Ableton's Connect tool, introduced in Live 12, generates new MIDI notes that fill the gaps between existing chord notes in a clip. This is a focused walkthrough of its five main parameters: Rate sets the minimum length of generated notes, Density controls how many notes are added relative to available empty space, and Spread widens or narrows the pitch range of the new notes around the originals.
The Apply button regenerates the results each time, letting you audition multiple variations quickly. The Tie knob smooths out dense patterns by merging rapid note successions into single tied notes, which can tame overly busy output and give the generated material a more musical feel.
