I posted an earlier question about my music sounding flat coming out of professional speakers. I wanted to add the following: My sample rate is the same as on my mac so that isn't it. I am using EQ ZISO and filterZ. In my internal mixing mode I have enable auto gain with ozone enabled and a headroom of -3dB. In my external mixing mode I have enable auto gain limiter/boost type ozone enabled with a headroom of none. Could any of this be the problem. It's not the speakers. It is the way music is coming out of my computer.
