Jason Donnelly, aka DJ Puzzle, shared this preview of his presets for Audiokit Synth One – a new free and open source synth for iOS.

The demo, embedded above, showcases not only Donnelly’s presets, but the capabilities of the powerful new synthesizer.

“I created everything in the demo with just Synth One and my DAW,” he notes. “All the sounds were created from scratch, including the drums.”
