Ableton/Live/UG/29 Audio Effect Reference/36 Spectral Resonator/02 Frequency Section

- Internal mode: Freq sets the pitch in Hz or as a note (Frequency Control Mode buttons). With Use Current Scale, it follows the clip's scale and Freq becomes SD Shift, transposing by scale degrees; with no scale active it uses the chromatic scale.
- MIDI mode: notes set the pitch; Transp. shifts them ±48 semitones, or becomes SD Shift (±28 scale degrees) with scale awareness.
- With a tuning system, Freq and Transp. use the tuning's note indices.
- Stretch — spacing of the harmonics; below 0% closer, above 0% wider. At 100% only odd harmonics remain, a square-wave sound.
- Shift — transposes the input's spectrum ±48 semitones before it reaches the resonator
- Decay — how long the resonances last
- HF Damp / LF Damp — damping of high and low partials; the ranges move with the current pitch
