Help with some FC in Rock Band 3 DS

[qLL]

I played the rb3 on DS since it was released, and i fc almost every song ( 22 of 25 songs) of this game, exceptions for:

Crazy train: cant nail the solo, seems improsible to 100% it, even on dark malafeew control scheme

(video of crazy train on expert. NOT ME. the fc on the video was tool assisted, as said on the description)

Roundabout: the keys solo, same thing as crazy train

Lasso: drums part: looks too fast to nail it, and i cant get the right patern for it

just missing this song to fc every song in rock band 3 DS. ( planning to do fc LRB too
