had the same prob when I bought the CL few years ago, and with the updates/repairs CL it didn't fix that completely.
Windows 7, 64bit with Asio drivers.
personally I find the Nomad limiters better as they have attack/release controls, fantastic present from Cakewalk !
Allthough Concrete limiter sounds great at first I would only recommend it for synth pads and anything without a beat in it.....to my ears CL takes some life out of the mix (dynamics).
That's just my opinion and I know many are very happy with CL.....
Craig, just thinking often I wish for an A/B (C,D...) tool in Sonar.....sometimes I want to compare a few changes to the project quickly and an overall A/B button would be very helpful there.
thankf for all your tips/tricks and great vids :)
