Code, play, change

Music is Strudel. Press Play, change a pattern, then Update or ⌘/Ctrl Enter in its editor. Use Update music block in the project menu or ⌘/Ctrl Shift Enter to run the blank-line-separated block at the cursor. Give patterns names such as drums: to replace them on the next block run; anonymous $: labels are not supported in block mode. Add .pianoroll(), .scope() or .spiral() to see a music drawing below the code.

Visuals is GLSL. Edit Image and Update to change the picture. Use ctKick for a pulse from the kick drum. Buffer passes and Channels are optional. Channels can use image URLs, music audio, keyboard input or buffers. Click the output to use keyboard input; image URLs remain external links in saved projects.

Open Chat to ask for music, visuals, or both. A proposal changes nothing until you Apply it. Undo restores the previous source.

Standard Strudel drum banks, piano, instruments and soundfonts load online as you play. Try s("bd*4").bank("tr909") or note("c4 e4 g4").piano(). Sound credits

Add sample in the project menu imports a WAV. Give it a name, then play it with s("name").
