Whoa whoa whoa... Hold on a sec here.   Are we saying that this issue is correct? the threshold control is broken? and no-one has noticed it?

Whoa whoa whoa... Hold on a sec here. Take a closer look at that "Threshold" knob label. The PC4K doesn't have a "Threshold" control; it has an Input level control. Check the Help. It works completely differently from a conventional compressor. Basically the threshold is fixed, and you raise the input level of the signal to make it "run into" the fixed threshold. You can't set it by the numbers and compare it with a plug-in that has a variable threshold unless you do some math.

Whoa whoa whoa....Hold on a sec here. People jumping to hasty generalizations about a feature they don't understand or know nothing about... Just another day on the Cakewalk forums.

The PC76 U-Type Channel Compressor does not have a dedicated threshold control. The PC4K S-Type Bus Compressor does.

Oops. My mistake - mixing up the two. Sorry guys.


I'll have to check the right compressor , and see if I can replicate an issue. Right offhand, though, it seems to me that compressor thresholds are a little "soft" in terms of where they start working and how hard. The Attack parameter can have a big impact on that. This is one of the things that makes different compressors sound different, right?

I knew you was mistaken... cause I have some real ones to look at.

:-)

In any event...

Once the threshold is set low enough to recognize a signal the attack parameter will certainly have a lot to do with whether, if and when a compressor kicks in,


If you set the threshold above the contents peaks the idea is that the compressor will not kick in at all... so attack settings shouldn't mean much.


I'm guessing the OPs observation has something to do with VU meter emulations, vague parameter indicators on the knobs, and a response to peaking in the actual compressor.


all the best,

I'm guessing the OPs observation has something to do with VU meter emulations, vague parameter indicators on the knobs, and a response to peaking in the actual compressor.

But who knows when the concept of 'accurate modelling' is applied to these emulations?

I personally can't see a purpose of comparing one emulation with another in this way, once you learn how to get the required behaviour from any one of them at any given settings you should be all set.

A better test would be to see if the signal is affected with the threshold set at zero (or above any peaks at least) or whether it is merely being errantly indicated, rather than comparing with another plug in purported to represent a similar real world model.

I wouldn't mind betting that Mike's REAL units even differ slightly between them.

Oh boy..here we go again....

Define "Accurate Emulation"

Whoa whoa whoa wo... what's up pussycat?

well, threshold shouldn't be a part of "Accurate Emulation" 8-S
