Tune recognition

Play a tune, it finds it

The recognition engine has been rebuilt: each tune's key signature is honoured, the melody is followed even with accompaniment, hornpipes and swing are tolerated. Right answer on top in 64% of tested clips (40% before), an answer in under a second — and an honest verdict: green only when it's sure.

Your tunes on every device

Repertoire, sets, tags and settings follow you from phone to tablet to PC. End-to-end encrypted: the server never sees your data in the clear, and one pairing code is all it takes to add a device. Premium feature.

Studio (beta)

Record yourself, arrange your sets

A reel then a jig in the same project, each at its own tempo and meter. The accompaniment swings with the melody, the bodhrán phrases, piano, accordion and harp answer. Each take is realigned by ear right after recording; M4A and MIDI export, project sharing with the community.
