Cerno pilot access
Cerno is in private development. Discuss a guided pilot for a real reference task. An enquiry does not create an account or guarantee availability. Scope, any price and timing are agreed individually.
The workflow
In a guided session, we operate Cerno with you and review the track from the top down: tempo, key and meter, the song map, then the available musical parts. The evidence panel provides more detail where you need it.
Supported audio
WAV, AIFF, FLAC, MP3 and M4A. Use audio you are entitled to upload. A lossless source is preferable; lossy audio can make analysis less reliable.
Checking tempo and notes
Tempo can be ambiguous at half or double speed. Cerno shows alternative readings where available, but a confidence score is not a guarantee. Section boundaries, chords, bass and melody need listening checks. Some results may be absent when an analysis cannot support them.
Stems
Available separation depends on the analysis configuration. The pilot scope will identify which outputs can be provided. Four-stem separation is not a promised pilot deliverable.
Blueprint MIDI
The export can include a tempo map, section markers, chords, bass, melody and a drum guide, depending on the analysis. It is a starting point to review, not a complete or guaranteed transcription. Marker and tempo import behaviour differs between DAWs; we check your own workflow during the pilot. The drum guide describes onsets, not classified drum hits.
