LUMA: Chords in Any Key

Pick a key, tap a pad and play a whole chord that fits. Slide between chords, shape them on the joypad, add an arp and drums, then export your take as audio or MIDI.

LUMA is a chord synth for iPhone. Pick a key, tap one of seven pads, and play a whole chord that fits. No wrong notes, no theory needed: just progressions under your fingers.

PLAY • Seven chord pads built from your key, so every chord belongs • Slide between pads to move from chord to chord • Chord modes: diatonic, open, jazz and simple voicings • Synth voices including saw, pad, drone and organ

SHAPE • Joypad: one hand on filter, pitch bend and rhythmic pulse • Arpeggiator with rates, patterns and octave range • Drum loops and a metronome to play along with

RECORD AND CONNECT • REC captures takes, both the audio and the chords • Export takes as audio or MIDI files to finish in your DAW • MIDI OUT over USB and Wi-Fi to hardware synths and DAWs • Play from a Bluetooth game controller

Made for producers, audio engineers and hobbyists who'd rather play chords than look them up.
