It is hard but not that hard mate to be honest id say Logic is easyer but they dont make it for pcs anymore thats why i dont use it now.

In my opinion aside from those 2 nothing els is worth considering if you plan to take it seriously.Pro tools is good to but i dont know enough about it to comment.

Its not that difficult to work Cuebass im not particularly good with it to be honest my knollege of it is pathetic compared to some of the people on hear but i get some pretty good reults with it
,you just need to know what your looking for when trying to find a function.For instance loading an audio file or wave if you like just post a question and im sure some will answer it.I will if i can but im sure someone will beat me to it..lol

Anyway just keep on trying im sure youl get thier in the end and youl be glad you took the time to lern coz one thing is for sure with music prodution the results are very rewarding
