Melodai

Melodai is a desktop-class DAW for iPhone, iPad, and Mac: multi-track editing, instruments you can play, a full FX rack, and on-device AI for jam, stems, and sheet scan. The mix stays on your device. RECORD AND ARRANGE Build a song on a real timeline. Audio, voice, loops, and MIDI tracks live in one project. Move, split, duplicate, and snap clips. Record from the mic or into the instrument you have open, with count-in and overdub. Undo walks a change back. PLAY THE INSTRUMENTS Select a track and the dock becomes the instrument: keys, drums, guitar, bass, 808, synth, violin, saxophone, or Guzheng. Tap, play, and record MIDI, then edit notes in the piano roll. MIX AND SHAPE A studio FX rack on every track and on the master: parametric EQ, 10-band EQ, compressor, limiter, reverb, delay, chorus, flanger, phaser, tremolo, distortion, and pitch. Drop in loops from a bundled library filed by drums, bass, keys, guitar, synth, strings, vocals, and genre. Clean a take with on-device noise reduction. ON-DEVICE AI Jam: hold notes, pick a style — Lo-Fi, Dark Jazz, Trap, Orchestral, and more — and generate a take on Apple silicon. Prompt Mixer: blend style terms on faders and generate into the mix you dialled in. Stems: split a song into bass, drums, other, and vocal, then open it as a four-track session. Sheet scan: photograph a piano score and open MIDI you can play and edit. MIDI import: drop a .mid file and it becomes tracks and notes, not a dead bounce. Jam, stems, sheet scan, and noise reduction run with Core ML on your device. Your recordings are not uploaded to finish an edit. Optional text-to-arrangement compose sends only a prompt, never your audio. EXPORT Share MP3 or AAC. Bounce lossless WAV, AIFF, or 32-bit float CAF when the file has to leave as audio. iPhone, iPad, and Mac. No ads, no tracking, no account. MELODAI PRO You can build a song for free. Pro unlocks the full instrument set, piano roll, Pro loops, Jam, Prompt Mixer, stem split, EQ, noise reduction, and lossless export. If a session uses those tools, Pro is required to export.
