On the Elements section, click the Add button to add one element to the project:
External Control > OSC > Generic OSC
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.
Double-click the Generic OSC element and add your OSC Functions to the Outputs list:
Name: name identifier of your control
Address: the OSC address
ValueIndex: (ignored for functions)
Range: min and max values for internal normalization
Type: button, fader or encoder
Open the Mapping section and select the desired OSC Output functions. Start by selecting the OSC Output element on the left list (functions) and the desired output.
Finally select the MIDI Device on the right list (controls) and assign the previously selected OSC function to one of your controls.
