CadenceA free authoring companion for Ableton Live. Cadence sees your set through its own Live link, hears the key, suggests chord progressions by style, and writes chords, arps, drum fills, breaks, risers and smoothing envelopes straight into session slots, after you have heard them. Add your Anthropic key and Claude sits inside the plug-in with the same tools, so you can ask for a darker progression and a fill into the drop in one sentence.
Cadence is built for the moments when you know what you want and would rather hear it than build it.
Detect listens to the track and names the key. The Harmony card lays out every chord in it, and the progressions list is filtered to the ones that suit that scale and your style.
Look at: The Key card, then Harmony: the chord grid and the progressions list.
Yes. Click a chord to hear it. Press Hear on a progression or a generated clip and it plays once through the target track's instrument from a scratch clip that is removed afterwards.
Look at: Hear on Harmony and Generate; the piano-roll preview above it.
With your Anthropic key in Settings, ask the assistant for a darker progression and a fill into the drop. It reads the set, writes both, and tells you which slots they went to.
Look at: The Assistant card; every tool call shows as a row.
Click any screen for full size. All at 1180 by 980, the default window.
