UNDERSTAND YOUR RESULTS
The six-part mode produces vocals, drums, bass, guitar, piano and an Other stem that groups the remaining sound. Scan suggestions help you choose parts; you can adjust the selection manually. For note recognition, start with a solo recording or a separated part. Drum recognition currently covers kick, snare and closed hi-hat. Review tempo and time signature before using or printing a score.
