Gday bpolits.
I work with the same interface as you and I think I understand your issue. It looks like you have a drum kit set up with various mics on the drums is that right? And your’re saying that you can still hear the inputs when recording/playback? I have different presets in Cubase depending on what I’m recording…So if I’m using 8 mics for the drum kit I’ll select the preset that I have saved in Cubase Vst connections that has 8 inputs and if I’m just recording guitar or vox for example I will just select the preset that I saved for that which is the two front inputs on the interafce. Not sure if I’m understanding your problem or not but hope that helps.
