Questions

Can I loop a section?

Yes. Press Loop from here at the start of the section and to here at its end. It repeats until you stop looping.

How slow can it go?

Down to half speed, without changing the key.

How accurate is it?

Major and minor chords in pop, rock and folk songs come out well. Jazz chords and busy mixes are simplified to their main triad.

Is it free?

Yes, to try. Without an account you hear the first minute of any file and can download it as an MP3. A plan does whole files and downloads them in studio quality, from US$6 a month, with the first month at US$1 for new customers.

MP3, WAV, M4A, FLAC, OGG, MP4, MOV and WebM all work, depending on your browser. Songs can be up to 20 minutes. Each stem downloads as a 24-bit WAV, the mix as you set it as one WAV, or all six stems at once as a ZIP.

Does it work on my phone?

Yes. It works in the browser on iPhone, Android, Mac and Windows, with nothing to install.
