the bass, taken out of the mix, so you can hear every note.

Notes view: The bass line as a piano roll with note names, read from the separated bass.
Loops and slow-down: Ctrl-drag a loop over the hard part and slow it down to 25% without changing the pitch.
Key and tuning: Move a song up or down in semitones, or tune it to match your bass.
Beat grid and click: Beats are found for you, tempo changes included, with a click and a count-in.
Your own sound: Play through your VST3 and Audio Unit effects, with a tuner built in.
Takes: Record yourself playing along and see your notes drawn over the song’s.
