Shifter

---

Overview

Shifter provides stereo frequency shifting, ring modulation, and amplitude modulation with feedback and FM. It can create inharmonic, robotic effects, distinctive harmonic distortion, barber-pole phasing, auto-pan, and more.

1. Effect Dropdown

The Effect Dropdown lets you remove or swap the effect and load or save sub-presets. See Shared Settings for dropdown options and detailed descriptions.

2. Shifter Mode

Freq Shift. Applies linear frequency shifting to the signal. At higher shift amounts, it moves the sound up or down in frequency but also alters harmonic relationships, often producing inharmonic results. At lower amounts, mixing with the dry signal can create barber-pole phasing.

Ring Mod. Multiplies the input signal by a sine oscillator, generating sidebands above and below the original frequencies. At higher frequencies, this produces complex, often inharmonic tones useful for metallic or bell-like effects. At lower frequencies, it can produce tremolo or auto-panning, though amplitude modulation is often better suited for these tasks.

Amp Mod. Modulates the signal’s amplitude with an internal oscillator, generating sidebands above and below the original frequencies while preserving more of the original input than ring modulation. At higher frequencies, it produces rich harmonic effects. At lower frequencies, it can create tremolo or auto-panning.

3. Shifter Display

The Shifter Display visualizes stereo frequency shifting, phase, and feedback as you adjust parameters in real time, providing a clear view of changes.

4. Shifter Controls

Frequency. Sets the internal modulation oscillator frequency. Higher values (positive or negative) produce more intense shifting and harmonic effects, while values near zero produce slower phaser, tremolo, and auto-pan effects.

Frequency BPM Sync. Click the button to the right of Frequency to toggle between frequency and BPM-synced values.

Feedback. Feeds a portion of the output signal back into the input path. It increases resonance, intensifies harmonic distortion, and can lead to chaotic, noisy textures at high settings.

FM. Sets how much the input signal frequency-modulates the internal oscillator, introducing additional harmonic complexity. Lower values produce saturation-like sounds, while higher values can result in full-on harmonic destruction.

Phase. Offsets the stereo phase of the internal oscillator. While it can always be used to widen the stereo image, the effect is most pronounced at lower Frequency settings, where it can create stereo phasing and auto-pan effects.

5. Mix Controls

In. Sets the level of the wet signal path before processing. Use it to drive the effect harder when using FM.

Out. Sets the final level after processing and dry/wet mixing.

Mix. Blends the unprocessed (dry) and processed (wet) signals. In Freq Shift mode, set this to 50% to produce a barber-pole phasing effect at low Frequencies.
