Features
The data the crate
never came with.
Drop it into your session. It listens. You keep digging.
Key & BPM detection
Identifies the musical key using the Albrecht-Shanahan tonal-profile method, with a genre-aware tempo prior tuned for slow soul, funk and jazz. Every result carries a confidence readout, shown in standard notation and Camelot code.
Live monitoring
Start Live detects key and tempo continuously from any input as audio plays. On Mac, capture system audio directly — analyse a track from your browser or DAW with no routing cables.
Record, drop & analyse
Capture from any input, or drag-and-drop an audio file to analyse it. Play it back on a scrubbable waveform, tap tempo by hand, and review the key/BPM of every session.
Harmonic compatibility
Camelot-wheel mapping plus Perfect / Workable / Avoid ratings tell you instantly whether two samples fit. A harmonic map lays out your library by key relationship.
Private sample library
Scan multiple folders into a private, encrypted library. Files are hash-keyed so metadata survives renaming or moving — and your files are never renamed or tagged. Search by key or BPM.
MIDI & export
Transcribe the detected notes of a sample to a MIDI file, and export your audio as WAV or MIDI.
The Crate
Your whole library,
scored against your track.
Set the key and tempo you're working in. Riftly flips through everything you've scanned and rates how well each sample will actually sit under your beat — then tells you exactly how to make it fit.
Hear it in place
Click-free 10-second previews straight from the crate — flip through records without breaking your session.
Told how to make it fit
Every sample comes with the pitch and tempo move to align it — not just a number to interpret yourself.
Into your session
Send it to the sampler, or reveal the original file on disk and drag it straight into your DAW.
What producers say
Early feedback.
This is absolutely amazing. I know so many people would definitely be interested in this once it's live. Really impressive work — I appreciate you building this and letting me try it.
Beta tester
Melbourne producer
Honestly, this is one of the better key finders I've seen. It's usually within a note or two. The sampler is great, everything checks out. I can see a lot of people enjoying this.
