#9801 Wormhole

Mega-sized, tilting reverb. How deep are you willing to go?

  • Mix: Wet/dry mixer, 0 is fully dry, 100 is fully wet.

  • Length: Wormhole distance in light years. Controls the decay time of the reverb. Internally tapered from 0 l.y. (shortest decay, 3s) to 100 l.y. (longest decay, 1000s). (0 to 100 l.y. or 30.67 parsecs).

  • Diameter: Width of the interstellar Wormhole. Controls the size of the reverb. A Diameter of 0 is tight enough to pull the ears off a gundark. A Diameter of 100 will fit Executor-class Super Star Destroyers eight abreast.

  • Lo Decay: Decay rate of the low frequency content of the reverb. 0 is quickest decay. 100 is slowest decay.

  • Hi Decay: Decay rate out of the high frequency content of the reverb. 0 is quickest decay. 100 is slowest decay.

  • Entry Field: Entrance characteristics to the Wormhole. Controls early reflections and diffusion in the reverb. 0 is a rougher entrance to the WormHole (less diffuse, noticeable early reflections). 100 is a smoother entrance to the Wormhole (more diffuse, less noticeable early reflections).

  • Pre Delay: Delay added before Wormhole entrance. (0 t0 2000ms)

  • Stability: Wormhole stability across time. Controls modulation depth of the reverb. 0% is the least stable Wormhole with large pitch variations happening to the reverb through time (max modulation/most unstable). 100% is a stable Wormhole with no reverb pitch variations through time (no modulation).

  • Stability Rate: Movement speed of an unstable Wormhole. Controls modulation rate of the reverb. Range is from 0 (slowest rate) to 100 (fastest modulation rate). Use in conjunction with the Stability control.

  • Warp Acceleration: How long it takes to traverse the wormhole and reach the top warp speed set by the Warp Factor control. Units are in total time to traverse the wormhole and lower values accelerate faster. Controls the rate of change of the reverb delay lines. (1.0 to 10s)

  • Warp Factor: Top warp speed desired through the wormhole. Higher Factors manifest as a higher final pitch changes. Warp Factor 10.00 theoretically highest possible speed. Controls the amount of change of the delay lines. (5 to 10s)

  • Warp Mix: Sets the mix level of the effect during warping, overrides the Mix control.

  • Warp Bass: Bass EQ control for Warp effect.

  • Warp Treble: Treble EQ control for Warp effect.

Performance Parameters

  • Warp (L): Latching switch. Press once to go thru the entire warping cycle. Footswitch unlatches after cycle completion.

  • Warp (M): Momentary switch. Hold to keep warp cycle engaged. Releasing before cycle completion generates a “deceleration” (decreasing pitch) sound to the warp effect.

#9802 Polyphony

A low-latency, high quality polyphonic pitch shifter capable of so much more. Making use of Eventide’s new SIFT (Spectral Instantaneous Frequency Tracking) technology, this algorithm shifts any chord or note you throw at it with zero tracking errors, all while the preserving the tone of your guitar. With this algorithm you can go from creating massive, organ-like chords and harmonies to out of this world special effects. The input signal is sent through the polyphonic pitch shifting engine which outputs two voices of shifted output - each with their own interval and detune controls. Included in the pitch shifting engine are the Auto EQ filters which help preserve the tone of the input signal. These filters are automatically adjusted based on the shifting interval to give the shifted voices as natural of a sound as possible, and the amount of filtering applied is adjustable. These voices are then fed to individual delays with independent time and feedback controls. The pitch shifting engine can be placed either inside or outside of this delay feedback loop, allowing you to create unique rising or sinking chorus sounds, and crystals type effects. Finally, the two voices can be independently panned when the output of the pedal is connected in stereo. As a cherry on top the latching or momentary Freeze performance switch allows you to infinitely sustain the pitch shifted sound while passing through the dry signal to create pad textures that you can play over.

  • Mix: Wet/dry mixer, 100% is all wet signal.

  • Inst Type: Tunes the underlying pitch shifting Algorithm for either pitched or percussive instruments.

    Tip

    The Percussive instrument mode is designed to prioritize preserving the transients and tone of the original signal while also having less latency. For applications where you would like to re-tune a guitar or bass (Mix is 100% wet) Percussive mode may work better for small shift intervals. For larger intervals the quality of the shifted sound will be be better in the Pitched mode.

  • Feedback Sw: Places the pitch shifter inside or outside of the feedback path.

    Because the pitch shifting is a mono in, multi out effect, the feedback paths of the shifted voices are summed together first before being fed back to the pitch shifter. This causes the feedback to slowly fade towards the center even if the voices are panned hard left/right when the pitch shifter is inside the feedback path. There is also a gentle lowpass filter in this mode to help remove some of the very very high annoying stuff that can happen when shifting up over and over again.

    Note: Feedback amounts may have different effects in one mode vs the other.

