Yes, it’s an expensive hobby. I now define it as “research” in my company so it becomes an expense 🙂
I also use Logic Pro, and I use the Opus East/West symphonic library for rendering. That maxes out my budget already (and my diskspace!)
Using libraries is complicated, I think. I’ve learned a lot by doing (and redoing) many times. Logic isn’t my ideal system, but I sort of know how to do stuff now…
