Instrument Lab

Ten instruments and not one audio file. Every sound is computed from a physical model of the object — so you can reach in, change the object, and hear it on the very next note.

Nothing leaves this page

No upload, no server, no account. Every sound is computed in this tab, and the files you download are written here too. Unplug the network and it all still works.

Ten for this instrument

All public domain. Play one to load it into the take, or hold it to loop on its own instrument — then pick a second one and play over the top.
