Raise a hand
Start camera access, keep the wrist and fingertips in frame, and hold a clear one-to-five-finger pose. Hand height changes intensity while the finger count selects the chord degree.
Gesture Synth Weld
Open the instrument. Land the next chord on time.
Looking for Gesture Synth Weld? Play chords with hand gestures, keep each change on beat, complete a four-bar challenge, and export WebM or MIDI.

One link. One working path.
This search phrase usually appears when someone wants a hand controlled instrument in the browser. This page sends you straight to Gesture Synth, where the playable stage is already on the homepage. There is no second download page, account gate, or setup form between this page and the instrument.
Some searches use phrases such as gesture synth weld vercel app or gesture synth vercel. The wording may change, but the next useful step is concrete: open a browser instrument and make sound. This page keeps one destination—the Gesture Synth homepage—so its play buttons do not depend on a third-party host. Choose camera or no-camera input there, then start with one chord before changing key, scale, sound, or recording format.
Follow the main button to the homepage. Choose Start with camera if you want hand tracking, or Try without camera for the fastest first sound.
Hold up one to five fingers, tap a chord pad, or press a number key. Every input reaches the same chord engine.
Stay in Free Play to explore, or run the four-bar challenge to receive Match, Timing, and Stability scores with local WebM and MIDI options.
You do not need to configure every control before playing. Gesture Synth Weld can begin from camera input, but the same musical map is available through mouse, touch, and keyboard controls. Pick the route that fits the device in front of you, then change one setting at a time after sound starts.
Start camera access, keep the wrist and fingertips in frame, and hold a clear one-to-five-finger pose. Hand height changes intensity while the finger count selects the chord degree.
Mouse Mode removes camera permission and tracking from the first run. Use the visible pads, number keys, mouse movement, or touch input to learn the same chords.
Challenge mode gives you a four-beat count-in and sixteen scored beats. Free Play keeps the controls open when you would rather build a loop or test a progression.
The instrument is organized around a small set of visible actions. It does not require a MIDI keyboard or installed synthesizer. Web Audio makes the sound, the browser handles input, and the result stays on the device unless you choose what to do with a downloaded file.
| Task | What you use | What you get |
|---|---|---|
| Play chords | Camera, mouse, touch, or number keys | Chord degrees I–V in the selected key and scale |
| Keep time | Beat Lock and the Next chord readout | A stable gesture queued for the next musical boundary |
| Practice | Four-bar challenge and result timeline | Separate Match, Timing, and Stability feedback |
| Keep a take | Local browser recording and MIDI generation | WebM when supported, plus standard MIDI after a challenge |
Camera tracking and musical timing solve different problems. A camera reads a stream of small hand movements, including the corrections made while forming the next pose. Music needs a clear decision about when the next chord begins. Beat Lock separates those two moments.
The tracker first waits for a stable gesture, shows it as Next, and schedules the change against the Web Audio clock. The current chord keeps playing while you prepare. When the beat boundary arrives, the queued chord becomes Playing. Free Play also offers Instant mode when direct response matters more than a grid.
A webcam is optional here. Open the homepage and choose Try without camera. The stage switches to Mouse Mode without opening a camera permission prompt. Tap a chord pad on a phone or tablet, click a pad with a mouse, or use number keys 1–5 on a physical keyboard.
The fallback is not a separate demo. It uses the same sound engine, challenge targets, score, result timeline, and export flow. That makes it useful for learning the progression before adding hand tracking, for devices without a webcam, and for recovering when a browser blocks camera access.
An open instrument is easy to try and easy to leave. Gesture Synth Weld adds a short finish line: four bars, a visible target, and a result that explains what happened. Match checks whether the requested chord was playing. Timing checks when a correct change arrived. Stability checks whether extra confirmed changes appeared between scored beats.
After the run, the sixteen-beat timeline shows Target and Played values side by side. Supported browsers can save the visible stage and generated audio as a local WebM file. MIDI export preserves the beat-locked chord events without including camera frames or hand landmarks. Recording support varies by browser, so MIDI remains the fallback when video capture is unavailable.
Web browsers normally keep audio paused until the page receives a click, tap, or key press. A silent first screen does not necessarily mean the synthesizer failed. Open Gesture Synth, interact with a chord control once, and then check the sound state.
If camera startup fails, the homepage keeps the no-camera route available. Camera and recording APIs differ across browsers and devices; Mouse Mode and MIDI prevent those differences from turning the entire page into a dead end.
Gesture Synth Weld on this site is an independent path into Gesture Synth, a browser instrument built around one-hand chord control, Beat Lock timing, scored challenges, and local exports.
No. This is an independent gesture synth with its own one-hand controls, Beat Lock, challenge scoring, Mouse Mode, and export flow.
Yes. Open Gesture Synth, choose Try without camera, then use the chord pads, number keys, mouse, or touch input.
Browsers require an interaction before starting Web Audio. Open Gesture Synth, press a chord pad or a number key, confirm Sound is on, and check the tab and system volume.
Yes. Complete a challenge and export a standard MIDI file containing the beat-locked chord events.
Gesture Synth Weld is ready
Start with camera input or choose Mouse Mode. Both paths lead to the same instrument, challenge, score, and local result options.
