Hi guys, even though I have been producing for years, I still have trouble with the mixdown of my tracks, I have recently sent a track to a label and gotten the response, that the track is quite good but the quality is lacking. (I can post the link if you want to hear what I am talking about). Especially when there is a lot going on in the track, I can't get them to sound clean without heavy cutting of frequencies, so I must be doing something wrong. Can anyone give me links to good sources about mixing, or give me some advice? For instance, how do you mix two components that use the same frequency range, without loosing power and punch? What's the key of mixing a really good clean track? So far I know you have to be carefull with the range from 40-400 Hz, cause that's where it starts to sound muddy, but when mixing guitars for instance, how can you keep the nice low end info of the guitars while cutting this range? I seriously think, that's my biggest problem right now and I really need to improve. Please, be as specific and detailed as possible when posting, thanks guys!
