Before installing, visit midios.app/setup for setup instructions. midiOS is a new kind of instrument. Transform your iPhone into an expressive MIDI instrument with advanced harmony, multidimensional performance control, and deep DAW integration. Play notes, chords, scales, arpeggios, modulation, and complete live performances from the device you already carry. With Offline Play, midiOS becomes a self-contained instrument. Choose from built-in sounds, create an instrument rack, record or import personal samples, and capture performances in Offline LiveGrid—without a Mac, DAW, account, or network connection. Designed for musicians, midiOS opens ready to perform. Tap pads to play notes, chords, and scales. Change keys, modes, voicings, and tonal centers without interrupting your flow. Swipe across pads to explore inversions, chord qualities, suspensions, secondary dominants, chromatic movement, and harmonic variations. Every gesture can become musical. Shape your performance with multi-touch, directional gestures, device motion, aftertouch, pitch movement, XY pads, sliders, knobs, and macros. Optional facial controls let head and expression movements influence harmony, modulation, register, and other performance destinations in real time. Performance Modes transform these inputs into coordinated musical systems. Intelligent voice leading keeps chords connected, expressive harmony controls create fluid transitions, and synchronized arpeggiation follows your DAW’s tempo and phase without restarting the pattern. Built-in modes provide focused setups for piano performance, harmony exploration, musical learning, generative flow, and Ableton control, while Custom Mode lets you create your own instrument. Save complete instruments and performance setups in the Layout Library, then switch between them quickly. Discover and install compatible instruments through the midiOS Marketplace, or transfer your own layouts securely between midiOS and the midiOS Bridge. Using the free midiOS Bridge for Mac, connect over USB or Wi-Fi for a fast, authenticated MIDI connection to your computer. midiOS works with MIDI-compatible software and offers deep Ableton Live integration, including clip and scene launching, transport, session navigation, mixer controls, macros, and real-time visual feedback on your iPhone.

Built for live performance, midiOS combines responsive MIDI, intelligent harmony, stable note ownership, fast layout switching, haptic feedback, visual feedback, and automatic reconnection in a workflow designed to keep you focused on making music.
