Midi settings when using two kemper together with one remote

What should all the midi settings (in both kempers) be that I can run two kempers together with one remote?

I can get the some parameters to change in kemper 2 when touching kemper 1, gain and basic soft knobs.

Is it even possible to get anything else changeing together?

Don't really understand anything about midi.

My biggest problem is how to mute both kempers when you push tuner from remote.

Thanks!

I think I have some problems with the setting, since when I switch tuner on, only my kemper 1 will go on tuner mode.

Thanks Kempermaniac, I'll check straight away.

How do I get rid of latency between two Kempers?

On both Kempers you have to use Mute Signal option (Soft button 1) when in Tuner Mode.

Yes they are both enabled, but the kemper 2 doesn't even go on tuning mode
