Live Bass Trainer for Your Audio Interface

Plug the bass into the instrument (Hi-Z) input of an audio interface and choose that interface as the input in your browser. Pitch is detected in the browser itself; the audio is never uploaded.

A note counts only when its exact pitch is played, and by default the octave must match too. The tolerance can be set to ±25, ±40 or ±50 cents. When the note is right but sharp or flat, the trainer tells you by how many cents so you can retune.

Open strings, chromatic drills, scales, arpeggios, octaves, note hunts, genre grooves from the riff library and Anatolian makam lines in aksak 9/8, in wait or tempo mode with automatic speed-up.

No. A string still ringing under the next pluck does not hide the new note, and touches more than 20 dB quieter than your recent plucks are ignored, so moving your hand is not scored as a mistake.

Yes, in two ways with different limits. Play-along mode loops a genre riff with drums and shows its notes and TAB while you follow on your own bass or just listen; it needs no microphone or interface, and nothing is scored. Demo mode sends the notes you tap on the on-screen neck through the same pitch detector, so you can see how scoring works. Note-by-note scoring of your real bass needs the interface.

Partly. Play-along minutes are logged apart from scored time and shown as played along, not scored. They stay out of the 60-minute daily hour, and up to 15 minutes a day count toward your practice streak. The log is kept in your browser.
