Stop digging—start creating
CoSo listens to your track in real-time, then serves up Complementary Sounds that go together. With the "does this sound good together" out of the process, you can focus on letting your creative instincts lead you.
Instinctual creativity
Create a Stack by choosing a style then add up to eight instrumental layers from across the Splice catalog—every selection is uniquely yours and destined to work.
Everything under your thumb
Swipe right to choose a new sound, swipe left to delete, tap a layer to mute it, and long-press to solo. CoSo’s here to create musical momentum.
Save. Send. Share.
Send your stack to TikTok, save to your library, share with a friend, or export it to Ableton Live (coming soon). You can also locate your sounds in the Splice library to use them in your DAW.
