So the bad news is I'm short on time this weekend.
The good news is that my first impressions are 'absolutely fantastic'. Thank you very much to the team that made this. I've had my Kemper for many years and it's incredible that it's actually still improving each year since the time I had it. This does not happen with most other electronics and I'm very grateful that it's the gift that keeps on giving.
I have been politely asking for an editor for many years and I am over the moon - the layout for doing this stuff on a PC screen vs going through 6+ menus on some of the delays just makes so much more sense to my brain. For the guys that don't want it / need it, no worries. For me, this has given my beloved green box another massive boost in the usability. We are all wired differently and this works for me better than the front panel. Strange but true.
As I use it more over the coming weeks I'll no doubt make some suggestions but so far, so good
One thing - I followed the instructions (latest software via USB and then installed Rig Manager). Reboots, cable fiddles etc did not help me - the Kemper worked, and I could see my local library but the Kemper just would not talk to the PC. I unistalled Rig Manager and re-installed. It then worked without any further problems. Thought I'd share in case this helps someone else.
