You lost me with the above. It seems to be a wide open statement?
Perhaps throw out 48 raw wave tracks that comprise a song, and using only stock Cubase plug-ins focus on making the “best” mix? (Would have to list the stock plug-ins so there is no misunderstanding) That would be a bit more focused IMO. But if you include all production and elements prior to mix plus all the stock synths, I’m not sure what is gained?
I’m currently working on a pop song where my total hours are at 154. (composition, tracking, mixing) I’m guessing I still have another 30-50 hours before sending it away to an ME. So “making the most out of it” is too much investment for myself. But if someone threw up 48 raw tracks and this was a mix contest using only stock Cubase plug-ins, that IMO would be much more practical. I think there are some forums that focus on this on a normal basis.
