Touchophone - Synthesizer

A fun little synthesizer that fits in your pocket. Play notes, twist knobs, make weird sounds. Great for music lovers and curious kids. No ads, no in-app purchases.

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

• 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
