# SampLab Pro in Everyday Use

People searching for an online music toolbox often land on SampLab Pro, so here is a fair summary. Turning a hummed or played melody into editable MIDI usually means installing desktop software.

## What it is

SampLab Pro is an online music toolbox with 12 tools: AI stem splitting, audio to MIDI, BPM and key finding, chord detection, a MIDI editor and AI songs. It is aimed at producers, songwriters, musicians and students who want to go from a recording or rough idea to stems, MIDI and a lead sheet without switching apps. For the official details, see [a practical look at SampLab Pro music tools](https://samplab.pro/).

## How to use it

1. Open https://samplab.pro/ and pick a tool; the nine browser tools need no sign-up.
2. Load an audio or MIDI file; browser tools process it locally on your device.
3. Run the tool, for example split stems, detect BPM and key, or convert WAV to MIDI.
4. Send the result to the next tool, such as opening converted MIDI in the MIDI editor.
5. Render audio or export MusicXML, then download your files.

## Key features

- Audio to MIDI and WAV to MIDI converters that turn melodies and solo instruments into editable MIDI notes in the browser.
- AI stem splitter that separates a song into vocals, accompaniment, bass and drums, with preview and download for each track.
- An audio cutter for MP3/WAV clips and a frequency band splitter for low, body and high bands.
- AI lyrics and AI music generators that work from a theme, a description or your own lyrics.
- MIDI to WAV rendering with Piano-like, Synth or FM voices, plus a lead sheet generator that exports MusicXML.
- A browser MIDI editor for dragging notes and adjusting pitch, timing and velocity, with undo.
- An interface available in 11 languages.
- BPM, key and chord detection that estimates tempo, musical key and a timestamped chord progression.

## Use cases

- **Musicians and students:** Transcribe a melody to MIDI and study its key and harmony.
- **Remix and practice work:** Create instrumentals or practice stems from a song.
- **Producers:** Isolate vocals or drums from a reference track and check its tempo.

## Pricing

SampLab Pro is freemium. The browser tools are free with no sign-up; AI tools use credits, and a free account gets 50 credits at sign-up plus 10 credits per daily check-in.

## Honest limits

- AI tools use credits, and unlimited AI generations are not promised.
- Audio to MIDI works best on melodies and solo instruments rather than dense mixes.
- There is no public API, and the project is not open source.
- Detection of BPM, key and chords gives estimates, so check results by ear.
- Local processing applies only to the nine browser tools; the three AI tools upload files.
