Use plugins that work with you, not against you
Back in 2005, while producing the Welcome To Violence LP with Gridlok, Keaton & Echo, we noticed something strange when using Logic Channel EQ. Even with less than adequate monitoring at the time, we heard the low end fall apart when applying a low cut filter to a kick drum. After testing further we agreed that it did indeed sound bad and moved on to using a different eq for low cut filtering.
Fast forward a few years and I discovered a way to test plugins and see what’s happening on a graph visually. Of course, one of the first things I wanted to check was this anomaly happening in Logic Channel EQ’s low cut filter.
Here’s what a 1k sine wave looks like with no eq added:
And with Channel EQ’s 30hz 24db low cut filter:
I dunno about you, but when I insert a low cut filter I’m looking to remove bass not add it!. What you’re seeing here is distortion, hardly professional quality. I’ve yet to find another digital eq that does this.

I find it appalling that it’s been over 8 years and Apple have yet to fix or even acknowledge this issue. Most Logic users trust this eq to be of professional quality and use it all over their tracks.
There are other avoidable things in Logic that reduce sound quality but hopefully the imminent release of Logic 10 will fix them.
Stay tuned and feel free to comment or ask any questions.
