Bad Snacks demonstrates how to use Ableton's built-in rhythm generator to build a bassline from scratch, without playing a single note manually. After generating a rhythmic pattern on a root note, she selects the first half and transposes it up to match a chord change, showing how a simple arrow-key edit can keep a bassline locked to the harmony.
The second idea here is velocity as an accent tool. The rhythm generator assigns varying velocity levels to each note automatically, and those differences are what give the pattern its feel. Higher velocity hits land on the downbeats, softer ones fill in around them, creating a natural groove without any manual tweaking.
