There are a number of techniques guitarists use that depend on some form of interaction between the instrument and a speaker.
Can you tell me more about it? Which techniques do you mean? I only know about feedback as interaction, which i can get pretty easy with the control room speakers.
It would save a lot of trouble if Kemper sold or recommended a specific brand of Ethernet Cable.
they don´t recommend a brand, but you will find all the information you need to know in the manual under PROFILER Remote - cabling
...page 253 and 254 
check out this thread:
Erlend Krauser - Kemper Profiler Performance
post #39 contains a link to a profile ... 
from the manual p.238
While navigating Slots within a Performance via the PAGE buttons of the PROFILER Stage, or the left and right RIG navigation cross buttons of the other PROFILER variants, any modifications (e.g. loading another Rig, or cranking up Gain) are interpreted as editing, and will be retained until you move to another Performance. Don’t forget to storebefore you load another Performance, if you want to make those modifications permanent.
Performance Mode 238
✓As soon as you load another Slot from your foot controller, or foot buttons of the PROFILER Remote or Stage, any former modifications within that Performance are interpreted as temporary tweaks during a live performance and will be discarded immediately. If, for example, you had activated a booster in module B, or increased Delay Mix via pedal, any such changes will be lost if you switch Slots remotely. This way, you can always be sure that Slots will be loaded in their original, predictable state during live performances.
i have a toaster but my screen isn´t moving at all!
If i remember right, it´s because the impedance of the connection might change and this could lead to problems.
don´t know what you mean with "empty box"? download RM with Safari, find the download in your download folder ( it should unzip the installer for RM automatically) and double click the "rig_manager.pkg" to start the installation.
In this case you should add an POE Injector, i believe that´s what Burkhard pointed out several times.
i just updated Rig Manger to Version 2.3.9 (14936) and let RM update my unpowered Kemper Toaster to 7.05 without problems. First time i did not need to use USB stick. MacBook Pro 2019 OSX 10.14.6. Great 
it´s not contradicting:
you can edit all 5 slots and the changes will remain if you don´t change the slot with the remote, but with the page buttons or the navigation cross. when you done with all 5 slots you can store the perfomance, incl all changes in the 5 slots.
But, if you load a slot with a foot controller or the remote, you loose the changes you made. this we you can tweak a slot, but if you want to go back to the previous state, you simply press the slot button on the remote.
If all changes would be saved all the time, that would not make any sense to me.
maybe the manual helps:

that´s what helped me: try different picks out of different material and try to hit the strings from a different angle, exp. if you here the "click" only on downstrokes.
In the kemper, there is the parameter "pick" in the stack section to reduce or enhance the attack.
it´s fixed with the new beta 7.01
PROFILER Operating System 7.0.1.14852/14853
fixed: display color reflecting effect type correctly, if effect category selected via <PAGE> buttons
great to see things getting fixed so fast!
okay, i started the toaster again and the problem is gone.
i´m not here to complain, i´m very happy with my kemper, and i have no problem with testing beta versions , but i´d like to know: if we find bugs in the beta versions, where should we report them, here in the forum, or should we open a ticket?
I had no issues installing the beta with the help of the USB drive. But when i browse through the presets using the "page" buttons and the "rig cross" buttons, the screen colour is not following the category colour, like it does when i use the "type" and "browse" knobs.
I don´t like to use the "Type" knob, as my right hand is always blocking the sight to the screen adjusting it (sitting in front of the Toaster holding a guitar with my left hand).
That´s why i would love like to see that the 4 encoders below the screen could be used to change the effect presets in the future.
Hi Marcus,
i remember some people here couldn´t do no more overdubs and kemper support found out that they were using too much "dsp-hungry" effects at the same time. I know digital clicks from maxed out digital recording software. I think you should open a support ticket. 
I started a comment thread about rigs sounded different (in a bad way) after the newest update. Low end sounds fuzzy and undefined on high gain profiles. There’s a static sound running through the entire profile.
I wanted to roll back to the previous OS to troubleshoot this but Kemper took all the previous versions away for some unknown reason...
I hope they offer a roll back because I can’t hang with the new sounds and either can the guys local to me that know have the same issue since the update.
Sad state of affairs.
you´ve been told already twice in different threads to open a ticket so the support can send you whatever old kemper version you like to restore, so why do keep writing this BS again and again ("Kemper took all the previous versions away for some unknown reason..."??
Last time i checked i got between 2-3 sec latency from the kemper. I´m recording with pro tools hdx with adds 0.7ms latency, so latency is no problem for me.
You can reduce the latency of your recording interface by using a higher sample rate. For the Kemper latency i´m not aware of any possibilities.
