Toaster listens to whatever is playing and writes it as live Strudel code: kick, clap, hats, bass line and chords, lit up as the song hits them, over scenes that move with it. Spotify search in the apps. Free, open source, in a browser or on Mac and Windows.

Hi, I'm Colin, and I made Toaster.
You play a song and Toaster writes it out as live Strudel code while it plays: a line each for the kick, clap, hats, bass line and chords, each lighting up when the song hits it. Press O and the code opens in strudel.cc, ready to play and change. There's no AI model in the listening, just signal processing.
It's a sketch of the song, not a transcription. It does best with a steady beat, the sounds are stand-ins (a 909 kit and a few synths), and its weak spots are a kick under a busy bass and a song's first drop. I'd love to hear which songs it fumbles.
The site's first button plays a demo song, no sign-up. The Mac and Windows apps hear whatever your computer plays, and if you connect your Spotify (with your own free client ID, steps in the README) you can search it and browse your playlists from inside Toaster (the music plays in the Spotify app), with a little mini player. There are scenes, dominoes for every hit, and NASA's footage of the Earth from the space station to watch it over.
Turn the camera on and you work it with your hands: frame something with your fingers and a filtered window opens between them, make a circle and a portal opens. In the apps, X saves what it has heard so far as a MIDI file and Strudel code.
It's free and MIT licensed. Thanks for looking, I'll be around to answer questions.
