This statement is on the Kemper Profiler web site:
"Traditional MIDI based foot controlers are also supported and pretty much every parameter can be controlled."
I have had a Profiler for over a year, and in order to be useful live, required the purchase of a pedalboard to control it. To now change course and either require me to purchase a lesser pedalboard to get a significant feature or continue with my pedalboard without the feature is why I have a complaint with the policy, regardless of whether I had met Christoph or not. Kemper has promoted (and still is promoting) the use of 3rd party products with the Profiler, now to the possible detriment of their customers, in my opinion.
