HouseEngine is a plug-in that generates new melodies, basslines, hooks, and riffs from your MIDI chord progressions automatically.
The concept is simple:
Simply download the installer and install the plug-in on your system. Then open your DAW and add HouseEngine to a track.
HouseEngine comes with a selection of factory chord progressions. But you can also import your own MIDI chord progressions.
Your MIDI file should look like this:
If your chord progression doesn't contain dedicated bass notes (the lowest notes of the chords), then HouseEngine will guess some good bass notes for you.
Listen to the chord progression to check if everything sounds good. You can right-click on a chord to change the bass note if needed.
The key/scale setting will only affect some of the patches. It does not transpose the chords when you change it. The key/scale setting is important for HouseEngine to take the musical context of the progression into account. In most cases, the plug-in should guess the correct scale. However, if it detected the wrong scale, you can change it manually here.
As soon as you import a chord progression, HouseEngine generates a list of presets for you. Select a preset, then press play in your DAW for a preview.
On the left side, you can find a search bar and a tag browser. Click on a tag to see only presets with that tag. You can select multiple tags as well.
You can find a MIDI preview area on the right side of each preset. It displays the notes to give you a quick overview of the generated notes.
You can drag and drop this MIDI area to your DAW to export the preset as a standard MIDI file. If your DAW doesn't support drag and drop, you can drag the MIDI file to an open Explorer window (Windows) or Finder window (macOS).
Not all presets will have the same length as your original chord progression. Some might be longer because the preset needs more time for melodic changes, modulations, or embellishments. The generated output will have the same meter as the original chord progression.
If you use the VST version, you can route the generated notes to another synth via MIDI.

Attention: The AU version doesn't support this feature. AU components can either operate as an audio plug-in or as a MIDI plug-in, but not as both.
The demo version generates a small melody every few seconds that is only audible in the MIDI output.
