- Automatic tempo and transient detection
- Tap-based chopping with snap to transient
- Pad-based sample playback
- Spin, brake, and scratch platter simulation
- Time-stretch and warp to grid
- Split songs into drums, bass, vocals, and other stems
- Export sampler projects, DAW sessions, and WAV files

Julienne is a record you can cut. Load a sample and Julienne finds its tempo and its transients on its own. Chop it where you hear it, play the chops from the pads, spin and scratch the platter with your finger, and warp anything onto a grid without touching its pitch. Then take the whole session — chops, tempo and order — into wherever you finish tracks. CHOP • Tap the waveform to lay a chop; SNAP pulls it onto the nearest transient • Nudge, trim, reverse and rearrange — a pad is a slot, not a fixed chop • GATE, NOTE and NEEDLE decide what a pad does while you hold it • LOCK CHOPS keeps your chops in place while you play them PLAY • Drag the platter to spin, brake and scratch, with the weight of a real one • 33 and 45, varispeed, reverse • Time-stretch and warp to a grid with the pitch left alone STEMS • Split any song into drums, bass, vocals and other, right on your iPhone or iPad (iOS 16 or later) • Play while it splits; mute and solo stems on the deck, and chop and export what you hear EXPORT • Sampler projects, DAW sessions and plain WAV — the export sounds like the session, because both come out of the same engine • Add your chops straight into a project on your MPC Sample's card • Everything lands in Files, or goes straight out through the share sheet CRATES • Keep records in crates, and send them between your computer and your phone over Wi-Fi PLUGIN • Julienne runs as an Audio Unit (AUv3) inside AUM, Koala, Logic and other hosts, so the deck lives in your session MIDI • Play the pads and turn the controls from any MIDI controller, wired or Bluetooth • Learn any control by moving it FREE AND PRO Julienne is free to load, chop, play and run as a plugin. One purchase, once, unlocks stems, exporting and crates — and it follows your account onto every device you sign into, phone and computer alike.

Draw a structure you can play. Hear it sing, then record how you change it while it rings. Sound With Bones is a physical modeling instrument built from your drawings. A sketch becomes connected joints whose mass and stiffness shape the sound. Pluck a joint, cut a ringing connection, then repair it and hear the structure change. HEAR YOUR DRAWING SING Tap Listen and your drawing plays a whole song, tuned from its own resonances. Change the shape and the same song sounds new. Soft Geometry, an original, and Twinkle, Twinkle are free. SHAPE SOUND BY LISTENING Choose a brighter or less bright sound. The Workshop proposes small changes to a joint's mass or a connection's stiffness. Compare each edit with the same strike, reference pitch, duration and listening level. Keep a version or return to your original. CHANGE THE INSTRUMENT AS IT PLAYS In Workshop > Perform, record the strikes, cuts and repairs you play. Keep the take as editable actions on a beat timeline. Move an action, adjust the tempo and replay it from the drawing captured at the start. A cut changes the sound already ringing. You can also arrange actions by hand. With Plus, export the performance as WAV with its editable workshop. MAKE A FAMILY OF RELATED SOUNDS Create soft, firm, edge and broken variations from one drawing. Edit the strike location, force, softness and connection cut, and hear each one. With Plus, export named 24-bit stereo WAV files at 48 kHz together with the workshop, drawing and recipes. PLAY WITH TWO HANDS Hold one joint while another finger plucks the shape. Damp removes energy where that joint moves. Pin constrains the held joint and changes its resonances. Release it to hear the original structure again. LEARN BY LISTENING Predict what lighter joints will do, hear the natural resonance change, then try an unfamiliar drawing. Isolate one vibration mode or listen to local damping. Save your prediction, measured result and both sounds. Reopen the exact comparison even after changing your current drawing. These experiments use the same physical model as your instrument. BRING YOUR DRAWINGS INTO A MUSIC APP The included AUv3 instrument responds to MIDI notes, velocity and sustain in compatible hosts. Open an exported drawing or workshop in the plug-in. Its drawing is saved with the host project. KEEP YOUR WORK Save instruments, recordings and workshop versions locally. Share editable drawings and workshops through Files. Export recordings as M4A, or import supported audio into your library. Imported recordings remain audio clips; they do not become physical instruments. SOUND WITH BONES PLUS Drawing, playing, cutting, recording, saving, sharing, Workshop comparisons, performances, learning and the AUv3 instrument are free. Plus adds: • 8 more songs, including Für Elise, Canon in D, Bach's Prelude in C and Gymnopédie No. 1 • 8 sculpted shapes: Ribcage, Wishbone, Shell, Bell, Harp, Kalimba, Star and Web • Recordings up to 10 minutes (free recordings stop at 1 minute) • 24-bit WAV export of sound families and Workshop performances • New songs and shapes as they are added Plus is available as a yearly subscription with a 7-day free trial, a monthly subscription, or a one-time lifetime purchase. Payment is charged to your Apple Account when you confirm, or when the free trial ends. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings. No account or microphone access is required. Synthesis and recording run on your device. Synthesized sounds come from the drawing's physical model. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://sound-with-bones.netlify.app/privacy
