Touchophone vs Synesthesia Synth

Touchophone turns your screen into a synthesizer. Touch the keys, twist the knobs, and see what happens. It's the kind of instrument you pick up and never want to put down. Play a melody. Stack notes into chords. Crank the filter. Add some delay and let it echo into space. There are no rules — just sounds waiting to be discovered. WHAT'S INSIDE - A 2-octave chromatic keyboard you play with your fingers - 4 notes at once — hold chords, play melodies - Sub-oscillators to fatten up your sound - A filter knob that goes from warm to screamy - Delay that repeats and fades like an echo in a tunnel - An LFO that wobbles everything in the best way - Envelope controls to shape how notes start and fade EXPRESSION STRIP - Bend notes up and down - Sweep the filter with your finger (wah!) - Add vibrato for extra flavor THE SMALL STUFF - Play with multiple fingers at once - Slide between keys - Use the expression strip while holding notes - Works on iPhone and iPad - No ads. No subscriptions. No account. Just sounds.

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.
