MicroFreak DJ Mode · play a song, capture it, jam it out over MIDI

🎚 Song → tab audio → MIDI notes

Start capture — Chrome asks what to share. Pick the Chrome tab that's playing music (this one, if you use the embed below) and tick “Also share tab audio”. No tick = silence. macOS Chrome can only share a tab's audio; on Windows “Entire screen” shares all system audio. Spotify has no audio API — tab capture is the only way a web page can hear it.
Connect MIDI — plug the MicroFreak in over USB, click Connect, pick its port + channel.
Arm output — until you arm, the tracker just displays what it hears. Armed, every detected note streams to the synth. Jam over the top.

Web MIDI needs a click (browser rule) — connect when the Freak is plugged in.

🎛 Musicality

Key Scale snap

Octave shift Smoothing

Gate threshold −34 dB

Gate keeps silence from spraying notes (open at threshold, close 6 dB lower). Scale snap pins wobbly pitch to the song's key. Smoothing trades a frame or two of latency for stability.
