Just movement and imagination. INSTRUMENT LAB — AI Instrument Creation Describe your dream sound in words and let AI generate a custom instrument for you.

Save your creations to your personal library and regenerate variations anytime. JAM MODE — Play Together in Real Time Connect with friends over WiFi and make music together.

Each player gets personal mixing controls and walks away with their own recording of the jam. LOOPER — Your Motion Music Studio Layer instruments to build complete tracks right from your phone. Choose between automatic rhythm detection or set your own tempo with the metronome. Mix each layer with volume and pan controls, overdub to add depth, and save sessions to pick up where you left off. Export your creations as audio for DAWs and streaming, or as video showing your layer-by-layer performance — perfect for social media and portfolios. PRACTICE ARENA — Learn by Playing Master your motion skills with interactive lessons. Watch a demo, then play along to songs. Earn up to 3 stars per lesson as you improve.

Foundry is a sampler for producers who want to get right to chopping. Import a track from Files, and Foundry finds the tempo, key, and downbeat automatically. Slice it on a beat grid with draggable markers, audition each slice, and retune or restretch it to your project tempo, repitch for that classic sampler feel, or stretch to keep the key. Then play. Sixteen velocity-sensitive pads, a count-in, and a loop of any length. Arm, record, and your performance lands on a timeline where you can nudge hits, quantize them to a grid with adjustable strength, and bounce the result to a WAV in Files. CHOP • Automatic BPM, key, and downbeat detection • Beat-grid slicing with draggable markers and a minimap • Loop finder that confirms the grid on tricky tracks • Per-slice pitch, type, and length editing • Repitch or time-stretch slices to follow the project tempo • Project-wide transpose PADS • 4×4 pad grid with a scrolling waveform playhead • Adjustable loop length and count-in • Arm + record transport TIMELINE • Every hit recorded as a dot on its lane • Drag single hits or whole groups • Quantize grid and strength • Bounce takes to WAV, share to anywhere Sessions save automatically and pick up where you left off.
