Hang on, there.
I think that the Cakewalk Sound Center - included in the trial - come with access to something like 150 sounds of some sort.
I just did a Google search for "Cakewalk Sound Center" and got this back:
http://www.cakewalk.com/P.../Cakewalk-Sound-Center Soooooooooooo, check it out and see if that can at least give you something to play around with,
I can tell you that I have LOVED Sonar since before it was Sonar - well over 20 years now, and I find it fits every one of my needs quite nicely. I believe some of the recent XBox games were scored with Sonar, and possible the movie Battleship (I am by NO means sure - that's just what my head thinks is the case).
It is a really nice set of tools to record through master - I call that cohesive function, and the community for Sonar is FULL of helpful folks to help explain things to you while you are learning.
If you awns me a private message requesting additional access, I will respond with a cell number you can call if things get too wacky for typing,
Welcome to it all, we embrace your newness.
