Built for TommyWho Records · Playback powered by the Web Audio API on hosted MP3 files, with real-time pitch-preserving time-stretch (SoundTouchJS). BPM & Key pulled from the Serato-analyzed catalog. Real 3-band EQ, real waveform (drawn from the decoded audio), and real channel fader volume control. BPM Sync and Key Sync are fully independent — tempo and pitch can be adjusted separately, so both can be active on the same deck at once, same as Key Lock in Serato/Rekordbox. Load tracks by pasting a direct MP3 URL, or via the browser below once mp3Url is filled in per track. Auto Cue detects the first beat on load and skips leading silence — hit SET CUE any time to override it manually. USB MIDI controllers work via the MIDI panel below the browser — connect, click LEARN next to a control, then press/move the matching button or fader on your hardware.
