Hardware Controllers

  • Which MIDI controllers support feedback with multiple colors?

    Lightkey sends feedback to any connected MIDI controller so it can reflect the current software state through LEDs or motorized knobs, faders etc. Beyond that, some MIDI controllers can display multiple states with different colors.

    Currently Lightkey supports this extended feedback for the following controllers:

    MIDI controller Feedback type
    Akai APC mini dual-color feedback
    Akai APC20 dual-color feedback
    Akai APC40 dual-color feedback
    Akai APC40 mkII multi-color feedback
    Novation Launchpad dual-color feedback
    Novation Launchpad Mini dual-color feedback
    Novation Launchpad Mini MK3 RGB color feedback
    Novation Launchpad MK2 RGB color feedback
    Novation Launchpad Pro RGB color feedback
  • How do I set up push buttons on a Behringer BCF2000 to show the current state?

    You can set up the push buttons on a Behringer BCF2000 MIDI controller so their LED reflects the current state of the binding. For example, the LED is on when the corresponding cue is active, and off otherwise.

    Program the push button (Edit button) with the following options:

    • MIDI data type: CC (Control Change)
    • On value: 127
    • Off value: 0
    • Controller mode: Toggle on

    For more information see the Behringer BCF2000 User Guide.

  • How do I set up 14-bit faders on a Behringer BCF2000?

    The faders on a Behringer BCF2000 MIDI controller can send high-resolution 14-bit values to Lightkey. In this case the faders provide a range of 16384 steps as opposed to 128 steps for standard resolution.

    Program the fader (Edit button) with the following options:

    • MIDI data type: CC (Control Change)
    • Min. value: 0
    • Max. value: 16383
    • Controller mode: Absolute 14-bit (“A 14”)

    For more information see the Behringer BCF2000 User Guide.

  • How do I set up LED feedback on an Akai LPD8?

    To enable feedback LEDs on the Akai LPD8 controller, do the following:

    • Activate the Pad button at the lower left. This makes the pads send Note On/Off messages.
    • In the software editor, make sure the pads are set to “Momentary” (the default option).
  • How do I set up LED feedback on Native Instruments controllers?

    To enable the feedback LEDs on Native Instruments controllers, some additional setup may be necessary in Lightkey’s DMX Output preferences:

    1. Choose Lightkey > Preferences… and then click External Control.

    2. Locate the output to your controller in the list and make sure it is enabled.

    3. Control-click the input from your controller, select Send Feedback To, and then select the controller’s output.

Other Applications

  • How can I receive MIDI from another computer?

    It’s easy to receive MIDI commands in Lightkey from other apps on the same Mac, e.g. Ableton Live or ProPresenter. If the sending app is on another computer, you need to route the MIDI commands over a local network. This is done with the app Audio MIDI Setup that comes with every Mac.

    Note: If you use Live Triggers, Lightkey and Ableton Live must be on the same Mac while you create your projects. This is necessary so Lightkey can add clips to the Ableton Live library. But after everything has been set up you can run the show from separate computers.

    On the computer running Lightkey:
    1. Open Audio MIDI Setup and choose Window > Show MIDI Studio.

    2. Choose MIDI Studio > Open MIDI Network Setup… to open the MIDI Network Setup window.

    3. Click “+” in the My Sessions section. This creates a “session” which other computers can connect to.

    4. On the right side of the window, change the local name and Bonjour name of the session. The Bonjour name will be visible to other computers.

    5. Make sure the Enabled checkbox is selected.

    6. Select “Anyone” in the menu “Who may connect to me”.

    7. To verify that Lightkey is connected to the session, open Lightkey’s Preferences window, click External Control, and check if the network session is selected under Input.

    On the computer running Ableton Live or another software:
    1. Repeat the above steps to create a session in Audio MIDI Setup.

    2. In the Directory section, select the session you first created on the destination computer.

    3. Click Connect. The two computers are now connected so MIDI can be transmitted between them.

    4. In the software which you want to use to send MIDI, select the network session as destination. In Ableton Live this is done in the Preferences window > Link/MIDI.

  • Live Triggers: Can I use the Consolidate command in Ableton Live?

    The Consolidate feature in Ableton Live can be used to merge multiple clips into one. This is particularly useful when you want to transfer a clip to Session view.

    You can use this command with Live Triggers, but only for cues on the same Live page.
