Well it sounds like you are doing the same stuff I am with the computer. I got my hands on a program called Orchestal and did a musical score to another Galactica project that I and a few others had on the go. It was unbelievable how real it sounded was compared to a real Orchestra.
Like I said in another thread, Cool edit is the cats meow in my book. Another great program is Fruity loops. Ya I know the name sucks lol but the program is great for a drum machine. It has all the fake sounding drums but you can put samples of real drums in there ,do your patterns per bar and then place the patterns where ever to make a complete drum track. You can also download each piece as it's own wav, put it in cool edit and work on your complete kit for sound , one piece at a time just as you would in a studio.
By all means send me your samples for the project.
Thanks
