SongEngine is a music plug-in for creating chord progressions and generating basslines, phrases, and melodies to fit them. Users can build chords with Chord Pads, import MIDI progressions, or generate progressions in the plug-in. Its free core includes 60+ presets for basslines, arpeggios, phrases, and melodies. Live Mode converts MIDI chords from a keyboard or DAW into new MIDI phrases in real time. Generated parts can be dragged into a DAW as standard MIDI files; an optional MassExporter can save hundreds of phrases to a computer folder. SongEngine runs as a VST2, VST3, or AU plug-in, so it needs a compatible host such as FL Studio or Ableton Live. It supports Windows 7, 8, 10, and 11 in 64-bit, plus macOS 10.13 and later on 64-bit Intel or Apple Silicon processors. There is no official Linux build, though the manual says users have reported using Wine. The maker says SongEngine is not an AI tool and that its algorithms were made by human musicians. Generated MIDI files may be used in commercial releases.
