This might be related to how floating point values are represented in computers. Most CPUs have 2 "zero" floating point values +0 and -0 (one of the bits representing number is called "sign-bit" and can be zero (+) or one (-)). For calculations it doesn't matter.
It also might be related to the fact the the real value is +/-0.00001 and it just didn't fit on a display.
Profile files are to some extent based on MIDI format (it is quite possible that they are just MIDI files but instead of standard MThd and MTrk section names Kemper uses KThd and KTrk). This format is not encrypted (at least metadata part) and it is quite possible that Kemper might be ignoring sections which it doesn't recognize (I didn't check that). If that is the case it would be possible to sneak in some kind of digital signature. The other possibility is to find a field in this file which Profiler understands but is not using ("reserved for future use" field, or one that is not displayed anywhere in the UI, and doesn't do anything, or is no longer used) - Kemper is very old product - I'm pretty sure that if you'd poke around long enough you would be able to find such field.
But who would bother doing that if profiles are usually cheap? I join "BS detected" camp on this one.
... is to buy their amp.
not interested in big, loud, heavy, single purpose device which requires even bigger cabinet box, or some other devices, like load boxes. Wouldn't have space and oppotunity to use them to their full potential. Should I buy it and make usable for me (that is: profile...) and keep in storage? Makes no sense. Real amps played its role in history but new technology is taking the game to another level. You can't stop it - digital is just much more convenient, compact, flexible, bla, bla.
Don't get me wrong: they will still be around as boutique items, for people who just like real amps. There will still be people who will buy them. My point is that the world is going digital and if amp manufacturers want a piece of this cake maybe they should augment their products with digital goods (profiles, maybe license deals, like some do with AmpliTube).
I had no success with this converter (with RME Baby Face pro interface) either - same symptoms as you described. However SPDiF worked for me without issues when connected directly using coax cables into Komplete Audio interface. I declared this converter total garbage and moved on with analog setup (less cables, less power supplies).
In my opinion clock is ticking for "analog" and quite soon "digital" will be the only viable option for most musician (the gap in quality is almost bridged, and prices of digital will be only going down). Analog amps will join other technologies, like vinyl plates, which are reserved for collectors or just someone who would like to add some "vintage vibe" the their lives. This evolution can't be stopped, and happens very often in the world. DRM won't save it. Of course it is sad for vendors of technologies which are in decline but that's how things are progressing.
Kemper started this evolution by offering first true "tone replicating" machine, but it is clear that in a few year all major vendors will have something similar or modeling technology which will be perfectly capable of simulating or even synthesizing arbitrary circuit (Fractal is leading here, but in context of this discussion I don't see major difference between modeling and profiling). If not Kemper - someone else would do it sooner of later. I think the only sane way of rewarding amp manufacturers for their effort is to buy profiles directly from them (or maybe some merchandise). Sadly very few of them opt into this and sell profiles (Victory Amps is one good example - I bought their packs and enjoy them every day - Kraken, V40). Most people in this world are good and I'm sure wouldn't mind spending a few bucks to support their favorite amp builders, if they had opportunity. Why most amp makers don't sell their profiles?
Congrats! For me, too, Kemper was the best gear I've ever purchased. Saved me a ton of money, too. Didn't spend much on any guitar gear since 4 years. The search was over once I got Kemper.
Actually, that's not 100% true - I bought Stage recently 
Hope you'll like it. Have fun!
From my conversation with Christoph, he did all of the programming in assembly language.
This is probably true only for DSP part. If you look at crash logs / stack traces and diagnostics files many files are C/C++ headers, many functions are in Access:: namespace (maybe still remembering Virus times?), internally KPA uses sqlite as a storage for presets, profiles (embedded db, written in pure C). And KPA runs on top of some operating system (on ARM-based CPU), with sys calls, which would indicate that there is kernel / user space separation.
My tactic is to never use RM when profiler is in performance mode. I create rigs in RM but I manage performances on device itsef. Sucks a bit but works reliably. I lost a lot of time trying to find a viable solution, all in vain. Filed tickets to support about this RM issue months ago - no solution in sight.
Hej, sprawdź w System Menu. Powinnieneś móc ustawić parametr Performance Load na jedną z wartości: keep slot, slot 1 albo Pending. chcesz Slot 1. Na tosterze to działa, więc podejrzewam, że na stage będzie podobnie.
Just turn your remote around by 180 degrees.
You're welcome 
PS. This is backwards for me as well, but I adjusted.
I'd pay $666 for Kemper-Mini which would only have performance mode (a few mini switches to choose slots, + tuner LEDs, small screen to see the name of slot/bank), could only be edited from RM and had MIDI support + expression pedal input - just a small device for gigging. Size of Amplifire 3.
Check if reference pitch is set to 440Hz.
All right, I just spent 17 minutes watching a guy chirping on a guitar... Fascinating video!
OneEng1 I totally get your line of thought and generally it is very rational and logical, by "modern economy" standards (where growth and profit is the ultimate goal). However it requires one more factor: CK would need to _want_ to do it. Kemper is on the market for many years and I'm pretty sure that if CK was thinking like you outlined he'd not deliver Stage but something like above described Mini. They can do this any time, to be honest (and I'd buy one for sure!). But not all companies are constantly chasing growth and expansion, fortunately. Some companies, especially privately owned, just want to stay small, are fine with what they have, like to have great relationship with customers, as long as they can make a decent living out of it and have fun while doing so. Kemper had at least 4 - 5 years to create killer, low cost, made in far east, mass-produced unit which would bring them fat $$$, but they didn't do so. So to me it looks like as long as don't have to, they just don't want to do it, and they don't care about having even more $$$ as much. Their goals and values seem to be different. And this is fine and actually quite admirable.
The switches on stage look to me like the same ones that are used on Remote. I'm personally blown away by quality of Stage. All rotary encoders are from awesome looking and feeling metal. It can also shine as Christmas tree, but fortunately you can control intensity / hue of many LEDs and display.
This probably won't be very helpful, but I went through exactly the same exercise not so long ago and pretty much came to the same conclusions. Working with just dry signal + plugin set up to roughly similar tone seems to the easiest way and once everything is ready then re-amp using Kemper to render final tracks. This is especially useful for double-tracking, I learned - when recording multiple takes, mixing and matching, aligning copying and pasting.. Overall keeping in sync dry and wet chunks of audio is a nightmare - or at least it requires total discipline, which take fun-factor away from the whole creative process (at least for me).
I'm able to fit head and remote into official bag without any issues. I have unpowered head so can even stick expression pedal behind Toaster.
I personally think it looks great and classy. And to be honest it resembles more a fancy cooler for Bud light (oops, I'm sorry, for Franziskaner Weissbier) rather than a gigbag.
Check output section - headphones output has dedicated volume knob there.
I hear dead notes.
Are you playing death metal, by any chance?
i like https://www.tonewars.com profiles of SLO very much.
