Hi Kevin, I’m listening to the latest Soundcloud version, I think. You mentioned a bandcamp version, but I didn’t see a link. Got your PM too. The drums on this version sound a lot better, I think. I probably wouldn’t make a remark on it. You could continue to experiment with it. The bass still has wrong notes to my ears in the same section; you should check it carefully. Don’t ever get me wrong; your stuff is great, so I just want to help.
For the loudness point, certainly Ian can help, he knows how to use those tools. I got carried away and wrote a reply to a thread on mastering which would encapsulate all the advice I could give, which is amateur at best. That is here: Computer für Audioanwendungen - WaveLab - Steinberg Forums
I’m not so comfortable posing as an expert. But I don’t mind sharing what I’ve learned.
Keep them coming. And keep supplying those lovely avatar pictures!
