Sorry, I still think the attack and release controls are 0->127 = fast->slow.
Try this to hear the effect of the attack and release controls:
- Get some content with sharp transients playing (rim shot, snare, etc.)
- Set the ratio to 127 and the threshold to 0 to make the effect as pronounced as possible
- Turn the Mix to 0 which is 100% wet
- Set both the attack and release to 127 and listen for a bit
- Set both the attack and release to 0 and compare
Which attack and release settings sounded more "extreme"?
With both attack and release set to 127, the effect is much less pronounced which means they are
slower. With both controls set to 0, things get more squashed and possibly distorted, (albeit less distorted than it used to be!) which means they are
faster.
The bottom line is that compressors will sound less compressed when the attack and relase are set slower and more aggressive when those controls are set faster.
That's my story and I'm sticking to it!
