Theremin
SIDEffect's
Watchapp
Description
Play a theremin on your wrist: raise your hand for pitch, twist it for volume. Theremin turns the Pebble Time 2 into an instrument you play without touching it. Just like the original, the position of your hand shapes the sound: raising and lowering your hand changes the pitch, twisting your wrist controls the volume. The tone is synthesized in real time and played through the watch's speaker. Features - Four waveforms: sine, triangle, square, sawtooth - Vibrato in three depths or driven by the tremble of your hand - Reverb in three room sizes - Up to four octaves of range, selectable lowest note - Snap to scales: chromatic, major, minor, pentatonic, or play continuously like a real theremin - Freely assignable control axes: lift, roll or compass, each invertible - Adjustable sensitivity, portamento and volume - Automatic calibration on launch: hold the watch still for a second and you're set - Live readout of frequency and note name, with the animated waveform in the background - Noise gate switches the speaker off during silence - Every setting available on the watch or conveniently in the Pebble phone app - Seven languages (EN, DE, FR, ES, IT, PT, NL) Controls - SELECT: sound on or off - UP and DOWN: waveform - Long SELECT: settings - Long UP: recalibrate the neutral position Tip: Keep the watch still for a moment when the app starts; that pose becomes the middle of the pitch range. Tilted towards you is loud, tilted away silent. Pebble Time 2 only (needs the speaker). Compass mode is experimental. Vibe coded from start to store. That is the only reason it exists alongside a full time job. The app is free and has no ads. If you enjoy it, a coffee is much appreciated: https://buymeacoffee.com/SIDEffects
