Haven't we been used to combine lots of gear to achieve the sound and effects we need for decades? Haven't we the same today, if we need to? If you need pitch effects but still are happy with the sound and other features of the KPA, couldn't you just find a pitch shifter that you like and put it in front of the KPA? I mean, seriously, the strength of the KPA is the amp profiling, the amazing reality of the amp sounds. You can't get this in any other gear in 2013, as long as you don't buy the "real" amps and cabinets ... and even then you'll still have to add your effects in some way.
If someone serves me some really good Spagghetti Bolognese, but for my taste some Parmigiano and some black pepper is missing, I'm free to add as much as I like. No reason at all to refuse the Spagghetti and go for a can of Ravioli.
PS: When you bought the KPA, the pitch shift effects still were in public beta. Of course it's not good to still have a problem after the release version was published. But still I think it's not valid to call it unusable. But that's just my own point of view, as always.
