Several KPA users suggest you use a mono signal "Stack" on the SPDIF out when you are doing a final take or re amping and using the delays, reverb, etc in your daw on a dry Kemper track. This does make sense as the Kemper reverb is probably not as good as that plug in in your DAW....or the delay. I believe you will hear the Kemper effects when you are playing, so you have the right feel....but the "stack" setting will give you the Kemper amp sound in a mono track without stereo effects, or any effects...then you can simulate them, or make them better in your workstation. Does this make sense to you?
So what do you do. How do record you final takes?
