Magenta is an open-source project that includes a collection of Ableton Live plugins to boost your creative potential with machine learning. It includes plugins like "Continue," "Generate," "Interpolate," "Groove," and "Drumify" to create new melodic patterns, rhythms and drum beats, and to interpolate between different styles. It's free to use, no subscription required, and is designed to encourage a community of artists and musicians to experiment with AI music.
Beat Shaper is another AI music production assistant that can generate beats, basslines, melodies and VST synthesizer presets based on your style. It can generate MIDI, create dynamic melodies and arrange a song. It's in beta testing, but Beat Shaper promises to be fully integrated with digital audio workstations and to let you control the output creatively.
If you want to concentrate on drum patterns, Drumloop AI offers an interactive beat sequencer and an AI tool to create your own drum loops based on your input. It's designed to be easy to use for pros and beginners, with a free trial and royalty-free drum loops you can drop into your DAW to build a song.
