Filter

Overview

Rift’s filter is useful for adding color, movement, and stereo effects or simply warming up a distorted signal.

1. Filter Bypass. Turn the Filter module on or off. This is useful for A-B’ing the effect or reducing Rift’s CPU load when the module is not needed.

1. Filter Routing. Choose if the filter comes before or after both the distortion and feedback.

Pre: Filter ⟶ Distortion ⟶ Feedbackpre is ideal for more distorted effects.

Post: Distortion ⟶ Feedback ⟶ Filterpost is great for filtering rich harmonics from the distortion and feedback.

1. Filter Type. Select filter type:

• Basic: Standard 24dB filters.

• Morph: Filters that smoothly morph between different types.

• Peaking: Filters that use peaks and notches to create formant and phaser-like effects.

• Harmonic: Filters based on the harmonic series, ideal for accenting or reducing specific harmonics in a sound. Especially effective when the filter is set to Pre.

1. Cutoff. Controls the Filter frequency in Hz or Tuned notes

Cutoff Range

Select how the filter Cutoff is mapped:

• MIDI. The filter’s cutoff tracks MIDI notes sent to Rift, and Cutoff transposes these notes by semitones.

• HZ. Cutoff is set to standard Hz values.

• Tune. Cutoff is set to specific note values.

1. Resonance. Set the amount of Filter Resonance.

1. Morph. Morph between the internal Filter settings. This can create different effects depending on which Filter is selected.

1. Filter Spread. Adjust the relative Cutoff of the left and right channels to create wide stereo effects. Positive values gradually make the right filter higher, and the left filter lower. The inverse is true for negative values.

1. Filter Mix. Control the mix between the signal entering the Filter and the wet filtered mix.

1. Filter Amp Mod. Add audio rate amplitude modulation that follows the filter’s Cutoff frequency.

This is useful for creating extra harmonics and tonal content that can sound similar to frequency modulation.

Try combing Amp Mod with Tune and MIDI modes to create melodic harmonics with the Cutoff

Pitch Snap. is a useful tool for quantizing the Cutoff to specific notes and scales. When combined with modulating Cutoff, you can create melodies with Rift!

1. Cutoff Pitch Snap. Create musical scales by selecting which notes Cutoff will snap to. With all twelve pitch buttons off, any modulation sent to Cutoff will move freely between notes. This only affects Cutoff in MIDI and Tune modes.

Toggle Note ON. Cutoff will snap to the notes that are toggled ON.

Toggle Note OFF. Cutoff will NOT snap to the notes that are toggled OFF.

1. Select Preset Scale. Choose from a variety of useful scales for the Pitch Snap

1. Lock Scale. When enabled, this will preserve the current selection of notes while changing presets.

1. Pitch Snap Link. Link which notes are selected for both Frequency and Cutoff. This will only have an effect in MIDI and Tune modes.
