The Algorithms
The H9 offers a wide range of effects and can hold up to 99 Presets based on these effects.
Each of these effects is based on a unique algorithm. An algorithm is the underlying signal
processing structure of the effect – the signal processing software that creates the effect and
determines the ways in which the effect can be controlled (the algorithm’s “parameters”).
Each algorithm has a unique set of parameters which are varied by pressing the X, Y, or Z
buttons and turning the H9’s Knob. Presets are created by setting these parameters in a
unique way. Simply put, Presets are based on algorithms and the algorithms are the “secret
sauce.” Refer to the Algorithm User Guide for detailed descriptions of the algorithms and
their parameters. Additional algorithms are available as in app purchases. When you purchase
an algorithm, the presets built on that algorithm are included for free.
The Presets
The H9 Standard Edition and H9MAX ship with 99 (H9CORE has 25) factory-created Presets
based on Eventide’s unique Algorithms (additional Algorithms and Presets are available via in
app purchase). Whenever a Preset is loaded, the name of the Algorithm on which the Preset
is based is displayed momentarily. You can modify the sound of a Preset by pushing the X, Y,
Z, or HOTKNOB buttons and turning the Knob (or by using an Expression Pedal or MIDI) and,
if you wish, you can save the resulting effect as a new Preset. Instructions on saving Presets
are found later in this User Guide. Refer to the Preset Guide for details on the factory-installed
Presets.
The Knob, the LightRing & the Buttons
The H9 has one big Knob (Encoder) encircled by a LightRing and five ‘radio’ buttons
(HOTKNOB, X, Y, Z and Preset). The LightRing is used to indicate parameter settings and
values.
The Knob is used to:
1) Select and load Presets
2) Adjust Preset parameter values
3) Act as an on-board Expression Pedal
4) Dial-in tempo
5) Name Presets
6) Control and adjust various system settings
7) Toggle the action of the Right Footswitch between stepping up/down through the
Presets
The buttons are used to select the action of the Knob. When a button is pressed, its LED is lit,
the display indicates the parameter or preset name, and the Knob is active.
X, Y, Z buttons
Preset parameters are adjusted by pressing the X, Y, or Z button and then turning the Knob.
All three parameter buttons behave in the same way. Why three parameter buttons? In order
to get the most out of H9’s effects in a live situation, we believe that it’s important to give
you ‘top level’ control of the parameters that you’ll want to adjust on-the-fly.
When you press an X, Y, or Z button, its LED lights and the parameter name is displayed. Turn
the Knob to change the parameter’s value. The LightRing indicates the Parameter’s value (all
LEDs OFF indicates minimum, all ON maximum). Press the Knob to display the parameter’s
current value.
