These are my thoughts exactly. I've just gotten "average" in my mixing abilities, after about a year and a half of lots of trial and error. I've gotten to the point of having the multi-track files downloaded, imported, organized, gain staged, then...boom...it's time for another Feedback Friday of a new song. Seems there are some PLAP Academy members who are really, really efficient at this stuff, turning out a mix or sometimes mixes of the song of the month, before I've had time to even start on one.
As you said, working on a 8 or 16 or 24 track song, versus one that has over 60 to 70 tracks, those of us with more to learn with less could benefit huge in this Academy.
