Hey Elfredo... thats a pity.
Sure there are OS updates to extend the basic original OS supplied at release date, but I dont know of a single 'digital' product that does not get those....
In any case, you tried it and it's not for you.
But honestly, I don't really believe that the KPA has a 'high price' for this level of product... reason being, that if you were to typically buy just one of those top end tube amps that the KPA replicates so well, its likely you would have spent more than this device costs by far - and the KPA can handle hundreds of really cool sounds.
Many boxes out there have just a few 'killer' sounds and the rest just fill the box with rubbish... which means in reality that in those cases price per 'sound' can be really high. But if you use say just 100 sounds (and they really are in there by default - adding your own simply makes those sounds an even larger sound base to work from) then in my case the cost would have been just £11.70 per sound... and thats a real bargain. Add more amps from profiles on the forum and down comes the price per sound dramatically which in my opinion really makes the unit a veritable bargain longer term.
I can honestly say that apart from one 'odd' noise from the KPA I have never had a crash, burn or anything else happen to mine but I have read on this forum that some guys have 'suffered' badly from that. Clearly you are one of them - but maybe it could have been a faulty unit? I would have certainly spoken at length to the Kemper support team about my issues and problems. And I would have expected definitive answers. But maybe they could not be solved to your satisfaction at this time.
At least you gave it a go and I guess it did not work for you and thats all anyone can ask of any potential user.
Sorry it did not work for you and good luck in finding a replacement that works for you.
