Falcon for $100 is a steal! $100 voucher to spend in the UVI website will get you a couple
very nice expansion packs for it. I can't think of any reason for someone NOT to do this. Of course, I did my upgrade when the deal was $250 for the upgrade from Falcon - Avid version. But I also got the $100 voucher. So there's that! And I don't regret it one bit. I use Falcon ALL the time. And I love doing sound design with it. It is so multilayered and creative with what you can do.
The only thing I wish I could do, and don't know how, is use Lua to create a really cool looking macro interface for the sounds I create. I just use the stock one because I don't know thing one about Lua scripts. I wish I could create something cool like some of the expansions have.
