The moment it finally clicks. There is a song in your head. Between you and it: learning chords, drilling scales, getting your fingers to obey. By the time you could play it, the idea is long gone. Chordyne turns that around. Pick a chord with your left hand. Play with your right. Everything you touch fits. There are no wrong notes, because none of them are on the surface. Ten seconds in, you sound like someone who has been doing this for years. YOU PLAY, THE BAND FOLLOWS Bass, drums and arpeggios lock onto the chord under your finger. You change it, they come with you, in time, with nothing to set up first. One finger turns into a whole arrangement. YOUR IDEA SURVIVES THE RIDE HOME The best hook shows up on the bus, on the sofa, at half past one in the morning. Record a loop, let it run, stack the next part on top. Four song sections you jump between while you play. What was humming a minute ago is a track now. YOU START HEARING WHY MUSIC WORKS Under every pad sits the role that chord plays in the key. You never have to read it. But one day you notice it anyway, and suddenly you know why that one change in the chorus hits so hard. The borrowed chords are right there for the moment you want to catch people off guard. ONE TAP, A COMPLETELY DIFFERENT MOOD Warm eighties synths. Jazz voicings where every chord sounds like a bar at midnight. A Persian set with notes a piano does not even have. You pick a feeling, and the rest falls in behind it. ALWAYS WITHIN REACH On the iPhone on your commute. On the iPad when you mean business. On the Apple Watch for the melody that arrives while your phone is in your pocket. BUILT AROUND YOUR HANDS Keys you still hit when the bus brakes. Nothing flashes, nothing nags, nothing wants an account from you. Open it, press a chord, go. Whether you have played for thirty years or never held an instrument: after the first minute you will not want to put it down. Made in Germany by Akustikrausch.

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. The instrument works offline. The standalone app may occasionally show developer news or an introduction to Pixelboop, which you can close immediately. Pixelsynth does not track you or collect the music you play. Open it. Touch a note. See where it takes you.
