11. Using Midi Controllers in Lightkey

Overview of External Control in LightKey

• Objective: Enhancing LightKey projects by utilizing external hardware to control the lighting rig beyond standard software interaction.

• Types of External Input Support:

  • DMX In: LightKey can receive DMX signals from other hardware, such as a separate lighting console, allowing that device to control LightKey functions.

  • MIDI Controllers: Devices with USB MIDI output (e.g., the Akai APC mini) are the primary hardware used for tactile control.

  • Computer Keyboard: Standard keyboard keys can be assigned as shortcuts to perform specific lighting cues or actions.

Simple Implementation via Live View

• Interface Context: Setting up external control is most direct within the "Live View," which contains pre-programmed cues (represented as faders or push buttons).

• Mapping a MIDI Trigger (Standard Procedure):

  1. Right-click on a specific cue (fader or push button).

  2. Navigate to External Control.

  3. Select Add Trigger.

  4. The software enters a "listening" mode; physical interaction with the MIDI controller (moving a fader or pressing a button) will automatically link that hardware component to the cue.

  5. A checkmark confirms the link, indicating the user now has full hardware control (e.g., using a physical fader on an Akai APC mini to control house light intensities).

• Visual Feedback and Compatibility:

  • Hardware Compatibility: Users should consult the LightKey website or user manual for a list of suggested MIDI controllers to ensure high levels of compatibility.

  • Two Levels of MIDI Interaction:

    • Control-Only: Standard communication from hardware to software.

    • Visual Feedback: Supported controllers (like the Akai APC mini) receive information back from LightKey. This allows the controller to provide a color preview or highlight the active cue on the physical hardware.

  • Benefit of Visual Feedback: It creates a greater awareness of the lighting rig's status without the operator needing to look at the computer screen or the physical stage.

Customizing Cue Colors on External Devices

• Dynamic Color Information: Buttons on MIDI controllers often mirror the color information programmed into the LightKey cue.

• Navigation to Color Settings:

  1. Right-click the cue.

  2. Select Get Info.

  3. In the Queue Editor, scroll down to the Button or Fader Color section.

• Color Logic:

  • Automatic: This is the default setting. It pulls color information directly from the fixtures on stage.

  • Custom: Allows the user to manually select any specific color for the button highlight.

  • Live Updates: As the user banks through different colors or changes settings in the software, the MIDI controller's lighting will update in real-time to match.

Advanced External Control Window Settings

• Accessing Internal Management: For more complex configurations or mapping non-cue actions, use the dedicated management window.

  • Pathway: Toolbar -> Window -> External Control.

  • Shortcut: Press $Command + E$.

• Control Tabs: The window is divided into three identical layouts for:

  1. DMX Control.

  2. MIDI Control.

  3. Keyboard Control.

• Configuration Management:

  • Users can manage multiple setups for different scenarios.

  • Examples: A dedicated setup for a "Easter service" versus a "default Sunday service."

  • Functionality: Configurations can be added, subtracted, or renamed to suit various needs.

MIDI and Keyboard Logic in Advanced Mode

• Input Selection: The Input setting determines which device LightKey listens to.

  • By default, it receives from any connected MIDI device.

  • To avoid interference from multiple connected controllers, the user can select a specific device for input.

• Trigger Identification: Selecting a trigger (such as a right arrow) in this window reveals its technical details:

  • MIDI Channel.

  • MIDI Note.

  • Control Change information.

  • This automated detection removes the need for manual data entry of MIDI notes.

• Action Assignment: Once a trigger is identified, the user can select an Action from a comprehensive list.

  • Example: Assigning a physical "next arrow" on the controller to the Next Cue button in a cue list.

  • Result: This allows for complete operation of the software without utilizing a keyboard or mouse.

Alternative Hardware and Economy Options

• Stream Decks: These devices can send MIDI commands through a MIDI module and are programmed identically to standard MIDI controllers in LightKey.

• Keyboard Shortcuts:

  • Used by simply pressing a key (e.g., 'a') and assigning it an action.

  • Value Proposition: An ideal, free alternative for those who cannot invest in external MIDI hardware.

• Value of External Hardware:

  • Controllers like the Akai APC mini are available for less than $100.

  • Provides professional-grade flexibility and tactile control, keeping the operator's focus on the stage rather than the software interface.
