Thank you

Much of what you hear here was recorded by other people who chose to share it. Their names, the recordings we used, and the licence each one was shared under are below. Recordings were cut, aligned and level-matched into single strokes, but the sound is theirs.

Some recordings are licensed for non-commercial use (CC BY-NC). Vibratom Studios uses them for learning and practice, not for selling. If you reuse anything from here, follow the original licence.

3D instrument models

The 3D instruments and the session drummer are models other artists shared on Sketchfab. We resized them, trimmed the file size and added the moving parts (strings, keys, knobs, the bow) ourselves; the shapes and textures are theirs. The 3D keyboard and the workstation are our own work. The drummer comes rigged; we pose its skeleton, fingers included, from the kit.
