Euphonix: Getting to Know Knobsets

When using the Euphonix devices with Logic Express, the Mixer’s channel strip functions can be accessed and edited using knobsets. A knobset contains pages, each comprised of eight parameters. Knobsets are organized hierarchically.

The top-level knobset leads to the following knobsets:

Euphonix: Using the Inserts (Configuration) Knobset

This knobset allows you to:

  • Edit an effect plug-in (Inserts mode)

  • Change or insert an effect plug-in (Inserts Configuration mode)

Note: This knobset only relates to insert effects, and not to instrument plug-ins.

Editing Effect Plug-ins

You edit effect plug-ins in Inserts mode, using the Inserts knobset.

To edit an effect plug-in
  1. Press the Inserts knob top, or key, to display all effect plug-ins inserted in the currently selected channel strip. This key is labeled “*” (asterisk) on the CM408T channel strip.

    Note: If using the MC Mix, press the CHAN key to enter Channel mode.

    The effect plug-in names are displayed on the Soft Keys, the touchscreen, or the display, depending on the system you are using.

    If more than eight effect plug-ins are inserted, you can use the Page keys to display ensuing plug-ins.

  2. Press the knob top that features the name of the effect plug-in you want to edit.

    The parameters are displayed in the order shown in the Controls view of the effect.

  3. Turn the respective knob to change the value.

    Depending on the system you are using, for parameters with only two values, you can either press the On key, or turn the respective knob, to switch between the two values. The On key is lit when the value is 1 (or on) and unlit when the value is 0 (or off).

    Pressing a knob top sets the controlled parameter to its default value.

    If there are more than eight parameters, use the Page keys to navigate between them.

  4. Press the Back key to return to the top-level knobset.
