Chords Weaver
Read full descriptionHide full description
Chords Weaver is a hands-on chord instrument you play by ear. Pick a note on the keyboard and it filters to the chords that fit. Choose one, and two pads open up: one shapes its voicing (spread, inversion, octave) while the other suggests where to go next, the right side resolving, the left adding tension. Build a progression on the timeline, and a live piano roll shows exactly what will play. Press play and the progression comes alive with arpeggios, block grooves and strums, each chord ringing in time. Turn on Drift and the voicings slowly wander on their own, so the loop keeps evolving. MORE - Rich arpeggios: ascent/descent, ternary grooves (waltz, shuffle, jig 6/8), a lilting 7/4, and sparse syncopated patterns (charleston, tresillo, offbeat, push). - MIDI Out to your synths, DAW or hardware, with a 24 PPQN clock. - Four scenes, copy and paste, and a "roll a matching bridge" helper. - Optional cloud save: sign in and your progressions follow you to every device. The app works fully offline. - Five languages: English, Français, Español, Русский, 日本語. Free to download. Weaving, voicings, playback and saving are all free. A one-time Pro unlock adds MIDI/WAV/text export and live MIDI-out. No ads, no subscriptions. Signing in is only for optional cloud sync.

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

Verdict
The clearest difference is in-app purchases: Sound With Bones at none against Chords Weaver's 1. Chords Weaver's advantage is iOS requirement (15.0 vs 18.0). On price, update cadence, ads and device support there is nothing between them.
