I just tried 4KD GC and couldn't get it to compress the audio... Even if I bring the threshold all the way down, with a fast attack it doesn't really do anything. The sound comes down, the GR meter "says" it's compressing but in the end, if I compensate the level back up, it's not squashing anything.
The 76D works fine. The G2500 demo works fine. The FATE doesn't do anything either and the Snap doesn't do anything either.
I don't remember this happening before.
I'm on 1.3.600 with the settings recomended for the G2500 (<up> 1 </up> and changed PROG RATE)
