On the Elements section, click the Add button to add an Onyx element to the project:
Lighting > Obsidian > Onyx
Click the toggle buttons on the element to enable it.
Use the Add button again to add your MIDI device element through External Control > MIDI. Currently, RD/ShowCockpit has out-of-the-box support for multiple MIDI devices - check out the complete compatibility list here.
When using a specific MIDI device driver, you can skip to Step 4.
After adding the element, make sure that the correct device is selected under both Input Device and Output Device options.
Finally, click the toggle button on the MIDI device element to enable it.
In case you selected the Generic MIDI driver, now you need to "teach" this driver what controls (faders, buttons and encoders) your device has. For the officially supported MIDI devices, controls are automatically mapped, so you can skip to the next step.
Double-click the Generic MIDI element to open its window - you will start by mapping the Faders. Click on Enable Learn on the top-right to start listening to MIDI input.
Move, one-by-one, all Faders on your MIDI device. They will be added to the Faders list.
To map the Buttons, click on Buttons (above the table) and repeat the procedure now for all your device buttons.
Finally, map your Encoders by clicking on Encoders and repeat the procedure for all the encoders.
You can now close the Generic MIDI window by clicking Back to Elements or clicking on any menu button.
Open the Mapping section on the Main Menu.
This section is divided into 3 columns, from left to right:
Select the Onyx element on the Functions column and select a function (for example, "Main Playback Fader"). When you select the function, the button will be highlighted and the second column will have the parameters for the function. In this case, you can select which playback fader you want to control.
Select the Generic MIDI element on the Controls column, open the Faders list and click on one of the faders to assign the function.
If you now move your fader, the mapped Main Playback Fader on Onyx should act accordingly.
Repeat the process for all desired controls.
