[quote=FoB Mario]If I for an example pan my mono track 30% right, and then route it to group stereo will it effect my pan?[/quote]
Yes. The mono track will still appear 30% right after it gets into the Group Channel. However, if you adjust the pan control of the Group Channel, that will affect the stereo image of any and all mono and stereo tracks that are assigned to it.
[quote=FoB Mario]Is it ok to group mono tracks into group channels? when or what not? If i group a lot of these panned tracks to same group channel will it folio the pan of group channel or individual track channel?[/quote]
It's always OK to group mono tracks into Group Channels. If the tracks you're assigning to the Group Channel are panned, they'll appear in the Group Channel in their original panned direction. However, as I said above, changing the pan control on the Group Channel will affect the stereo (panned) image of the source tracks, mono or stereo alike.
[quote=FoB Mario]Should I use stereo or mono in group channel? Whats is the difference? I get a lot om hum sound in my mixes when i use for an example h-delay and JJP vocals Mono/stereo in my mix..[/quote]
If the Group Channel has a stereo configuration, then use the stereo versions of your Waves plug-ins. Conversely, if your Group Channel has a mono configuration, then use the mono plug-in versions.

I'm not sure what's happening there. I would get in touch with Waves to see if there's a solution.
