Too messy
I'm sorry, but this needs a major overhaul badly - I would certainly suggest that you head back to the drawing board with this and start from scratch. How many different tunes did you want to try and play at the same time?!
When more than 3 of these individual sounds merge together at the same time, it becomes quite messy and it's impossible to enjoy them as the individual pieces, or enjoy the piece that you've thrown together as a whole. Try taking some out and adding new ones in, not stapling more and more over the top, as it become unsustainable very quickly.
Perhaps start with the sort of game that you would focus the music for, then work to that, chopping and changing the pieces of the puzzle as necessary.
