Synesthesia Synth vs PocketStrum

Synthaestesia is a free experimental audio-visual instrument. Three capsules float in space. Every contraction produces sound. Move them, rotate them, reshape their pulse — and sculpt evolving spatial audio. Position changes tone. Rotation alters texture. Delay generates synchronized particles. This is not a game. It’s a spatial synth you can see.

The beloved electronic autoharp of the early '80s — the strum-anything wonder heard on records by Gorillaz, David Bowie and Brian Eno — reborn as a pocket instrument anyone can play in seconds. Press a chord button with your left thumb. Sweep your right thumb across the SonicStrings-style strumplate. That's it — you're making music. Every string is always in tune, because the plate re-tunes itself to whatever chord you're holding.
