I've always called it German Wizardry hahaha
I'm guessing the routing will be focused on the monitor and direct out although I'm not gonna rule out main outs too either at release or either down the road after enough feature requests. For sure Monitor out seems like the no brainer.
I suppose to people may want to have 2 different types of Kones available at the same time too . Greenback for this one and v30 for that one etc.
Not sure how Kemper is doing the Kone thing, but one way would be to have a custom IR made that makes a predetermined speaker (the Kone) have the same response as say a V30 or Greenback, in the same way a IR can make a FRFR sound like a V30 or Greenback. In the case of the FRFR, the assumption is made in the IR capture process that it's response is flat. For a non-flat speaker to work, you would have to take its response into consideration during the capture of the IR. In engineering terms, you would have to perform a A-B operation from the flat IR and the response of the non-flat speaker in the cab. You'd also have to take all the IRs in an environment that would not allow the cab characteristics to color the response (infinite baffle maybe?)
If this is the process Kemper will use, the implication is that they will be adding dual IR capability to the unit; one standard IR for the main out, and the second tweaked IR on the monitor out for use with the Kemper Kone.
I've been pondering the PowerCab and its magic for months now, but am not aware of what IR manipulation tools to use to get the same results. I'm a hardware guy, not too great with DSP engineering. But if I had mad Mathcad skills, I'd try the above to see if it would work. And I finally grabbed a few Celestion F12-X200's, which would be good candidates for such a device.
