5.5. Algorithms

algorithm screen

In the H9000, each FX chain can contain up to four separate signal processing algorithms. The Algorithms screen is where you work with these algorithms; you can navigate to it by:

  • Pressing the Algorithms button on the front panel.

  • Highlighting the Edit button in the center portion of an FX chain block, then pressing the Enter button.

The screen will switch to the Algorithms display and the front panel Algorithms button will illuminate.

5.5.1. Algorithms Overview

The Algorithms overview screen displays the algorithms that make up the currently highlighted FX chain. The display shows the different algorithms present, their routing within the FX chain, and the audio inputs/outputs that feed the FX chain.

Rotate the wheel to navigate to the different objects in the FX chain, which include:

  • Algorithm processing blocks

  • Input and Output blocks

When viewing the Algorithms screen, pressing the Enter button works contextually for whatever object you have highlighted:

  • Algorithm: When the Edit label is highlighted, pressing Enter takes you to the Parameters view page (see the Parameters section for more details) When the Replace label is highlighted, pressing Enter takes you to the main list of algorithms to choose from.

  • I/O Label: Pressing Enter takes you to the editor screen for the audio inputs/outputs.

5.5.2. Configuring Audio I/O For an Algorithm

To configure the audio I/O on the Algorithms view screen:

  • Use the cursor keys to highlight the audio input or output block you wish to configure, and press the Enter key.

  • You can then use the cursor keys to highlight the audio I/O category (Analog, Digital, USB, Expansion Card), then cursor over to the channel number and adjust it separately. This type of fine-tuned I/O control is particularly important when an expansion card is present, which can have 32 I/O channels per slot.

  • Use the wheel to cycle through the available input or output assignments.

5.5.3. Algorithm Screen Soft Keys

The Algorithms view screen contains eight Soft Keys:

Add Algorithm
  • Press the Add Algorithm soft key to add a new algorithm to the currently selected FX chain. A new algorithm block will appear labeled “Select Algorithm”.

  • Use the cursor keys to highlight the “Select Algorithm” block and press the Enter key.

algorithm screen
  • Use the navigation controls to select an algorithm. Each entry contains helpful info (Ins/Outs, a description of the algorithm, tips on its use, etc.).

algorithm select
Delete

Press the Delete soft key to remove the highlighted algorithm from the FX chain.

Move

Press the latching Move soft key to change the location of an algorithm within the FX chain. You can move the algorithm in an FX chain to be above or below any other algorithm in series, or next to another algorithm in parallel.

Expert Router

The H9000 allows not only serial routing of algorithms, but also parallel and mixed serial/parallel routing too. The expert router page is where you can view and control this aspect of the routing. Press the latching Expert Router soft key. The display switches to a graphical routing matrix, where you can view and edit a high level overview of all of the algorithms present in the current FX chains, their audio I/O assignments, and their signal routing configuration.

To make adjustments in the Expert Router screen:

  • Use the cursor keys to highlight the aspect of the block diagram you wish to adjust (audio I/O block, routing, Algorithm).

  • Use the wheel to adjust a highlighted audio I/O routing.

  • Use the Move soft key to adjust a routing pathway when it is highlighted.

Mix

Press the latching Mix soft key to change the display to a set of mixing controls, which adjust the relative level of each algorithm within the FX chain. Navigate to the algorithm whose mix you wish to adjust, then rotate the wheel to change it.

Mute/Bypass

Press the Mute/Bypass soft key to mute the audio output of the currently highlighted algorithm. A red “M” label will appear at the right of the algorithm block when muted. Press the Mute/Bypass soft key again to unmute the audio output.

Long-press the Mute/Bypass soft key to bypass the currently highlighted algorithm. A red “B” label will appear at the right of the algorithm block when bypassed. Long-press the Mute/Bypass soft key again to un-bypass the audio output.

Gain

Press the latching Gain soft key to change the display to a set of gain controls which adjust the output level of each algorithm within the FX chain. The difference between the Gain control and Mix control is that Gain determines the overall signal presence of an algorithm in a FX chain, whereas Mix controls the overall Wet/Dry mix of an individual algorithm and its signal.

List

Press the latching List soft key to view the main list of all algorithms available on the H9000.

algorithm list

To the right of the list is a description field that shows information for the currently highlighted algorithm, including the name, the product from which it is sourced, the numbers of inputs and outputs available, and a description of the algorithm. Note that the description field will usually contain more text than can fit on the display; in this case, use the cursor keys to highlight the description field, then rotate the wheel to view the remaining text. The List screen the contains following soft keys:

  • Show Presets: Some algorithms also contain Presets, which are variations of each algorithm with their parameters configured for different sounds. Press the latching Show Presets soft key to show/hide the presets contained within each algorithm.

  • Sort Options: Press the Sort Options soft key to select which way the algorithms are sorted, including ID Ascending, ID Descending, Name, Recently Used, and Most Used. Use the cursor up/down keys to navigate to the sort option you wish to use, and then press the Enter key.

  • Jump to Loaded: Press this soft key to jump to the algorithm that is currently loaded in the FX chain.

  • Search: Press the latching Search soft key to bring up the virtual keypad and enter letters and numbers to search for an algorithm name. As you enter more characters, the list is filtered to show only algorithms that contain the characters you have typed.

  • Tags: Press the latching Tags soft key to switch the right-hand side of the display to the Tags screen. You will be presented with a list of tag categories, which you can select with the cursor keys and enter key. Tag categories are: Effect Type, Product Type, Instrument Type, and Ins/Outs.

    Once you have selected a tag category, you will be presented with a menu of tags within that category. Use the cursor keys and Enter key to select a tag; it will then be added to the current tag list and be shown above the tag list. You can select as many tags at once as you like.

    As you add tags, the main list of algorithms will be filtered to only show algorithms that contain text matching the tag(s) you have selected. This powerful feature is a great way to narrow down the H9000’s vast list of algorithms to a more manageable selection, one that is appropriate for the task at hand.

  • Clear: Press the Clear soft key to clear all currently selected tags and return the main list of algorithms to its unfiltered state.

  • More: Press the More soft key repeatedly to switch the soft keys above it to alternate functions. These additional soft keys include:

    • Jump to Last: Press this soft key to jump to the previously loaded algorithm.

    • Bank Up/Bank Down: Press these two soft keys to quickly jump to the next/previous bank of algorithms. The H9000 algorithms are organized into different banks, each one representing different categories of effects. Each bank begins with a new 3-digit number (100, 200, etc.)

    • Rename: Press the Rename soft key to rename the currently highlighted algorithm. Factory algorithms cannot be renamed.

    • Delete: Press the Delete soft key to delete the currently highlighted algorithm. Factory algorithms cannot be deleted.
