Make a sound in seconds—and shape it while it plays. Pixelsynth turns taps, drags, melodies, and chords into a colorful instrument you can understand by watching it. Everything you play lives on one screen. Touch a note and start exploring. FROM THE DEVELOPER OF PIXELBOOP Pixelsynth is a new visual instrument from the maker of Pixelboop. Both apps share a love of playful grids, immediate feedback, and musical ideas that begin with one touch. PLAY FIRST. LEARN BY WATCHING. Sixteen pads invite you to find a melody, hold a chord, or strum across the screen. Notes light up as you play, and every sound control moves in front of you. You can see what each gesture is doing while you hear the result. SHAPE THE SOUND LIVE • Switch waveforms to change the character of your sound. • Sweep the filter from bright and open to soft and focused. • Shape attack, decay, sustain, and release for crisp plucks, swelling notes, and long tails. • Add motion with LFO, repeating echoes with delay, and depth with reverb. Each control is a colorful tank. Touch higher or lower inside it to set the value directly. Values in the upper half stay where you leave them; notes in the lower half drain away after you lift. It feels immediate because the picture and the sound follow the same gesture. MADE TO BE SEEN Created by a Deaf musician, Pixelsynth treats visual feedback as part of the instrument. The entire musical surface is drawn on a 40 by 24 pixel grid—just 960 pixels—so every control stays visible and every change has a visual response. PLAY IT YOUR WAY Open Pixelsynth as a standalone instrument on iPhone or iPad, or load the included AUv3 instrument in a compatible iOS music host. Your host can send MIDI notes and save the instrument state with your project. A compatible host is available separately. FREE TO EXPLORE No account. No in-app purchases. No third-party ads.

A frozen cathedral beneath the ocean. A dark night in the city. A garden in the clouds. Atmospheres 2 turns your words into creative reverb spaces. Describe a place, a material or a feeling, then hear how it transforms your guitar, vocals, synths or any other audio. Let your imagination lead. Each prompt inspires a sonic interpretation, with room to explore spaces that could only exist in your music. MAKE A LITTLE MAGIC Type a prompt and create an atmosphere. Try something familiar, something surreal, or a combination of both. English prompts work best. LET RANDOM SURPRISE YOU Tap Random to generate a phrase and a new reverb space. Your Mix stays where you left it, so you can explore without changing your dry/wet balance. ONE KNOB, EASY TO EXPLORE Use the central Mix knob to blend your original sound with the atmosphere you've created. APP + AUv3 Use Atmospheres 2 as a standalone app for live audio input, or load its AUv3 effect in a compatible music app. Your generated sound and Mix are recalled with your host project, including when you copy the plugin to another track. The standalone app remembers your last sound. ENTIRELY OFFLINE Prompt generation and audio processing run locally on your device. No internet connection or account is required. BORN FROM DEEP WATERS 2 Built on the reverb engine behind Deep Waters 2, with water-inspired textures and a simple interface made for exploring. Atmospheres 2 is an audio effect: it processes incoming audio. For standalone live monitoring, use headphones or an audio interface. AUv3 use requires a compatible host app. For iPhone and iPad. Requires iOS/iPadOS 16 or later.
