The transcription

Record something and it will be written out here.

What it heard

Settings

Coarser is tidier; finer keeps more of what you actually played.
Fix anything it got wrong

Pitch detection is very good on a clear, sustained note and less good on consonants, slides and quiet endings. Nudge anything it misheard.

If it is not hearing you properly

What counts as a note

Raise this if breaths and consonants are being written down as notes.

Sing to a click, hold each note, and leave a small gap between repeated notes. That is worth more than any setting on this page.
