The cracking is coming from the high end, and the only when to get it to disappear is to cut out the high end completely, which is clearly not the right way to go about it. It goes away very-slightly when I just use a reverb as a send/return, but this again, is a pretty crippled way of working with Ableton.
Some people have told me that it's my sound card/driver, but I'm using CoreAudio on a brand new Macbook Pro, so I would think that would work just fine.
I've messed with every last parameter and can't get the flippin' effect to work with me, so if anyone could throw some suggestions at me or help me out with this problem, it would be GREATLY appreciated. I can't make tunes until I get this figured out, so the quicker the better.
Thank you.
