MIDI chord generator plugin workflow for Logic Pro.

If you want a chord generator workflow in Logic Pro, Harmonimo now has a direct path: load the AU plug-in in Logic, trigger full chords from single notes, and keep the rest of the session inside Logic instead of building an external routing chain first.

Best for Chord writing, one-handed harmony, and controller-led performance
Optional route Standalone routing is still there for wider MIDI setups

Direct support inside Logic Pro

The setup is simpler now.

Harmonimo now supports Logic Pro directly through AU, so the normal starting point is a native plug-in workflow inside the project. That keeps chord generation, instrument choice, recording, and arrangement decisions in one place instead of splitting them across separate apps.

In practice, that means Logic users can load Harmonimo, play a note, shape voicings and extensions, and keep moving without setting up a virtual MIDI bus first.

  • No virtual MIDI bus required for standard Logic sessions
  • A better fit for writing, recording, and arrangement in one project

Where it fits in a Logic workflow

The Logic advantage is keeping the harmony work close to the session.

Logic users usually want quick progression sketching, one-handed harmony, and controller access without breaking the flow of the arrangement. Harmonimo fits well there because you can keep your keys, synths, and arrangement decisions inside the same session while the plug-in handles the harmonic translation.

That is especially useful when you want to test extensions, inversions, strum, and spread against the same patch. You can move between cleaner pop voicings and richer neo-soul or jazz colors without rebuilding the MIDI by hand every time.

  • Progression sketching without note-by-note chord entry
  • One-handed chords while the other hand handles melody or automation
  • Controller-friendly harmony shaping inside Logic

When standalone routing still makes sense

The direct AU route should be the default, but it is not the only option.

Standalone routing is still useful when you want a separate performance surface, an external synth path, or a more modular multi-app MIDI setup. Harmonimo Standalone plus a virtual MIDI bus remains a valid route when you deliberately want that flexibility.

For most Logic users, though, the native AU path is the cleaner start. Use virtual MIDI only when you intentionally want to split the harmony engine away from the main project.

  • Use AU directly for standard Logic sessions
  • Use standalone when you want external or cross-app MIDI routing

For most Logic setups, start with the direct AU workflow. Reach for virtual MIDI when you intentionally want a wider routing rig.
