VocalShift

A high quality vocal harmonizer from the company that invented the term, VocalShift is Eventide’s best offering yet for vocal focused effects. 3 voices with independent pitch and formant shifting, key/scale quantization, detune, delay lines and panning controls. The perfect tool for modern vocal production.

  • Mix: Wet/Dry mixer.

  • Root: Sets the root for the Scale parameter.

  • Scale: Set the Scale that determines the pitch shifted intervals.

  • Shift A/B/C: Pitch shift interval.

  • Formant A/B/C: Formant shift amount. Positive values will make the voice sound more chipmunky, negative values will make the voice sound more throaty. Leaving this control at 0 will preserve the formants and give a more natural sound when changing the Shift parameter.

  • Formant Link: Automatically stretches or compresses the vocal formants in proportion to the pitch shift interval. Positive values will make the voice sound more throaty when pitching down and more chipmunky when shifting up. Negative values invert this relationship. Larger positive or negative values produce a more pronounced effect. A value of 0 preserves the natural formants of the voice (they are unaltered).

  • Gain A/B/C: Voice level.

  • Delay A/B/C: Delay time in ms or Tempo Synced.

  • Feedback A/B/C: Feedback amount.

  • Pan A/B/C: Stereo position (-50: left, 0: center, 50: right).

  • Detune: Applies equal detuning up and down to Voice B & C from 0 to 50c. 0 to -50c applies opposite detuning.

  • Tuning Speed: Adjust the speed of pitch shifting from snappy, hard tuned quantization to more subtle pitch correction. Note that tuning speed is applied whether quantization is on/off, and is an important parameter to tuning how the algorithms processed the vocal signal. 0 to 500ms.

  • Quant On/Off: Quantize the input shift amount to values determined by the Root/Scale parameters. Can be used for natural pitch correction or popular quantized vocal shifting techniques.

  • Quant Error: Allows small pitch variations not to be quantized. Useful for vocals with vibrato when quantization is on. 0 to 50c.

  • Latency Mode: Low/High - Higher latency may result in improved performance with a tradeoff of more noticeable latency. The high latency setting is recommended when using extreme formant settings. Low introduces ~25ms of latency, while High introduces ~50ms of latency.

  • Glide A/B/C: Pitch shift interval for glide performance control.

  • Rise: Rise time for glide.

  • Fall: Fall time for glide.

  • Hold: Determines which voices are affected when the Hold Performance control is activated (see below).

  • Solo A/B/C: Solos the chosen voice for fine-tuning.

Performance Parameters:

  • Root learn: Pressing the footswitch momentarily analyzes the note currently being sung, and updates the Root control (see above) accordingly.

  • Glide: Pitch shift to the glide interval.

  • Glide (M): Momentary pitch shift to the glide interval.

  • Hold (M): Momentary control. Holds the pitch of the selected voices at their current value (these voices are set in the Parameters menu). Hold is different from a “freeze” — the held voices will still follow your articulations like vibrato, volume, etc. Use Hold to create drones and/or breaks from parallel harmony.

  • Hold: Same as above, but latching.

VocalShiftMIDI

A four voice version of our VocalShift algorithm with MIDI control of the pitch shift values. Great for playing vocal harmonies and chord stacks, pitch correction using a MIDI roll, creating pads and textures, and more. A unison voice replaces the dry signal so you can apply quantization and formant manipulation to your voice alongside 4-part harmonies.

Note: Be sure to hook up a midi device (either through MIDI DIN or USB and set the correct channel)

  • Unison Mix: Mixes in the a unison copy of the dry signal, 100% is entirely the unison signal. Note that there is no true dry signal, but your unison voice will sound more natural with quantization off and higher tuning speeds.

  • Unison Formant: Shift the formants of the unison voice from -600 to 600 c without adjusting the pitch.

  • Tuning Speed: Adjust the speed of pitch shifting from snappy, hard tuned quantization to more subtle pitch correction. 0 to 500ms.

  • Gate: Controls the threshold of the noise gate.

  • Gate Attack: Sets the attack time for the noise gate.

  • Gate Release: Sets the release time for the noise gate.

  • Vibe Rate: The rate of the vibrato applied to the MIDI pitch shifted voices. 0 to 8 Hz.

  • Vibe Depth: The depth of the vibrato applied to the MIDI pitch shifted voices. 0 to 50 c.

  • Vibe Slew: The time it takes before vibrato is applied. 0 to 2000 ms.

  • Glide: Sets the slew time between note changes for each voice. 0 to 5000 octaves per millisecond.

  • Delay: Global Delay time for all voices in ms or Tempo Synced.

  • Feedback: Feedback amount for the delay line.

  • Formant Link: Automatically stretches or compresses the vocal formants in proportion to the pitch shift interval. Positive values will make the voice sound more throaty when pitching down and more chipmunky when shifting up. Negative values invert this relationship. Larger positive or negative values produce a more pronounced effect. A value of 0 preserves the natural formants of the voice (they are unaltered).

  • Spread: Narrow / Medium / Wide. Pans every other voice left or right.

  • Attack: Envelope attack time of the pitch shifted voice. 0 to 3000 ms.

  • Release: Envelope release time of the pitch shifted voice. 0 to 3000 ms.

