Ableton's official Learn Live series walks through Roar's feedback controls, showing how each parameter shapes the character of feedback-driven distortion. Feedback amount feeds the device's output back into its input, while phase inversion shifts the tonal quality of the effect.
The feedback gate is a key detail: when enabled, feedback dissipates quickly after the signal stops. Disable it and the feedback rings out freely, which can turn a subtle effect into something much more dramatic.
The frequency and bandwidth of the feedback filter let you focus the feedback on a specific spectral range rather than letting it spread across the full signal. Adjusting feedback time gives you manual control over the repeat interval.
Switching from Time to Sync mode locks feedback timing to the session clock, with options for straight, triplet, and dotted rhythmic values. You can also tune the feedback to a specific note, which opens up pitched, resonant textures that sit in a musical relationship with your arrangement.
