Magnio
Read full descriptionHide full description
Where magnetism meets melody. Magnio turns the iPhone already in your hand into a living instrument. Held sideways like a game controller, it answers to your hands: touch the screen to wake the sound, then tilt, swipe, and push to give the music its shape. PLAY WITH MOVEMENT • Tilt the phone up and down to move through notes. • Flick your playing thumb sideways to bend a note into its neighbour. • Push the phone away from its centre to open the sound. CATCH THE VIBE Tap Vibe and Magnio listens to the room. Within seconds it finds the key of whatever is playing — a record, a jam, a friend at the piano — and tunes itself to it. Your very first note already belongs. No theory, no menus, no guessing what key you are in. NOTESEER: INTUITIVE NOTE INTELLIGENCE NoteSeer blends mathematical balance and the intuition of probability, learning from your musical aesthetic. It follows your chosen scale and playing to guide note choices. Shape its influence and learning in its own menu, or turn it off whenever you want. Everything happens on your device. BUILD A PULSE Choose a scale and octave. Add bass, arp, kick, and offbeat hat. Shape two-bar patterns, tap the tempo, and let sidechain make the sound breathe. RECORD AND SHARE One round button records what Magnio itself is playing — never the microphone, never the room. Recordings are named by date, and you can rename, play, share, or delete them from the list. CREATE YOUR OWN SOUND Blend sine, square, triangle and sawtooth waves. Adjust each wave's frequency components, name your instruments and save them on your device. Hold the fingerprint in the editor to play while shaping your sound. SHAPE THE RESPONSE Fine-tune Natural and Wah with modulation range, response curve, dead zone, reset-on-touch and note-lock settings. An optional quiet release echo follows the notes as you move, with adjustable delay and presence. MAKE IT YOURS Choose right- or left-handed playing; the whole instrument turns with you, so you simply flip the phone. Calibrate each gesture, tune the response, and arrange your performance surface — place the controls where your thumb wants them. GO FURTHER WHEN YOU WANT Play Magnio's own voice, send MIDI to another app on your iPhone, connect to a Mac over USB, or use BLE MIDI with a compatible Mac or iPad app. PRIVATE BY DESIGN No account. No ads. No analytics. No tracking. Vibe listens on device; audio is never saved or uploaded. Your settings stay on your device. Magnio is free. Every sound, gesture, and MIDI route is available. There are no subscriptions and no in-app purchases. The instrument was already with you. Now play it.

Gold Star Studio is the room in your pocket, from SugarHill Recording Studios - Houston's oldest studio, recording since 1941, where Gold Star was the name on the door. Eight tools, every one built from scratch at the studio. Nothing is sampled: every sound the app makes, it makes itself. KEY FINDER - play a song at the phone and it tells you the key, spelled the way a chart spells it. TUNER - chromatic, or set to guitar, bass, ukulele or violin with their tunings. Lock a string, hold it to hear the note, set the reference pitch, or match the tuning of a recording. TEMPO TAP - tap along and read the tempo. METRONOME - a woodblock click with the meters you need, tap tempo, a screen flash and a vibrate that you can feel, and it keeps time with the screen locked. THEREMIN - play it with the light on the front camera: a hand over the lens bends the note. Filter, echo, tremolo, crush and vibrato on the pad. PIANO - a piano, a Rhodes, an electric piano and an organ, with sustain and chords. DRUM MACHINE - an 808 kit with grooves and fills. AUTO-TUNE - sing into it and it pulls you to the key, hard or natural, with a harmony and a room. Find the key of the track first. And the SUGARHILL ARCADE, three machines of the studio's own: REELZ, the pinball - five light shows, a golden ticket, Reel G on the head calling the shots, and a gold star ball; STAR SHOOTER, where the studio's gear comes at you in waves; and GOLD STAR GP, a hover racer with eight machines, four tracks, upgrades, rivals, hidden paths and a live synth soundtrack - steer with a tap, swipe up for nitro, and hit it on the beat. Wear an Apple Watch and it becomes the remote: start the metronome from your wrist and feel the beat there, tap a tempo, see the note the theremin is playing, read the pinball score, and nudge the table. Gold Star Studio listens through the microphone only while a tool that needs it is open, and uses the camera only as a light meter for the theremin. Nothing is recorded and nothing leaves the phone.
