Overview
| Name | Version: | Harmony Engine 1.0 |
| Author: | NA7AN |
| Device Type: | MIDI Effect |
| Description: | Chords, bass and melody from one harmonic idea, written into your Set as editable MIDI clips. 100% offline, Ableton Live 12. Not a live MIDI effect. Nothing to freeze, resample or record — press GENERATE and the clips are in your tracks. WHAT IT WRITES Three layers, derived from the same harmony so they actually fit together: chords, a bassline and a melody. They arrive as three named MIDI clips on three tracks — HE-Chords, HE-Bass, HE-Melody — as real notes you can edit, chop or throw half away. Session, Arrangement, or both. Your choice, one button. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ LOCK — why this is a writing tool and not a slot machine Every layer has its own GEN, LOCK and VAR. • Like the chords, hate the bass? Lock the chords and regenerate the bass. It rebuilds itself around harmony that is not allowed to move. • Lock that too and push the melody until it sings. • VAR gives you a near neighbour instead of a fresh idea — the key, the length and most of the harmonic skeleton survive. • Click any chord card to reshape that chord in place. It stays on its scale degree and survives every regeneration after that. Generate, keep what worked, reroll the rest. That loop is how an idea turns into a track. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ IT FOLLOWS YOUR KEY Set a Key and Scale in Live 12's control bar and the device follows it. Change the Set's key and the device is already there. Or switch to DEVICE and pick from 16 scales yourself: Major, Minor, the five remaining modes, Harmonic Minor, Melodic Minor, Harmonic Major, Phrygian Dominant, Lydian Dominant, both pentatonics, Minor Blues, Whole Tone. Chord symbols are spelled for the key you are actually in. In C Dorian you get Bb, not A#. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 13 STYLES, 10 MOODS Melodic Techno · Progressive House · Melodic House · Deep House · Organic House · Afro House · Indie Dance · Tech House · Minimal Deep Tech · Minimal House · Ambient · Electronica · Trance Each style carries its own harmonic vocabulary — which chords it reaches for, how far it moves, how much tension it holds, how the bass sits. Tech House leans on triads and repetition. Ambient lives on sus chords and four-bar changes. Trance pulls hard towards the dominant. Ten moods bend a style rather than replacing it: Dark, Emotional, Hypnotic, Euphoric, Dreamy, Warm, Tense, Mysterious, Uplifting, Melancholic. The same mood reads differently on every style. Five presets to start from: Dark Hypnotic, Emotional Lift, Afro Deep, Deep Warm, Melodic Club. Section length: 1, 2, 4, 8 or 16 bars. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ FOUR MACROS • TENSION — how unstable the harmony may get: dissonance, borrowed chords, chords from outside the key • COMPLEXITY — triads and suspensions at the bottom, 7ths and 9ths in the middle, 11ths and 13ths at the top • MOVEMENT — how far the harmony travels and how many chords it uses • DENSITY — how busy the bass and melody are All four are real Live parameters: they appear in the automation list and take MIDI mapping. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ TESTED, NOT JUST TUNED Every build runs 296 automated tests plus two audit passes over thousands of generated progressions — leading tones resolving upward, sevenths resolving down, parallel fifths and octaves, augmented seconds, chord symbols spelled against the right key signature, every note inside the scale, and whether each knob on the panel actually changes the music it claims to. That is why the output sounds like a part rather than a random chord generator. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ REPRODUCIBLE The same seed with the same settings always gives the same music. Your Set stores a handful of numbers rather than a blob of notes and regenerates the identical material on load — locked layers included. Drag SEED to scrub through ideas. Hit the dice for a fresh one. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT'S IN THE DOWNLOAD • Harmony Engine.amxd — the track device (MIDI Effect) • Harmony Engine Generator.amxd — companion MIDI Tool for Live 12's Generate tab • User manual, and install instructions in English and Portuguese ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ REQUIREMENTS • Ableton Live 12 with Max for Live • Windows or macOS Live 12 Intro and Lite cannot run Max for Live devices.
