GT1T alluded to the note charts being available. Here's a link to them:

(The link also provides the "optimum" activation points for all the songs in GH1, GH2, and GH2: 80s. He hasn't provided those points for GH3, I think because he wants people to figure them out for themselves, before using his program to determine them.)
