I am currently trying to make a VU Meter bridge for DAWs (I'm using logic but I would like it to be universal).
I have the front end worked out with 8x 5 Volt VU meters backlit by RGB LEDs fading from green through orange and red.
At the moment I'm using a pot to simulate a signal from the daw to check I could get it to work in principle. Now I have to replace this with an actual channel level output from logic (or any other daw).
So I've been looking at using Mackie HUI protocol and I have found this document. http://stash.reaper.fm/12332/HUI.pdf
Which I don't really understand. I don't really know where to start on making the ardunio visible to the DAW as a HUI controller and then how to get the arduino to interpret the data outlined in this document (on page 5).
Can anyone help or perhaps point me in the right direction? It would be much appreciated.
