Hi Danjas,
Regarding point 1, not sure but maybe the ACL Sinfonion can do this, you might want to check that module out. The con is the price.
About point 2 not too sure what you want, do you mean something like a random generator or something like that? If yes, there are several random generator modules, just go in this forum at modules and look there for what you might need.
Kind regards, Garfield Modular.
