Further, there are people that don't use an editor at all (most I suspect). Certainly I didn't use an editor with my tube amp rig
Do you only use one rig in your Kemper? You'd probably need to have multiple tube amp rigs to copy what you have in your Kemper.
I've been hoping for an editor since I got my Toaster in 2012 so I guess I am willing to wait a bit longer for Kemper to get it as bug free as possible.
