It’s a feature that needs to implemented or fixed… So you know Make an audio track. set up an fx channel using delay or reverb. In your audio track use a send of that fx. Now assign that audio track out to a group channel. Pull the volume down on the group channel. the Audio track it self will be silenced but the fx send on the audio track will still be heard. That’s an issue Steinberg has known for a long time and still refuses to address… For the type of music I do which is reggae/dub that kills business becasue being able to do use the groups is essential and you can do drop outs and dubs with fx bleed.
