About Gesture Synth Weld
What is Gesture Synth Weld
Gesture Synth Weld is a free, browser-based hand gesture music synthesizer that runs entirely in your web browser. Using your webcam and MediaPipe hand tracking, it creates a two-hand musical instrument: your left hand controls harmony (key, scale degree, major/minor toggle) and your right hand controls expression (chord type, volume, tone, and octave). No downloads, no MIDI controllers, no plugins required. Choose from 3 modes: Gesture (two-hand chord playing), Theremin (continuous pitch and volume control), and Mono Piano (single-note melody). Enable the Arpeggiator to sweep through chord notes like a harp, or toggle Auto Bass for an automatic low-end foundation that follows your harmony. Record up to 120 seconds of your performance — audio, full video, or privacy-friendly skeleton animation — ready to download or share to social platforms. All processing happens locally on your device — your camera feed is never uploaded to any server.
Key features
Gesture Synth Weld offers a unique set of features for gesture-based music creation. The core is its two-hand control system: left hand selects scale degrees (I–V, plus VI and VII with finger combinations) and toggles major/minor via wrist tilt, while right hand sets chord complexity (triad, inversion, 7th, 9th), volume (hand height), and tone (wrist tilt). It includes three play modes: Gesture, Theremin, and Mono Piano. The Arpeggiator sweeps through chord notes, and Auto Bass adds a low-end foundation. You can record up to 120 seconds of audio, video, or skeleton animation. The synth is powered by Web Audio API via Tone.js for low-latency synthesis and MediaPipe Hands for real-time finger tracking at 30fps. All processing is local, ensuring privacy. It works on any computer with a webcam and a modern browser (Chrome, Edge, or Firefox recommended).
Use cases
Gesture Synth Weld is ideal for anyone who wants to make music without traditional instruments or expensive hardware. It's perfect for beginners exploring music creation, educators teaching music concepts, and performers looking for a novel way to interact with sound. The gesture-based control makes it accessible for people with limited mobility or those who find traditional instruments challenging. It's also a fun tool for parties, live streams, or social media content, thanks to the recording feature that captures audio, video, or skeleton animation. Musicians can use it as a creative tool for improvisation or to add a visual element to their performances. Since it runs in the browser, it's great for quick jam sessions anywhere with a webcam and internet connection. The privacy-friendly skeleton recording is especially useful for sharing performances without revealing your identity.
Pricing
Gesture Synth Weld is completely free to use. There are no downloads, subscriptions, or hidden costs. All features, including the three play modes, arpeggiator, auto bass, and recording capabilities, are available at no charge. The tool runs entirely in your browser, so you only need a computer with a webcam and a modern browser. No account creation is required. This makes it an accessible option for anyone interested in trying a gesture-based music synthesizer without financial commitment.
