F. Algorithm List

The best way to quickly find the best effect for a given application is to make use of the H9000’s powerful real-time database features, either on the front panel’s Algorithm List page, or in Emote’s Browser Window.

To get an overview, as well as a feel for the wide selection of effects the H9000 offers, a stroll through this manual is recommended. The algorithms are grouped by bank and placed in numerical order. Any numbered algorithm can be quickly found by using its top two digits (one digit for a 3 digit number) as the Bank Number.

A given algorithm may be identified by its name or its number. Many algorithms are supplied in several versions with the same name and number - they can be further distinguished by the number of channels they process, and the audio sample rates they can handle.

Sometimes, a number of algorithms may share the same basic structure or algorithm. Different versions of this structure will be provided, with their parameter values carefully tuned to produce a desired effect - these variants are popularly known as tweaks.


Each algorithm will be labeled either 48, meaning that it can only operate up to 48kHz sampling, or 96, meaning that it can operate at all the H9000’s supported sample rates.

A given algorithm may have from 0 to 8 inputs and from 0 to 8 outputs. An algorithm with no inputs is typically an oscillator or other generator, whereas an algorithm with no outputs is usually a display-only device. Some utility calculators have neither inputs or outputs – these will block any signal routed through them.


Many algorithms are flagged with recommended source material or application types:

  • [V] Vocal

  • [G] Guitar

  • [D] Drums

  • [B] Bass

  • [H] Brass

  • [S] Surround

  • [P] Spoken Voice

  • [R] Strings

  • [K] Keyboard

  • [X] Special Effects

The H9000 offers the following effect types - any given algorithm may have a combination of some or all of them:

  • {P} Pitch: Eventide invented the concept of the pitch shifting effect and is the leader in the field. The H9000 offers a wide variety of pitch shifting effects such a Diatonic, MicroPitch, and Reverse shifters, as well as the more familiar Chromatic variety.

  • {R} Reverb: A reverb may range from an emulation of a spring line to a grand canyon.

  • {D} Delay: Digital delays ranging from a few samples up to several minutes.

  • {E} EQ: The equalization offered by the H9000 ranges from simple “high cut” tone controls to 32 band multi-channel parametric equalizers.

  • {M} Modulation: The way a parameter of the effect may be controlled or swept by a slow-running oscillator or other signal source. This allows a range of effects including auto-panners, tremolos and vibratos, as well as flangers and phasers when modulation is applied to delay or filter elements.

  • {Y} Dynamics: A general term describing a range of amplitude-sensitive effects, covering the field from compressors to envelope followers.

  • {N} Enhancer: Add air, shine, sparkle, thickness, width. Our “sound better” boxes.

  • {Z} Distortion: Impart gentle tube warmth or shred through a dying power supply. Up to you.

  • {U} Utilities: Simple, effective.

  • {O} Other: Hybrid and otherwise hard to categorize effects.
