A Theremin.app Alternative for Chords, Layers and WAV Export
Compare Browser Theremin App vs WeldSynth. Facts only, no marketing fluff.
FACT SHEET
WHERE WELDSYNTH WINS
Recording is the point: browser theremins are fun for 15 seconds, then the tab closes and the idea is gone. WeldSynth keeps four layers and welds them.
Two hands, two roles: harmony on the left, expression on the right. Most browser theremins track one hand doing one thing.
Current-generation tracking: WeldSynth uses the latest MediaPipe Hand Landmarker with GPU delegate, not the legacy CDN builds that make older toys stutter.
WHERE IT DOESN'T
The classic browser theremin wins on purity: one pitch, one hand, zero learning curve, and some are fully open source. If you want exactly a theremin and nothing after it, that simplicity is real. WeldSynth trades a few minutes of learning for an instrument you can keep.
FAQ
Is WeldSynth harder to play than a browser theremin?
The first chord takes about a minute: one finger is the root, five fingers is the fifth. The Beginner Academy walks you through it with in-page practice panels.
Can a browser theremin record?
The well-known ones cannot — that is the gap WeldSynth was built to fill. Record layers, weld them into a loop, export WAV.
Does WeldSynth work without a camera?
Yes, Mouse Mode gives you the full synth engine with pointer control — still more recording depth than any camera theremin toy.
