Well, if this enables recording of MIDI-wah streams, generated by analogue pedals connected to the Kemper, alongside DI tracks, it'll be what I've been asking for for 2 years, and I'll be absolutely-stoked.
For those who haven't thought about it, it means one would be able to re-amp whilst also sending the original wah movements made during recording of the DI track.
In addition to the re-amping process, this would also help creating MIDI backing tracks controlling Kemper. I'm using Cymatic LP-16 backing track player to switch present along with the click track. If I understood correctly this new feature, you could record e.g. volume swell and lowpass pedal movements home and send that data from MIDI device to Kemper live. Earlier such volume/wah curves were needed to be created manually in DAW.
