About Hi Organ
Hi Organ turns your iPhone or iPad into a real arranger keyboard - the kind of instrument where you hold a chord with your left hand and a complete backing band plays along with you. WHY HI ORGAN Most keyboard apps give you a piano and stop there. Hi Organ gives you the whole instrument: four keyboard parts, an auto-accompaniment engine with eight independent tracks, a mixer, effects, drum pads, and recording. Everything you would expect from a hardware arranger is brought together in one app, with controls arranged in a familiar, performance-focused layout. Hi Organ is also designed to feel at home on the latest Apple devices. On iOS 26 and later, the app features a dedicated Liquid Glass interface with translucent panels, layered depth, soft reflections, dynamic highlights, and responsive glass-style controls. The result is a cleaner, more immersive workspace that keeps important performance controls easy to see while giving the instrument a distinctly modern iOS look. Whether you are practicing, arranging, performing, or simply exploring new sounds, Hi Organ combines the depth of a full arranger keyboard with a visual experience built for the newest generation of iOS. THE KEYBOARD - Full 88-key range with smooth scrolling and zoom - Adjustable split point: left hand plays chords, right hand plays the melody - Three upper layers plus a lower part, each with its own voice, volume, octave and pan - Multi-touch with glissando, and velocity that follows where your finger lands - Note names as letters, solfege or numbers - or hidden AUTO-ACCOMPANIMENT - Eight tracks: drums, percussion, bass and five accompaniment parts - Intro, four variations, fills, break and endings - exactly like the hardware - Start/Stop, Synchro Start, Synchro Stop, Tap Tempo, Fade In/Out, Auto Fill - Chord recognition covering major, minor, sevenths, sus, diminished, augmented, slash chords and more - The accompaniment follows your chord in real time YOUR OWN STYLES - Import style files (.sty, .pst, .bcs) with full CASM support, so chord transposition follows the rules the style was authored with - Import standard MIDI files and map the tracks yourself - Bring files in from the Files app SOUNDS AND CONTROL - 128 General MIDI voices plus drum kits - Nine-fader mixer for keyboard parts and accompaniment tracks - Reverb, chorus, filter cutoff and resonance, ADSR envelope, portamento, shake and repeat - Sixteen drum pads and four assignable phrase pads - Metronome, transpose, octave shift, tempo lock - Four keyboard sets to store and recall your whole setup RECORD AND SHARE Record what you play, listen back, then export it as an audio file or as MIDI to keep working on it elsewhere. PREMIUM Hi Organ is free to play. A single one-time purchase - no subscription - unlocks unlimited style imports, all 128 voices and drum kits, recording and export, the advanced effects section, and removes ads. Buy once, keep it forever, on every device signed in to your Apple ID. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
