The app that hears your scratch
Drop a timecode record, play to the beat, and the app shows every record and crossfader move — and tells you what to fix. No Serato, with the mixer you already have.
Works with your mixer
The app scans your sound card inputs and finds the record by itself. The crossfader is read over MIDI.
Call and response
The app plays a pattern to the beat, you answer in the next bars. Back and forth, in a loop — like with a teacher.
Every move scored
See your move on a graph next to the pattern: where you were early, too slow, or missed a click.
Ranking
Best scores go to a public ranking. Find out who has the cleanest flares.
Gear
You need a turntable, a timecode record (e.g. Serato CV02) and a mixer with a built-in sound card or a separate interface. Tested so far:
- Pioneer DJM-S11
- Mixars DUO MKII
- Rane Twelve (MIDI)
