🆓 New From Dusk Audio: Chord Analyzer, FREE Real-Time Chord Detection Plugin

[LinkedMusicians]

PETER’S TAKE: This seems very cool. While it bills itself as “real-time,” I’d be interested in seeing how accurate it is for analyzing MIDI. I have a habit of jamming to old original songs and coming up with new parts and sometimes I have no idea what I played an hour later because it’s improvised. I end up trying to pick apart things by ear — I realize I could look over the MIDI, but if there’s a bunch of improvising, it would be easier just to see the chord flash on the screen, which is the EZKeys works, and I love that, but most plugins don’t have that functionality. I picked up a plugin from Hornet, but it’s not very accurate.

Route MIDI to Chord Analyzer and instantly see what chord you’re playing, its Roman numeral in your chosen key, and its harmonic function. Get intelligent suggestions for what chord to play next, from basic I-IV-V progressions to advanced chromatic mediants and Coltrane changes.

Features
Chord Detection
Recognizes 45 chord types including triads, seventh chords, extended chords (9th, 11th, 13th), altered dominants, sus chords, and power chords. Detects inversions and displays slash notation.

Music Theory Analysis
Set your key (any root, major or minor) and see Roman numeral analysis for every chord. Harmonic function labels (Tonic, Subdominant, Dominant, Borrowed, Chromatic) help you understand the role each chord plays.

Chord Suggestions
Three tiers of suggestions based on your current chord:

Basic — Common progressions (I-IV-V, ii-V-I, vi-IV)
Intermediate — Secondary dominants, borrowed chords, tritone substitutions
Advanced — Chromatic mediants, Neapolitan chords, augmented 6th approaches
Session Recording
Record your chord progressions with timing data and export as JSON for analysis, notation software, or further processing.

Educational Tooltips
Hover over any element to learn about chord qualities, harmonic functions, and why certain progressions work.

For Windows, macOS, and Linux.
