Thank you! Ye, when I first optimised this one, I thought to do some more, but until now I haven't done that. But I will definitely do it as said some time ago.
I keep improving so I think my newer tracks will always be better than my previous ones. I don't know anymore how I 'invented' the synth chord, but you can look up how it's made.
Sweet track - your best yet, in my opinion :) Everything is really well mixed and those transitions are beautiful :) Also, I've been trying to make a chord synth like that for ages, I'm gonna have to take a look at that ;)
