## What is Touchophone?

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.
