Being a Kemper user for about 6 months now, my impression is that they don't release something till it is darn good and ready. You don't see a lot of issues popping up on these forums with things. Sure, there are a few but not many. Thing is, an editor will be awesome. But the fact that Kemper makes a small market product, you have to figure there are a 100 Pod users for every one Kemper owner. With the size of the company, it's certainly understandable if it takes a while as they just don't have the human capital to do everything really fast We finally got performance mode, long wait. The result: awesome. The same thing will be true of an editor and the dedicated controller. We finally got pitch effects, the result there, awesome as well.
Consider too, that they don't get any more money from releasing updates that make current users happier. We already bought our Kempers. The only profit to be made from new features is the incentive to attract new buyers.
Kemper's biggest obstacle to growth is it's price point, and the difficulty to advertise. Think about it for a second. They claim, "you can sound like any amp, and even copy your own amps." When I first read their advertisement I was like, ok, another modeler that talks about sounding like any amp, which is what every manufacturer of modelers has been saying for over a decade. When I read the "you can profile your own amp" I was like, great now I can make a 2 dimensional lifeless copy of my budget amplifier instead of a 2 dimensional lifeless copy of some of the best amps on the planet. My curiosity at why the thing was so darn expensive led me to do a little research and discover why. Which it turn led to me making the best musical purchase of my life. However, I wouldn't be surprised if the Kemper organization is on a tight budget, because relatively few guitarists have even heard of Kemper, let alone own one.
