This is a really significant upgrade to a not new piece of guitar equipment! Happy customer.
Recorded a quick loop with the Profiler looper, then just jammed around with some of my favorite rigs, tweaking the parameters in the Rig Manager interface. Enjoyable. Noticed when I handled the EQ that I wanted the familiar 4 knobs next to each other - seems like ear-tuning those familiar EQ parameters is more intuitive with tactile rotation than with mousing/scolling. So I just reached one hand over to the Profiler EQ and kept my eyes at the computer screen. Very intuitive.
I like the darker theme (File -> Preferences -> Brightness="Black Hole" ), and it seems that the browsing aspects (which were a part of old Rig Manager) are more performant now, with less loading times.
Thanks to those who worked on this, and to the company for prioritizing this, and also thanks to the users who keep uploading to Rig Exchange. It keeps growing with 14600+ rigs at the moment.
EDIT: I found out about this news because someone told me about it, otherwise I mostly just use the RSS feed for the "announcements from Kemper" subforum. I'm guessing that others will be missing this announcement for the same reason.
