It's a learning curve for sure, but worth it.
Back in late summer of 2012 my cousin took one of my viola concertos and ran it through the normal Vienna Suite plug-ins (he had a trial version) and it really brought the music to life. Fast-forwarding to November of 2016 I bought the Pro Edition of Vienna Suite after saving up and I couldn't believe how much better the Pro Edition was than the normal version. The price may be steep but there is a good reason why, these plug-ins are top of the line bar-none. Word of caution though, do not use this with Vienna Ensemble Pro 5 because the entire program will crash; Suite Pro is best used with Ensemble Pro 6. I'm still learning more about the different plug-ins and the numerous things I can do to my music with them, but that's fine because I learn something new every time I use it. Here's what I like about Suite Pro:
1. Very eye appealing.
2. Easy to use.
3. Awesome presets.
4. So much mixing diversity.
5. Brings life into the music (especially with Exciter Pro).
6. For how much it is, worth every penny.
I cannot think of a single draw-back unless one uses it with Ensemble Pro 5. If I could imitate Simon's voice from "American Idol", I'd say, "It's a YES from me".
