Alex - What can I do if I already have the most up to date drivers?! You imply that I haven't tried everything! The glitching happens even when I take out my sound card and run through the on-board sound.
I've downloaded the Fabfilter Pro Q demo version - it works
like a DREAM.
SURELY, after everything I've tried, this shows that the problem is the Pro Channel EQ. It shows that my set up CAN handle frequency sweeping like it should.
It looks like I will be staying with the fab filter.
But Alex - I appreciate all of your help. I wish you could literally come to my house and sit at my PC and have a go at nailing my issue!
Clintmartin - Fabfilter, on first impressions, is great! So much control. I love being able to double click a new node in. I think it doesn't sound as natural as the Pro Channel EQ, though it still sounds great, but I mainly make electronic music which shouldn't be an issue.
Mettelus: Yeah it's a nice video - I actually learned a couple of bits from it.
