Learn Bass Guitar with Any Song You Own

BassRack is a bass trainer built to run in your web browser. It is not open yet: join the waitlist to hear when it launches. You bring a song, BassRack’s AI isolates the bass, turns the bass line into a playable note highway with string and fret numbers, and scores your real bass, note by note, while you play along. It also has a Conservatory: schools of scales, groove, technique, arpeggios, walking bass and guided technique, with generated exercises.

The Free plan costs nothing: it includes every feature, the Conservatory (its lessons open in order as you clear them), the A–B loop, the chart editor and uploading your own files, with ads. Every plan also includes BassRack Amp, the free, optional companion program for your computer, which processes songs faster with your graphics card on Windows, imports songs from download links and records your computer’s audio. BassRack Pro removes the ads and opens any Conservatory lesson from the start. BassRack Studio does the same and adds processing on our servers for devices that are too weak. BassRack Pro costs $3.99 a month or $29.99 a year. BassRack Studio costs $9.99 a month or $79.99 a year and covers about 50 songs a month; your audio is deleted after processing. Prices are in US dollars and include VAT and sales taxes.

A set of schools for learning bass without a song: scales, groove, technique, arpeggios, walking bass and guided technique, each one an object you play (a method book, a drum machine, a pedalboard, an arp synth, a jazz club and VHS tapes with a TV). Every exercise is generated, so every expected note is exact, and every lesson comes with an animated explanation you can listen to. Scored lessons have levels, stars and points; guided technique (slap and pop, finger alternation, ghost notes) is not scored yet. On Free, lessons open in order as you clear them; BassRack Pro and BassRack Studio open any lesson from the start.

No. BassRack is built to run in your browser. BassRack Amp, the companion program for your computer, is free and optional: it makes processing faster and adds importing from a download link and recording your computer’s audio; uploading your own files never needs it, and no plan requires it.

The free companion program for your computer, optional and on any plan. On Windows, it processes songs faster with your graphics card (any graphics card with DirectX 12, from NVIDIA, AMD or Intel; otherwise the processor); on Mac, faster processing with the graphics card is not available yet. On both systems, it imports and records songs. A Windows beta (the Microsoft Store comes later) and a download for Mac (macOS 14 or later) are coming soon to the BassRack Amp page. It sits next to the clock or in the menu bar. When it runs, the tuner in BassRack raises its antenna: paste a direct download link to an audio file or an archive.org page, or record what your computer plays, or one app (one app needs Windows 11; on Mac, recording needs macOS 14.4 or later), at high quality and in real time. The song becomes a new cassette in your library, and the files stay on your device. BassRack doesn’t import from video sites or streaming services. Use only audio you own or have the right to use.

It talks only to the BassRack page in your browser on this computer, and to the download link or archive.org page you give it, and it never listens to the network. It is paired with your browser the first time you use it, so nothing else can use it. Nothing goes to BassRack’s servers: the songs it processes, imports or records stay on your computer.

Any electric bass and any audio interface with an instrument input, connected by cable. Four- and five-string basses are supported, in standard and drop tunings; charts are re-fingered instantly when you change the tuning. Pick the device and the input (1 or 2) in the Rig panel.

BassRack works with your computer’s microphone, but room noise and the music around you can confuse it. For clean, accurate note detection we recommend a bass/guitar cable with a 6.3 mm jack on one end and USB on the other: it usually shows up as an audio input on Windows and macOS, and on a phone or tablet you may need a USB-C adapter. A small USB audio interface with an instrument input (often labelled Hi-Z or Inst) is the step up. See jack-to-USB cables on Amazon ↗ (opens in a new tab)

Practicing needs a recent browser (Chromium-based or Firefox) with low-latency audio and an audio input. Processing songs on your own device, which comes at launch, will need a capable graphics card with WebGPU; on weaker computers, phones and tablets you will still be able to practice everything, and BassRack Studio will process the songs on our servers.

BassRack is designed so it does not. On the Free and BassRack Pro plans, your library, your songs, the separated tracks and your playing will be processed and stored on your own device. With BassRack Studio, only the files you upload for processing will be sent to our servers, and the audio is deleted after processing.

A tab tells you which frets to play, but not exactly when, and it cannot hear you. BassRack shows every note in time with the real recording, listens to your bass and scores your timing and pitch, lets you slow down without changing pitch and loop any passage. If you have a tab you trust, paste it: BassRack aligns it to the song.

Music you own or have the rights to use. Upload the audio file you have, or import it from a download link or record it with BassRack Amp, the free companion program, under the same rule: use only audio you own or have the right to use.

Results depend on the recording. Clear, well-mixed bass lines work best. Techniques such as slap, ghost notes or chords may need a manual check, and you can review and edit any note in the chart editor.

Not if you use direct monitoring on your audio interface: you hear your bass straight from the interface, with zero latency. Software monitoring is optional and adds a small delay. Run the latency calibration once per setup so scoring stays fair, and avoid Bluetooth headphones.

No. The highway shows the string and fret of every note as it comes, and you can add note names. Start on Easy and move up when you are ready.
