Feedback
Overview
Rift’s feedback processor is incredibly flexible and can create a wide array of sounds, especially when combined with the distortion engine. It is capable of producing tuned melodies, complex stereo delays, distorted feedback, chorus-like modulation effects, and more.
Feedback Bypass
Turn the Feedback 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.
Feedback Mode. Toggle between two different channel modes:
Stereo. Standard stereo mode.
Ping Pong. Feedback patterns that bounce back and forth from left to right.
Frequency Range. Select how the feedback Frequency is mapped
Midi. The Feedback tracks Midi notes sent to Rift Frequency transposes these notes by semitones.
Tune. Set Frequency to specific notes.
Comb. Set Frequency in Hz for comb filter effects.
Free. Set Frequency in milliseconds, covering standard delay ranges.
Sync. Set Frequency to all types of BPM synced values.
Norm. Set Frequency to ”standard” BPM synced values.
Trip. Set Frequency to triplet BPM synced values.
Dot. Set Frequency to dotted BPM synced values.
In general, Tuned ranges are for resonator, flanger, and chorus effects, while Timed ranges are for delay and echo effects.
Feedback Amount
Adjust how much of the signal is fed back into itself. Negative values invert the feedback signal, which is most noticeable with Tuned feedback frequencies.
Feedback Distort
When active, the Feedback is sent through the distortion engine. This will result in a variety of effects depending on which algorithms are selected.
Enabling Feedback Distort can cause the feedback to blow up more easily. Try assigning Follow modulation to Feedback to keep extreme settings under control.
Feedback Spread
Adjust the relative Frequency of the left and right feedback channels to create wide stereo effects. This can be used for detuning in Tuned modes and creating interesting delay patterns in Timed modes. Positive values gradually make the right feedback lower/longer and the left delay higher/shorter. The inverse is true for negative values.
Try setting Spread slightly above or below zero to create a wide stereo image without changing the Feedback Frequency. Alternately, higher Spread settings can be used to create chord effects with a Tuned Frequency Range or interesting stereo patterns with a Timed Frequency Range.
Highpass. Adjust the Feedack Highpass filter. Higher settings help prevent low-frequency build-up.
Lowpass. Adjust the Feedback Lowpass filter. Lower settings create warmer effects, while higher values retain more high frequencies.
Feedback mix. Control the Mix between the distorted signal entering the Feedback module and the feedback’s output.
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!
Frequency Pitch Snap
Off
On
Create musical scales by selecting which notes Frequency will snap to. With all twelve pitch buttons off, any modulation sent to Frequency will move freely between notes. This only affects Frequency in Key and Tune modes.
Toggle Note On. Feedback Frequency will snap to the notes that are toggled On.
Toggle Note Off. Feedback Frequency will Not snap to the notes that are toggled Off.
Lock Scale. When enabled, this will preserve the current selection of notes while changing presets.
Select Preset Scale. Choose from a variety of useful scales for the Pitch Snap.
Pitch Snap Link. Link which notes are selected for both Frequency and Cutoff. This will only have an effect in Midi and Tune modes.