  • Hold: Off will only output pitch shifted audio while an incoming MIDI note is ON. On will ignore MIDI note OFF and hold the value of the incoming MIDI note until it receives another MIDI note. Attack/Release times do not apply when Sustain is latching.

  • Velocity Sens: Adjusts the sensitivity of incoming MIDI velocity data. At 100, MIDI velocity messages are passed thru unchanged. At 0, MIDI velocity will be ignored and the pitch shifted voices will always play at full volume. At 50, the minimum velocity value would be 64. Use this control if you are unable to adjust the velocity curve on your MIDI controller.

  • Bend Range: Adjust the range of the MIDI pitch bend input.

  • Auto EQ: Boosts both low and high frequencies which often sound quieter after pitch shifting. This can help the pitch shifted voices sit better in the mix.

  • Latency Mode: Low/High - Higher latency may result in improved performance with a tradeoff of more noticeable latency. The high latency setting is recommended when using extreme formant settings. Low introduces ~25 ms of latency, while High introduces ~50 ms of latency.

Perform Parameters:

  • Root learn: Pressing the footswitch momentarily analyzes the note currently being sung, and updates the Root control (see above) accordingly.

  • Freeze: Freezes the input signal, allowing you to create pad effects and shift them using MIDI note input.

  • Freeze (M): Momentarily freezes the input signal, allowing you to create pad effects and shift them using MIDI note input.

VocalTune

A stripped down version of our VocalShift algorithm, designed for vocal correction and hard tune effects. An EQ and compressor round out this algorithm to give you all the tools you need to polish up a vocal track or cut through the mix in a live setting.

  • Root: Sets the root for the Scale parameter.

  • Scale: Set the Scale that determines the intervals that the vocals will be quantized to.

  • Tuning Reference: Set the reference point for the key/scale quantization.

  • Quant Error: Allows small pitch variations to not be quantized. Useful for vocals with vibrato when quantization is on. 0 to 50 c.

  • Formant: Shift the formants from -600 to 600 c without adjusting the pitch.

  • Tuning Speed: Adjust the speed of quantization from snappy, robotic sounding quantization to more subtle pitch correction. 0 to 500 ms.

  • Gain: Compressor makeup gain, -16 to +12 dB.

  • Gate: Threshold of noise gate.

Quadravox+

A 4-voice vocal harmonizer inspired by the Quadravox algorithm, aimed at creative delay and arpeggio style effects. A unison voice replaces the dry signal so you can apply quantization and formant manipulation to your voice alongside 4-part harmonies.

  • Unison Mix: Mixes in the a unison copy of the dry signal, 100% is entirely the unison signal. Note that there is no true dry signal, but your unison voice will sound more natural with quantization off and higher tuning speeds.

  • Unison Formant: Shift the formants of the unison voice from -600 to 600 c without adjusting the pitch.

  • Key: Selects the key.

  • Scale: Selects the scale.

  • Quantization: Quantizes the notes that are not in the selected key scale to fit within the selected key and scale.

  • Formant Link: Automatically stretches or compresses the vocal formants in proportion to the pitch shift interval. Positive values will make the voice sound more throaty when pitching down and more chipmunky when shifting up. Negative values invert this relationship. Larger positive or negative values produce a more pronounced effect. A value of 0 preserves the natural formants of the voice (they are unaltered)

  • Pitch Mix: Controls the ratio of level Pitch A+C to Pitch B+D. With the knob set full counter-clockwise, PitchA + PitchC are set to equal level. Full clock-wise, sets Pitch B + Pitch D to equal levels. The ratio of level of Pitch A to Pitch C and of Pitch B to Pitch D are fixed at equal levels and cannot be changed.

  • Shift A/B/C/D: Selects the harmonic interval (pitch shift) for the Pitch. Set to minimum to turn any voice OFF.

  • Delay: The four delays are not independently variable. Instead, they are staggered with A having the shortest delay, B longer than A, C longer than B and D the longest. The Delay control is used to set the last delay. With Tempo OFF, delay is displayed in ms. With Tempo Sync ON, delay can be sync’d to the tempo and is displayed as a rhythmic sub-division of the tempo beat value.

  • Division: Adjusts how the Delay parameter is divided between the four delays (A, B, C, D). The delays can be evenly spaced or spread out.

  • Feedback: Amount of Feedback for the delay line.

  • Feedback Path: When set to early, each voice feeds back immediately after it is delayed (these delays are controlled by the division knob). When set to late, all voices feedback at the same moment (i.e., at the longest delay time which is set by the delay knob).

  • Spread: Pans the voices left/right.

  • Tuning Speed - Adjust the speed of pitch shifting from snappy, hard tuned quantization to more subtle pitch correction. 0 to 200ms

  • Detune: Equally detunes all voices +/- 50 c.

  • Auto EQ: Boosts both low and high frequencies which often sound quieter after pitch shifting. This can help the pitch shifted voices sit better in the mix.

  • Glide A/B/C/D: Pitch shift interval for glide performance control.

  • Rise: Rise time for glide.

  • Fall: Fall time for glide.

Performance Parameters:

  • Root learn: Pressing the footswitch momentarily analyzes the note currently being sung, and updates the Root control (see above) accordingly.

  • Glide: Pitch shift to the glide interval.

  • Glide (Mom): Momentary pitch shift to the glide interval.
