I don’t know if they have plans to update the units anytime soon, but if they do, I think they need one mono send/return that can be mapped anywhere before the amp, and a second stereo input/output send/return that can be mapped anywhere post Amp.
I’m not a fan of many of the Kemper effects, so for me to currently stay stereo, I go out of the Kemper L/R outputs into my stereo effects and then to my studio monitors. Problem is, I can’t record my stereo effects into Protools as the Kemper signal is fed from SPDIF.
I know it’s better to add the effects post recording, but I would like the option. Plus it keeps everything stereo, making it able to Mix Kemper Stereo Effects and External Stereo effects.
