Although U can do creative stuff on it I tend 2 think that it's more of a loop on loop package, perfect for what it's name says, and not so much 4 creating new stuff (although like I said, u could do it but I don't think it's really designed along those lines!).
Yes U can have more than 8 channels (edit/ insert Track... ctrl+T)...
No much in the way of a fan but I can see how it may come in handy!
