Hey everyone,
I am really new to this kind of stuff, so I apologize for every inconvenience due to my noobquestions.
I set up the midi manager and it can find my digital piano. So far so good.
But how can I get the input to trigger events?
Actually I want to visualize every key on the digital piano (76 keys) to one special color (ex. a colored point light or a emissive material) . So when I play I can see my playing visualized on a screen.
So I have the midi manager and the set up for the light, but I don’t know how I can get the part with the input and the keymapping?
Was that understandable? 
UPDATE:
I figured out, that I wrote the input device wrong. So now I can get a input, but I can’t seperate the different keys. So it fires the event ( pointlight) with all keys. I looked into the output log for the Control ID, but somehow if I call the note on or note off function and write a controlID into it, it doesn’t change.
Can someone help me, how can I get the Control ID in the right way?
Okay, I fixed it myself. If anyone have the same problem, I can help you out now.
^.^
@.reynolds Great setup by the way. Totally works well for me!
If I am done with the artistic stuff, I will post a video.
