Splice CoSo uses AI to help you quickly create music with samples

Splice, the popular music production service with a seemingly endless supply of samples, has just unveiled a new way to find inspiration from those sounds. CoSo is what it calls a “smart musical sketch pad” that lets you create “using your ear to find what appeals to you,” the company wrote in a press release.

CoSo lets you stack up to eight samples based on genre or instrument type to create loops quickly, with great AI help. Everything stays (more or less) in key and time, and you can swipe to remove a sample or swap a new one automatically. You can also solo specific loops (or mute them) by holding down the key.

Once you’ve created a loop, it’s easy to share it on TikTok, and the ability to export as an Ableton-ready project file is coming soon. We’ve attached an example of what a creation looks like when shared via links, showing the end result and the sounds used.

Splice has countless millions of samples, so sifting through them to find good stuff can be tedious, especially if you’re not sure what you’re looking for or want to avoid overused samples. Still, the app could be a good way to spark inspiration as a form of musical roulette or as a musical toy, much like the novice-friendly Orba music device.

“I think we’ll hear a richer, more diverse selection of sounds bubbling through this technology, that we might surprise creatives with new ideas,” said Ale Koretzy, who leads the ML and Audio Science innovation team. at Splice. “Some will use it to discover sounds and some will use it to create music.” CoSo is now available for Android and iOS devices.

Update 5/3 at 8:55 a.m. ET: The story has been updated to clarify that Ableton exports are not live yet, but “coming soon” according to Splice.
