Vortex Sound Research

I have the Crave and Wasp and want to add either Cat or Pro-1. Cat is my first preference because of all the demos I heard online, the sounds of the Cat give me the most pleasure.

I was looking around and noticed people saying that Cat is too buggy. I could not find any info about whether firmware updates fixed the bugs, at least some.

Does anyone know what the situation is with this? Thanks!
