BeatStack サウンドミックス

Layer sounds and get a DJ mix. 92 built-in loops that all share one key and tempo. Import your own songs or record with the mic. Japanese interface only.

Note: the app interface is currently available in Japanese only.

BeatStack lets you make a DJ mix just by layering sounds.

Pick from 92 built-in loops and arrange them. Every sound shares the same key and tempo, so anything you stack together works musically. No instrument skills or music theory required.

• One tap to a full track Choose your sounds and they are arranged into an 8-bar structure automatically, with beat, percussion, bass, chords and melody already placed.

• Overlap is the crossfade Drag clips so they overlap, and the overlapping length becomes the crossfade. There are no fade settings to learn.

• Use your own audio Import songs from the Files app, or record with the microphone. Imported and recorded audio stays on your device and is never uploaded.

• Generate sounds on the spot Create melody, chord, bass and drum parts on the fly. Reopen a project and the same sounds come back.

• Projects stay editable What gets saved is a recipe, not an audio file. Swap sounds or change the tempo later without starting over.

• Playlists Line up your tracks and play them back to back.

Everything works offline.

[Premium] A one-time purchase (500 JPY) lets you export your track as an audio file and share it. No monthly payments.
