I actually purchased a Quadra Thru. Unfortunately, none of my RME interfaces provide enough power for it. I still think the option of switching the Kemper would be much more efficient, negating the need for an extra unit.
I speak from personal and recent experience with Kemper regarding a MIDI issue I had with my gear. A ‘simple’ option added by Kemper would have solved it.
While Kemper making the change may be the most elegant solution for you, it will *not* happen. Not for one use case in 12 years.
I don’t blame them.
It may be a simple change compared to a new effect or what have you, but any change affects all users, requires some level of testing, and in the case of added options necessitates updating the manual and it’s translations.
If you haven’t already, I’d be inclined to contact MIDI Solutions. John Fast has forgotten more about MIDI than the rest of us.
