Atlas Harmonia (VST Plugin)

Atlas Harmonia is a modal chord explorer plugin for music producers and composers. Pick a mode, pick a key, and it instantly shows every diatonic chord available — from simple triads all the way to rich 13th voicings. It also surfaces secondary dominants and modal interchange options, so you can add harmonic color without memorizing theory textbooks. Hear any chord instantly with the built-in piano synth, build progressions with the drag-and-drop builder, then click and drag the MIDI straight into your DAW timeline. Each mode comes with curated progression suggestions for verse, chorus, and bridge sections — perfect for breaking through writer's block or exploring unfamiliar harmonic territory. Works as a VST3 on Windows and macOS, and as an Audio Units plugin on macOS for Logic Pro users. Compatible with Ableton Live, Cubase, FL Studio, Logic Pro, Reaper, Bitwig, and more.
