5.6. Parameters


Each algorithm contains a set of parameters; you adjust these parameters to adjust the sound of the algorithm you have selected.

For example, a reverb algorithm contains parameters for settings such as room size, decay time, pre-delay, and so on. The Parameters screen allows you to view and adjust these parameters.

To switch to the Parameters screen:

  • When the Edit label is highlighted, press the Enter key when an algorithm is highlighted. You will be taken to the Parameters screen for that algorithm.

  • Alternatively, press the front panel Parameters button.

The Parameters view page offers a handy list on the left-hand side of the screen, which displays:

  • The general parameters for the current FX chain container.

  • The algorithms currently loaded in the selected FX chain.

  • The parameter categories within each algorithm.

Use the cursor keys to highlight the parameter category for which you wish to view the parameters for. The screen will then display the parameters for only that category. Many algorithms contain a lot of parameters, and a single list could be cumbersome.

5.6.1. Editing Parameters in an Algorithm

To adjust a specific parameter:

  • Use the cursor up/down keys to navigate to a parameter category. The right-hand side of the screen will display the parameters within that category.

  • Use the cursor keys to highlight the parameter you wish to adjust.

  • Use the Enter key and/or wheel to adjust the parameter you have highlighted. Note that you can hold the Enter key while scrolling to make fine-tuned parameter adjustments.


You can also use the two middle-left soft keys to page up/down among the parameter categories, or the two outer-left soft keys to page up/down through the algorithms, while highlighting parameters within the parameter view. This can be a faster way to work than using the cursor keys exclusively; you can jump around the screen quickly and don’t need to constantly “cursor left” back to the parameter category list.

The parameters screen contains four additional soft keys:

Quick Map

Press the latching Quick Map soft key to bring up the quick mapping function for the parameters you are viewing.


The quick map feature is extremely powerful, as it lets you quickly map a wide variety of external controllers to any algorithm parameter. Different aspects of the effects can be adjusted in real time using MIDI controllers, expression pedals, footswitches, control voltages, etc.

The MIDI functionality on the H9000 is “plug and play”. You can connect a MIDI device to the 5-pin MIDI-in DIN port, or connect a MIDI class compliant interface to one of the USB connectors. All MIDI Channel configuration is done when individual controllers are mapped, as opposed to in a central MIDI settings screen.

You can map multiple parameters to a single external control source; you cannot, however, have multiple control sources affect a single parameter.

For more complex mapping of multiple parameters to a single control source, please refer to the Functions section of this user manual.

The Quick Map feature works as follows:

  • Press the Quick Map soft key; you will see a “Press Enter to Learn” label superimposed over each of the parameters on the screen.

  • Use the cursor buttons to navigate to the parameter that you wish to map a controller to.

  • Press the Enter button; the highlighted parameter’s label will change to “Move Any Controller”.

  • Move the external control that you wish to pair to the highlighted parameter.

  • The external controller and the parameter are now paired.

Custom Map

The Custom Map feature is also designed to map controllers to H9000 parameters, but with a much finer level of control. It works as follows:

  • Use the cursor buttons to navigate to the parameter you wish to custom map a controller to, then press the Custom Map soft key.

  • The “Controller Type” pop-up menu will appear, where you can select from the following mapping options:

    • Expression Pedal 1-4

    • Switch 1-6

    • Note On

    • Poly Pressure

    • MIDI CC Single

    • MIDI CC Double

    • MIDI Program Change

    • Channel Pressure

    • Pitch Wheel

    • MIDI Start

    • MIDI Stop

    • Function 1-8

    • Off

  • Navigate to the controller type you wish to use then press the Enter key.

  • You will then be presented with an additional set of controls that allow you to refine the mapping: Control Minimum, Control Maximum, Value Minimum, and Value Maximum.

custom map
  • Use the cursor keys to navigate between the Control Range and Parameter range controls.

  • Press the MIN/MAX soft key to toggle between adjusting the minimum or maximum value of a parameter, then use the wheel to set its value.

    Note that it is possible to change the direction of an external control source by inverting its min/max values. For example, if you set the Max value to 0 and the Min value to 100, when you move your external control source the mapped parameter will move in the opposite direction.

  • When you have finished, press the OK soft key and the custom mapping will be completed.

  • The display will return to the Parameters display. You will now see a green text label above the parameter, showing you the specific controller you have mapped to that parameter.

  • To delete a custom mapping, use the cursor to navigate to the parameter mapping that you would like to delete, and press the Custom Map soft key. In the Controller Type menu, select “Off” and the mapping will be deleted.


Press the Random soft key to assign random values to each and every parameter of the current algorithm. This creative function allows you to try out different algorithms in a free-form “what-if” type scenario, because the different parameter values are all selected with no specific purpose or sound in mind. Give it a whirl with your favorite algorithm and see what happens…


Functions in the H9000 act much like Macros in Ableton Live; they are groupings of parameters that can be adjusted with a single knob. There are eight Functions available in each FX chain.

Every function has three parameters available:

  1. Range: Press the latching Range soft key to adjust the range of each parameter mapped to any given Function. Each parameter that belongs to a Function has a defined range; it can be as large as the true Minimum/Maximum range of the parameter, or anywhere in-between. The main Function knobs then cause each parameter change to be scaled according to its defined range.

    functions range

    You can use the Min/Max soft key to toggle between adjusting the minimum or maximum value of a parameter’s range, as indicated by the white and green end cap markers. These Min/Max values only apply to parameters mapped to a Function knob, not the Function knob itself. To set a min/max value for a Function knob, use the Custom Map feature in the External Control settings.

    As detailed earlier in the Custom Map settings, you can change the direction of a parameter’s value by inverting the min/max end cap markers. This can be useful for having one Function knob control multiple parameters that move in different directions.

  2. Map: Press the Map soft key to map specific parameters to the selected Function knob. The Map view displays a condensed view of all the parameters in the FX Chain, allowing their selection for assigning to Functions. The Add/Remove soft key assigns/unassigns the parameter of the selected Function.

    functions map
    • Highlight the Function knob on the left side of the display.

    • Use the cursor up/down keys to select which of the eight Functions to work with.

    • A list of available parameters will appear; use the cursor up/down keys to highlight the Function you wish to map.

    • Press the Add/Remove or Enter key; the highlighted parameter is now mapped to the Function knob you had selected, and that Function’s number (e.g., F1) now appears on the left side of that parameter’s entry in the list.

    • If a Function is already mapped to a parameter you have highlighted, pressing the Add/Remove soft key will remove the mapping.

  3. External Control: Press the External Control soft key to map external controllers to any given Function knob.

    functions external control
    • Use the cursor keys to highlight one of the eight Functions.

    • Press the Enter key to learn a command.

    • Move a control on your external controller; that control will now be mapped to the highlighted Function.

The Custom Map dialog can also be accessed through this interface and used the same way as for individual parameters.
