LrControl supports the iControls Pro with the device default settings. So after you have installed LrControl, you can just take it out of the box, plug it in and it will work with LrControl.
The function of each control on the device can be changed using layers. Each layer defines the meaning of each encoder and fader.
Important! Leave the device layer always on the first layer. And only use the layers of the LrControl plug-in. Make sure the first LED above buttons 'a' and 'b' is illuminated. Use the buttons to select the first layer.
The LrControl layers are selected using the row of Solo buttons. The selected Solo button will light up.
Using the Sel Buttons
When you power-up the device it is automatically using the device-layer 1, the LED marked 1 is burning in the top left corner of the device. In this mode, the Sel buttons cannot be used, because the message they send is also sent when using the knobs and sliders.
If you want to use these Sel buttons, it is necessary to re-program the device. Most of the work is already done, you can download a complete setup for the iControl Pro that allows you to use the Sel buttons as well.
Download iControls Pro iMap application
Use this application to send a new configuration to the controller. Download the version for your platform and install it.
Download iControls Pro configuration for LrControl
Load this file in the iMap application and send it to the device. Then select the second LED in the top left corner using the buttons below the LEDS. Remember to always select this second LED after powering on the device.
Download mapping for shuttle wheel
The big wheel in the bottom left behaviour is erratic. It sends different messages depending on what you did previously. To simply make it always do previous or next photo, download this file and import if from the "Controller Setup" dialog in LrControl.
The iControls Pro is out of production. If you want one, maybe you can find one on eBay.
