Gelato Synth
No wrong notes. Just play.
Free · In‑App Purchases
Free to play. One unlock opens chord buttons, every sound, the loop recorder and your own sound library.
Gelato Synth is a chunky, friendly synthesizer for iPhone. Pick a sound, tap the big pads, and it sounds good straight away, because every note is already in key.
NEVER PLAY A WRONG NOTE
Choose a key and a scale and the pads rebuild themselves. Every button is a note that fits. Slide across them, hold them, stack them. You cannot hit a clunker.
MAKE A SOUND THAT IS YOURS
Real FM synthesis with two oscillators, noise, an envelope, a filter, an LFO and effects, all on big sliders you can understand. Watch the wave change on the scope as you move them. Start from one of 52 sounds or from a blank slate.
PLAY CHORDS WITH A BUTTON
Switch to Chords and the pads become the chords of your key: triads, sevenths, ninths, sus and power chords. Whole chords under every finger.
RECORD YOUR IDEA
Tap record for a quick take, or set a tempo and a beat and loop it. Add another layer on top with +1, up to eight, each with its own sound. Mute, balance and share the mix.
BUILD YOUR LIBRARY
Save the sounds you make into My Sounds and they are there next time. Drop your own drum hits into the Files app and the beats use them.
WHAT IS FREE
Notes mode with every scale, a handful of sounds in each category with all the sliders, and quick record.
THE FULL LIBRARY
One purchase, yours forever: chord buttons, every sound, the loop recorder with beats and layers, and saving your own sounds. No subscription, no ads, no account.
Gelato Synth is made by a tiny team who wanted a synth their friends could pick up without a manual.

Ratings & Reviews
A quick tour on first launch shows you around: pads, chords, sound shaping, loops and saving. Tap the ? on the scope any time to see it again. Chord names are now spelled properly, including 7ths, 9ths and sus chords, with flats in flat keys. A new launch screen, and small fixes throughout.
