Harmonaut™ is a chord instrument you play by feel. Press a key and hear a rich chord, voice-led smoothly from the last one, no theory needed. Build a progression, shape its mood, and export it as MIDI for your track. Two faders let you shape the mood as you play: more tension or less, brighter or darker, even major to minor. Chase a moody electronic progression, a warm lo-fi loop, a jazzy turn, a cinematic swell, or a simple pop hook. It all comes from your intent, not from naming chords. HOW IT PLAYS • Tension that actually resolves: chords that lean, pull home, and land, so your progression goes somewhere instead of just floating • Every one of the twelve keys is in play: reach past the obvious chords for richer, more surprising color, and it still sounds right • Build a whole progression, not just four chords: every chord you play lands in your trail, ready to reorder or duplicate to try new versions in seconds • Pick up right where you left off: your ideas are saved for you TAKE IT TO YOUR TRACK • Export any progression as a MIDI file and drop it into BandLab, GarageBand, or any DAW that opens MIDI, then play it through any instrument you like • Export to iReal Pro format to keep a chord chart or practice over the changes • Harmonaut Pro unlocks MIDI export, iReal Pro export, and unlimited saved progressions IT SOUNDS GOOD FOR A REASON Every chord is voice-led from the one before it, live, as you play: the notes move the shortest way, so a progression flows instead of jumping around. That's the finished feeling you hear in the songs you love. Push Intensity and the voicings open up: lush 9ths, bright 13ths, and altered dominants like G7#9b13, the colors session keyboard players reach for. And Harmonaut names every chord the way musicians actually write it, like Ebmaj7, so you can hand your progression to a session player, a bandmate, or a producer and they'll play it back exactly, first time. No box to buy, nothing to charge, no menus to dig through. It's already in your pocket. Whether it's your first progression or a sound you can hear but can't name, Harmonaut meets you where you are.
