Contact UsLightkey 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 |
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:
For more information see the Behringer BCF2000 User Guide.
To enable feedback LEDs on the Akai LPD8 controller, do the following:
To enable the feedback LEDs on Native Instruments controllers, some additional setup may be necessary in Lightkey’s DMX Output preferences:
Choose Lightkey > Preferences… and then click External Control.
Locate the output to your controller in the list and make sure it is enabled.
Control-click the input from your controller, select Send Feedback To, and then select the controller’s output.
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.
Open Audio MIDI Setup and choose Window > Show MIDI Studio.
Choose MIDI Studio > Open MIDI Network Setup… to open the MIDI Network Setup window.
Click “+” in the My Sessions section. This creates a “session” which other computers can connect to.
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.
Make sure the Enabled checkbox is selected.
Select “Anyone” in the menu “Who may connect to me”.
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.
Repeat the above steps to create a session in Audio MIDI Setup.
In the Directory section, select the session you first created on the destination computer.
Click Connect. The two computers are now connected so MIDI can be transmitted between them.
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.
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.
