Magnetic Echo is a vintage-inspired multi-head tape delay and spring reverb effect for iPhone and iPad, built for warm echoes, ambient trails, dub feedback, and evolving analog textures. Inspired by classic tape echo machines of the 1970s, Magnetic Echo combines the movement and imperfections of magnetic tape with the flexibility of a modern AUv3 plugin. TAPE DELAY Three playback heads create layered and rhythmic repeats, from short slapback echoes to spacious multi-head patterns. SPRING REVERB A dedicated spring tank with adjustable decay and tone, for that unmistakable splashy, metallic space. WOW & FLUTTER Real tape isn't perfect — subtle pitch drift and mechanical wobble give every repeat organic character. FEEDBACK & SATURATION Push the feedback path from gentle repeats into self-oscillation, with saturation adding color and character on every pass. FROM DUB TO AMBIENT Create warm guitar echoes, psychedelic textures, washed-out ambient trails, rhythmic delays, and dub-style feedback. HOST READY Works as an AUv3 Audio Unit plugin inside AUM, Audiobus, GarageBand, Cubasis, Logic Pro for iPad, and any other AUv3-compatible host. %100 FREE No subscriptions, no in-app purchases, and no ads.

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.
