This walkthrough shows how Live 12.2's Spectral Resonator turns a plain audio loop into something melodic by locking it to the current scale. Applied to a vocal chop, the effect quantizes its harmonics so the sample starts sounding like it's playing chords instead of just resonating randomly.
Switching Frequency Control to Scale Degrees lets you play the resonator's pitch like an instrument, snapping every note to the key you're working in. From there, stretch and harmonic count shape the tone, with fewer harmonics acting like a low-pass filter on the resulting sound.
Widening with Unison and extending Decay thickens the effect into a lush, sustained texture that sits well underneath other elements, like layered synth stabs. The core idea: scale-aware resonance can turn almost any sample into a tuned, chord-like layer without touching a sampler or synth.
