I made an account here so I can get advice from informed people since I am quite new to this. I have seen how people on youtube play the piano and their keys light up when playing a certain note. I am guessing this is built in the keyboard in most cases, however is it possible to craft something like this? I.e. an LED strip.
I have a Casio Privia Px 830 with a USB-B port. I would like to record my hands while playing and at the same time have my laptop record the midi file via USB.
How would I go about accomplishing this? Are there tutorials and if this has been asked already I am sorry.
All help is greatly appreciated.
