Chordinator uses the principles of tonal step theory — so instead of remembering which notes belong to which scale, the software does the math for you in real time.
Select the key and scale. Chordinator knows which chords belong there and builds them automatically from the step theory rules. No voicing knowledge required.
The left side of your MIDI keyboard maps to the 7 chord steps (I–VII). One finger triggers the complete chord with your chosen voicing, extension and inversion.
The right side transposes automatically to the current chord's scale. Whatever you play sounds musical — even if you've never improvised before.
One keystroke triggers a complete chord — root, third, fifth, seventh and extensions — voiced and inverted exactly as you set it. The 3-zone keyboard split: Key Select · Chord Section · Solo Section.
Core featureThe solo zone is continuously remapped to the current chord's scale. You always play C–D–E–F–G–A–B in C major position — Chordinator shifts every note to the correct pitch in real time.
Unique to ChordinatorThe black keys in the chord zone act as real-time modifiers — like a computer shift key. Press before the chord to change its colour on the fly:
Extensions (7th, 9th, 11th, 13th), alterations (♭9, ♯9, ♯11, ♭13), inversions up to 9 degrees, drop voicings, shell voicings, Sus4 mode, Tritone Sub — all parameters, advanced harmony without advanced knowledge.
Power userEliminates robotic block chords. 5 strum patterns with adjustable delay (0–2000ms) — from subtle 20ms rolls to slow harp strums:
Chordinator sends four dedicated MIDI channels simultaneously: Ch 2 Bass · Ch 3 Chord · Ch 4 Solo · Ch 5 Arp. Each voice goes to its own track in your DAW for full mixing and sound design control.
Studio readyAuto Inversion crawls the chord up and down through inversions at every keystroke. Auto Spread cycles between Triad → 7th → 9th → 11th. Together they generate fresh harmonic colour on every chord press without touching a slider.
VariationEvery parameter in Chordinator is mappable to any MIDI CC. Hit Learn, move your controller knob, done. A SHIFT layer doubles the addressable range — ideal for compact controllers with few sliders. Settings persist on restart.
Controller friendlyNo DAW required. Chordinator includes a General MIDI Soundfont player with separate instruments for Bass, Chord and Solo channels. Great for practising, composing and demoing ideas — plug in your MIDI keyboard and play immediately.
StandaloneGenerates arpeggios and walking bass patterns from the current chord automatically. Direction, rhythm and style are all adjustable — from simple root-fifth patterns to jazz-style bebop lines. Used by the Humanizer as its foundation for time-based note sequencing.
CompositionPlay any track through Chordinator. It analyses the audio in real time, detects the key, sets it automatically and shows which chord step is active — so you can play along to your favourite songs immediately.
Play-alongSus4 mode replaces thirds with suspended fourths for that floating, unresolved sound (Pinball Wizard, Breathe, Message in a Bottle). Tritone Substitution swaps the V dominant chord with a chord a tritone away — essential for jazz and bossa nova.
Advanced harmonyAccordion Relative Notation — sheet music always in C major regardless of actual key. No sharps, no flats, no bass clef. Roman numerals for chords, arabic numbers for melody notes. Music you can actually read immediately.
Beginner-friendlyTraditional notation forces you to read different clefs, sharps and flats depending on the key. ARN eliminates this — everything is always written in C major, in the treble clef. The software handles the actual transposition. You just read.
Chordinator transposes everything to A major in real time. You play C–F–G–C.
Watch Chordinator in a real session — chord generation, solo transposition and ARN notation all live at once.
All exercises are written in ARN — always in C major, regardless of the actual key. Start with single root notes and work up to full arpeggios and licks. Chordinator handles every transposition in real time.
"Music is logic, not magic.— The idea behind Chordinator
Chordinator makes the logic visible."
Chordinator sends each musical voice on its own MIDI channel — route them independently in any DAW for mixing, sound design or recording.
Every parameter in Chordinator is mappable to a hardware knob or pad. Select a parameter → press Learn → move your controller. A SHIFT layer doubles the addressable range for compact controllers. All assignments are saved and reload automatically.
