How playing and scoring work
Input & scoring settings
Tap Space (or the button) on every bass note you hear.
What each setting does.
Plug your bass into an audio interface for best results. A microphone in front of the speakers will also hear the song's bass and score it as yours, so use headphones or pick "Bass removed".
