D8Bridge and Plugins

[Studioa]

Could someone explain to me how to control plugins with D8Bridge. I have Samplitude Pro X Ver.12 I will load plugins in the first two slots in Samplitude mixer I then switch the D8Bridge too plugins, I can see them both on D8Bridge screen.
How do I go about setting the controls in the D8Bridge to edit the plugins. I cannot find any documents to do this.

Thanks Studioa
