LEJON
Performance sampler
Load an audio file and LEJON finds the tempo, key, beats and maps across your keys for instant sample chopping and music making.
Features
LEJON is a performance sampler that finds the true beat grid and lays out slices so you can start triggering ideas immediately.
Time & Pitch
Stretch to host tempo and shift pitch freely without changing speed. Auto-detects key.
Beat-Aware Auto Slicing
Finds the true beat grid (live or machine) and lays out slices perfectly on the rhythm.
Playable Key Layout
White keys (C2–B3) trigger slices so you can explore and replay parts of the song instantly.
Live Performance
Black keys trigger functions like looping, reverse, and retrigger while the audio keeps running.
Stem Extraction
Split any song into drums, bass, vocals, and instruments so you can use each layer on its own.
Step Sequencing
Create rhythmic patterns for each sound using a step sequencer shown as a piano roll.
Scratch & Effects
Perform preset DJ scratch patterns (Flares, Crabs) and tape-style slowdowns live.
Real-Time Engine
Designed for continuous play. Interact rapidly and manipulate audio without stopping.
$20 while in beta
Lejon is only $20 during beta and currently runs on MacOS (Apple Silicon). If you sample full songs and want to have some real fun with it, this is the quickest way to start.
