This walkthrough shows Ableton's Spectral Resonator turning a plain drum break into something melodic. Feeding a drum loop through the device makes every hit resonate at the same pitch, so the break starts sounding like a single tuned note rather than a rhythmic pattern.
The Frequency dial controls that pitch directly, with a musical-icon toggle to switch from raw frequency values to semitones for easier tuning by ear.
Switching Spectral Resonator's mode from Internal to MIDI hands pitch control over to a keyboard instead of the dial. Arming a MIDI input track lets the resonator track played notes in real time, turning the drum loop into a genuinely playable instrument.
From there, Glide adds pitch-bend style slides between notes, the PB slider sets how far a hardware pitch-bend wheel pushes the tuning, and MIDI Gate mutes the resonated signal whenever no notes are held, so the drums only sound tonal while you're actively playing them.
