Slow songs down, change the key, loop the bars that need work. Isolate instruments with AI,
follow lyrics and charts as the song plays, build and export setlists. All in one powerful app.
Full features for 14 days • No credit card • Interactive tutorials included
Stop practicing one section at a time. Build custom sequences, train
through keys, and learn songs faster.
Practice verse 2, the solo, and chorus 3 together, each with their own tempo and key. Add or remove sections on the fly as you master them.
Speed Training gradually increases tempo. Key Acrobat transposes through all 12 keys. Perfect for jazz standards and technique building.
Create unlimited regions visible on the waveform. Organize into groups. Every section saves automatically with your song.
Export a song with its regions, loops, lyrics and settings as a single file, and send it to a student or a bandmate. They import it and get your whole setup. Coming from Amazing Slow Downer? Your bookmarks import as regions.
Professional tools under the hood, designed for serious musicians
Follow synced lyrics, chords and notation as you practice,
then turn the same songs into a gig-ready setlist
Plan tonight's session across your whole library, and keep that library
in step on every computer you use
Queue songs from your library, give each one a time budget, and press start. The app loads each song in turn, counts it down, keeps your checklist in front of you, and shows you afterwards where the time really went. Save the plan and run it again tomorrow. A plain countdown timer is there too.
Songs, regions, loops, lyrics, chords, notes and setlists stay in step across your computers. Audio downloads on demand, so a new machine has your whole library right away. 500 MB of storage is free, Sync Plus adds 15 GB, and sync is optional: the app works fully without an account.
