I just had a thought. I love using Logic Pro and after X came out even moreso. The only thing is everything I find that is up my alley is for Ableton. I'm in the process of learning Ableton Live but I had a thought for Logic Pro users.
What if one utilizes Touch Tracks in the Environment window to trigger midi regions, with the LED light configuration you want? Assigning that midi region to a specific key for triggering and maybe splitting the MIDI message with an ornament object to send the MIDI LED data and the key press. Just an idea but I think it's very possible. I'll test it out tonight if I have time and post sometime tomorrow the results.
