The people behind the sounds

Sounds & credits.

Good instruments start with good sounds. Tapkit uses the recordings below, together with its own electronic sounds and artwork. The licenses for these assets are independent of the app’s code.

Piano

The 21 MP3 files are unchanged. Playback trims quiet lead-in, normalizes levels, limits tails to seven seconds, adds short fades, and repitches samples to cover the keyboard. File details · Full license.

Djembe

Artwork & this demo

Instrument and hand illustrations were generated for Tapkit with OpenAI image generation. Sampler and marimba frames, their live pads and bars, and the Tapkit mark are original vector and code artwork. This site converts the PNG illustrations into smaller transparent WebP images; it uses the app’s sound engine, instrument geometry, and animations in a browser adapter.