  • Auto EQ: Determines the amount of automatic EQ that is applied to the shifted voices to help them sound more natural. When shifting down the auto eq brightens things up to try and preserve the transients of the original signal. When shifting up, the auto eq smooths out harsh squeaky sounds. The EQ is automatically adjusted based on the amount of shift applied in either direction. A default setting of 10 is recommended.

The following parameters are available for both pitch A and B:

  • Level: Adjusts the volume of the pitch.

  • Shift: -2 Oct, -P12, -P11, -Oct, -M7, -m7, -M6, -m6, -P5, -Tri, -P4, -M3, -m3, -M2, -m2, Uni, m2, M2, m3, M3, P4, Tri, P5, m6, M6, m7, M7, Oct, P11, P12, 2 Oct

  • Detune: The amount of detuning, from -50 cents to 50 cents.

  • Delay: The amount of delay, from 0 ms to 2 s.

  • Feedback: The amount of feedback for each voice. Behaves differently depending on how Feedback Sw is set.

  • Pan: Moves the pitch left or right in the stereo field.

Performance Parameters

  • FREEZE: Freezes the pitch-shifiting sound for pad like textures. The dry signal is still passed through.

MIDI

When using the Freeze performance parameter, it is possible to send MIDI note data from a MIDI keyboard or sequencer to change the pitch shift intervals of Polyphony. The MIDI monitor window will display the pitch shifted amount in cents.

  • Glissando: Adjusts the amount of time it takes for the pitch shifted note to glide to the next note from 0 to 2000ms.

  • Sustain: Momentary will only change the pitch shifted value while an incoming MIDI note is ON, it will return to the Shift parameter’s value when the MIDI note is OFF. Latching will hold the value of the incoming MIDI note until it receives another MIDI note.

  • MIDI Channel: Sets which channel the algorithm will receive MIDI notes from. 1-16 or Omni.

  • Note Mode: Determines wether the MIDI note input is Mono or Poly.

  • Poly Mode: Determines how the incoming MIDI notes change the pitch shifted value. This parameter has no effect if Note Mode is Mono.

    • Normal: Voices are assigned in a round robin fashion.

    • Ordered: First note played is always Voice1. Then Voice2 and so on.

    • Spread1: All notes play if any keys are pressed. Voice1 is the highest, Voice2 is the next highest and so on. The note assignment happens every time you press a key. If you just press one note, all voices play the same note.

    • Spread2: Just like spread1 except that note assignment also happens when you lift up a key. When you lift up from a chord, you’re left with all voices playing one note.

#9805 PolyFlex

A fully polyphonic version of our classic, 2-voice PitchFlex algorithm, with a few added bonuses. Bend a chord into a new harmony, perform polyphonic dive bombs, or achieve pedal steel like tones. Fully equipped with detune, freeze, and individual controls for flexing either voice. The brand new Auto Engage feature allows you to preserve your dry signal while you are not flexing.

  • Mix: Wet/dry mixer, 100% is all wet signal.

  • Detune: A detune amount applied to both the base shift amount and the Flex amount, from -50 cents to 50 cents.

  • Flex Time: How long it takes to get from the Shift interval to the Flex interval from 0 to 2 seconds.

  • Return Time: How long it takes to return to the Shift interval from the Flex interval from 0 to 2 seconds.

  • Auto Engage: When on, the algorithm is bypassed until the Flex is engaged, or Manual Flex is above 0. This will be triggered by any of the available ways to Flex.

  • Auto Engage Hold Time: If Auto Engage is on, this parameter allows the pitch shifted effect to remain on for a period of time from 0 to 1 second. This can help the auto engage parameter from disengaging abruptly.

The following parameters are available for both pitch A and B:

  • Level: Adjusts the level of the pitch shifted voice.

  • Shift: The base pitch shift amount specified in musical intervals for each voice of shifting. -2 Oct, -P12, -P11, -Oct, -M7, -m7, -M6, -m6, -P5, -Tri, -P4, -M3, -m3, -M2, -m2, Uni, m2, M2, m3, M3, P4, Tri, P5, m6, M6, m7, M7, Oct, P11, P12, 2 Oct

  • Flex: The pitch shift amount to dive/bend to. -2 Oct, -P12, -P11, -Oct, -M7, -m7, -M6, -m6, -P5, -Tri, -P4, -M3, -m3, -M2, -m2, Uni, m2, M2, m3, M3, P4, Tri, P5, m6, M6, m7, M7, Oct, P11, P12, 2 Oct

  • Pan: Moves the pitch left or right in the stereo field.

Performance Parameters

  • FLEX (A/B) - Momentary or latching performance parameter to activate the pitch bend/dive for each shifted voice. Current pitch shift is determined by whichever control was touched last (this or the manual flex knob/external controller)

  • Flex Dual - Momentary or latching performance parameter to bend/dive both voices at the same time. Current pitch shift is determined by whichever control was touched last (this or the manual flex knob/external controller)

  • FREEZE: Freezes the pitch-shifiting sound for pad like textures. The dry signal is still passed through. Note that if Auto Engage is On, you won’t hear the frozen signal when you are not flexing.
