I currently use groups such as toms/drums; guitars; keys; bvs; lead vocals etc - average stuff. But I also use a group called “phones” which I put all those groups into just for tracking vocals and live drums - so I can lower the volume of everything easily for the singer and drummer. I have felt that somehow subgrouping like this affects the sound of the instruments - not sure if this is real or just a perception but anyway; I have started experimenting with VCF groups however this seems a bit more complex than I expected - I understand the flexibility but they are not as easy for me as groups.
What’s your opinion of groups vs VCA’s? What are you using and why? Do you think there is any sonic difference? What do you use to create monitor mixes or perhaps you don’t need to?
