Harmonybeam is a Max for Live chord progression plugin for producers working in Ableton Live. It supports entering and editing chord notation, generating progressions from genre-based algorithms, and getting context-aware chord suggestions and substitutions. Voicing styles, inversions and automatic voice leading provide ways to shape the harmony, while rhythm presets and a custom pattern editor add control over its rhythmic feel. It is aimed at Ableton users who want harmony assistance inside their MIDI workflow rather than a standalone generator. The product details specify no AI features, so its category label should not be taken as a claim that it uses AI.

Its strongest fit is the connection between harmony generation and Ableton’s clip workflow. Harmonybeam can synchronize changes directly to MIDI clips in Session and Arrangement views, and a Bass Split option routes bass to a separate MIDI track. More than 40 rhythm presets, configurable MIDI keyboard and CC controls, and chord editing round out the workflow. It supports Ableton Live 10 or newer on macOS and Windows; Arrangement View clip sync requires Live 11 or newer. The stated integrations are Ableton Live and Max for Live, so producers seeking a plugin for another DAW should look elsewhere.

According to the published plan, Harmonybeam costs $24 as a one-time purchase, with free updates for life; the license key is sent by email after an instant download. There is no subscription described. That makes the price straightforward for someone already using a compatible Ableton setup, but the platform restriction is decisive: the vendor says the product is currently available only for Ableton Live, and a VST version is only being considered. Producers seeking cross-DAW use or a VST should choose an alternative. Those comfortable with Max for Live and Live’s version requirements may find its combination of progression generation, voice leading, rhythm controls and clip sync a focused fit.
