objects flash to midi daw send. How?

[Digital Drum]

The lemur iPad interface is a great extension to control bitwig from my electric drums(TD-20). I have working faders for click volume and every drum. It would be nice if my faders and objects could flash when the corresponding drum was hit or signal from a daw track including tempo from BW. This would allow me visual feedback for quick mixing. I absolutely see the advantage to scripting, though I've tried and tried to make this happen. So I'm asking two things.... 1. What is the best way to get to know the scripting process particular to midi, (reference materials), and 2. Will one of you teach me how to do what i want to achieve. Thanks.
