Hehe... I always giggly seeing DB's replies to things like this with "there are no rules" in his signature...

I know where your'e coming from Jay, cos it is so so so hard when you have a sound that you want to sit by itself at points and then be part of a full mix and when you drop bits it sounds all thin and blah blah blah etc...

Dare I say it after the discussion recently in the techno forum, it's something that I've struggled with a lot with guitars, 'cos as DB said there rightly, guitars take a hell of a lot of space in a mix, and (personal opinion, so we'll not go into that here ) I like guitar sounds in techno, and I like dropping to just a thrash guitar, but that if it's eq'd to fit in a techno mix is nigh on impossible to get it sounding right by itself. Of course that could be construed a bad sound choice, but...

Anyway... rambling back, it's always seemed to be that things like automating eq one of those "rules" (I've always been told it's a rule not to) that's just dying to be broken for creative purposes, but then when you do it is very hard to tame it and get the balance back...

I've done things where I've dropped frequencies out of one sound subtly and replaced them in another using shelving eg, but that's kind of like a filter with no resonance really anyway, and again can be hard to get right....
