Ok, thanks gentlemen. Not the news I wanted to hear, but it's what I needed to hear.

I think this is the last year I'll buy BIB then. It's a great program, but I'm suffering from upgrade / new features / new bugs fatigue. Call me a reactionary ...

It would be great if in the future new RTs are modular, and so can be used in any recent-ish version of BIB. Just like when you get an expansion pack for something like Addictive Drums or EZKeys, or new loops for Acid. These work in the old applications. Their business model is to sell the razor cheap(ish) and make money on the blades.

With PG, seems you have to buy the razor each time as well. This probably makes sense for PG, but doesn't work for me.
