95 Lofi writes complete tracks. Press write and you get 52 bars — an intro, three main sections, two lifts, a breakdown and an outro — played by a dusty-keys synthesizer and a soft drum kit, then recorded onto tape. Keys, bass, a melody line, a pad, the kit, and the record surface underneath it all. Nothing is sampled. There are no audio files in this app at all — the Rhodes, the kit and the vinyl crackle are all synthesised as they play, which is why the whole thing is a few hundred kilobytes. The music comes from chaos maths. Three Lorenz attractors shape the melody, the rhythm and the mood. Two logistic maps run underneath the drums and the bass so they wander independently of each other: turn the logistic control down and the hats repeat every bar, turn it up and they never do. Chaos on its own is noise, so a small model filters it. It is rewarded for consonant intervals and rehearses over the changes before writing. The CHAOS / TASTE slider decides how much say each one gets. Nine styles, and they are properly different. Chillhop and Jazzhop sit where you expect. Boom Bap hits harder and drier. Study Beats takes almost everything away. Drift slows to a crawl. Lo-Fi House pushes past 106. Celtic and Medieval are not jokes — modal progressions, different cadences, nothing else on the shelf sounds like them. The tape deck is the other half of the sound: a wow-and-flutter transport that never quite runs true, vinyl crackle with real pops and decaying tails, hiss, bit crush and saturation. The crackle is seeded, so the scratch lands in the same place on every play and every export. Every track is built from its seed. Write the seed down and you can have that exact track again, note for note, whenever you want it. A seed from the browser version rebuilds the same track here. You can play over it, too. The pads are the notes of the track's key rather than a piano keyboard, so nothing you touch is wrong, and the sixteen-step lane runs in time with the track and follows your host. Both play any part you like — keys, bass, melody or pad — through that part's sound and out on its MIDI channel. Choose which sections the lane plays in, just the breakdown say, and preview it without starting the track. Turn on RADIO and it keeps playing, picking a new key, mode, style, sound kit and tempo for each track. You also get: • 9 styles, 8 modes, 12 keys, tempo, swing, density and humanise • A three-layer voice: an FM tine, one or two detuned bodies, and a sub • 16 presets and 9 sound kits, from Tape Deck to Music Box, plus random patch • Six-part mixer, chorus, a long dark reverb, synced delay and sidechain pump • A tape deck: tone, wow and flutter, crackle, hiss, bit crush and drive • MIDI in, so your keyboard plays whichever part you have selected • Export a MIDI file, a WAV mix, or stems — one WAV per part plus the record surface on its own (in the app; in a host you record the audio there) • A note and a MIDI channel for every drum, not one channel for the whole kit • UI scale, so the panel is not tiny on a big iPad • Live spectrum and waveform, and the chaos engine drawn as it runs Two Audio Units, an instrument and a MIDI processor. Each part sends on its own MIDI channel and every drum has a note and a channel of its own, so one instance can drive a rack of them. The MIDI version passes your keyboard through instead of swallowing it. Both follow your host's tempo and transport, and one install registers both. The app is free and nothing in it is held back. Using the Audio Units inside other apps is a one-time purchase, and each AUv3 session plays for two minutes first so you can try them properly. No account, no ads, no subscription. Works offline.

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.
