I just want to say a huge, massive THANK YOU to aj113
and all you guys!!!!!
I went back to the drawing board... and did the best mix I could. Again. I'd got too locked into "mixing into the master bus compressor". Because I read it somewhere! Crazy!!
There's no separating mixing, getting the best mix you can... and the fine art of Mastering...
So, like aj113
originally suggested, I reduced all levels, and mixed a 16/96 WAV (with nothing on the master bus), then put it in a new blank project, using one of the more gentler iZotope settings ("Classical 2") and a tweaked Multiband Compressor. Then finally "normalised" (I'm so UK spelling...) I mean, the mix wasn't bad as it was... it just seemed to lack... lack some "sparkle?". No, that's not it, it just sounded a little flat. Not simply reverb, but something a bit more like an Exciter??? This seemed to improve it, anyway.
And the waveforms at least *look* better...?
The final mix (I had to go back and fix all peaks, ride the faders on the vocals, and some hard piano velocities), and then the final master are below...
It drops off after 3/4 of the song, because I haven't recorded the Bridge vocals yet....lol
I've neglected doing the washing-up for this. But it was worth it! (So rock n roll...)
