I have searched the forums and other web sites for the last hour or so and cannot find any confirmation of this behavior.  Hopefully someone can confirm this.  I have done a reinstall after building a fresh system disk and I am still seeing the issue.

I was attempting to compare the PC4K with Cytomic The Glue.  I put The Glue in the FX Bin for the Master bus and used the PC4K on the Master bus.  I was very careful to make certain that both were never active at the same time.  

I noticed that the PC4K starts compressing at a lower level than The Glue.  I had both compressors set at the same Threshold, Attack, Release, Ratio and Gain.  The Glue was doing its usual job of 1 to 5 db of gain reduction.  The PC4K, with the same settings, was kicking about 5 - 12 db of gain reduction.  

Just to confirm this, I removed The Glue from the FX Bin and listened to the track all the way through and noticed the peak for the Master bus.  I then set the threshold for the PC4K to .3 db above the peak for the entire track.  By doing this, I believe the compressor should never have kicked in.  Yet, when I pressed play, the PC4K was doing about 1-6 db of gain reduction consistently.

Can someone confirm this behavior and/or point me to a posting/article/white paper that explains it?

Thanks!

Michael

I've yet to see any detailed info on any of the Pro Channel elements.

Maybe that's the reason nobody has replied yet.

Sorry I don't have Glue either so I can't help you at all.

It does however baffle me with so many 'accurately modelled' SSL style units out there how much they differ between manufacturers.  It makes me wonder what 'accurately modelled' even means.

Wow, how strange....

 Have been playing around with PC and last night and ended up banging my head against the wall. Was just about to post and saw this thread. 

 Anyway, I suspect Michael, that my issue is basically the same as yours. 


Let me simplify this. 


On a bus, routed with something like a metronome or something that has a consistent peak level (Make sure the bus is peaking BELOW 0db  i.e. -5)  activate the PC4K. 


Set threshold to 0db


WHY IS THE COMPRESSOR WORKING?  to my mind this does not make sense, I hope someone can explain why this might be and that it isn't another PC bug. 


 Surely until that bus content reaches 0db, the compressor should not be working. 


X1 Power (by Scott R. Garrigus) States: "Set the Threshold. Threshold determines at what amplitude level your audio data will start being compressed. When the amplitude of your audio data reaches the Threshold level, processing will begin." 

 That is not what I am seeing...

This is exactly the same issue.  I don't care what is being modeled, unless they have stated clearly that they used a defective unit as their model, threshold should work.


I have opened CWBRN-6232 for this issue...let's see what they have to say.

Yeah, this is strange. Looking forward to the explanation on this one.

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?

 What the Hell???  

 Surprised all the PC/X1 bashers are not all over this like flies on s**t


I mean come on, is this not the most basic element of the PC4K or any compressor? 

 * Totally baffled *

  Well, FWIW, I take those two compressors about as seriously as my dog's make believe furry animal play toys... the idea that they might not work correctly is hardly anything to take too seriously.

  Make the best of it and have fun with it or don't bother using them... that's what I say.

  At least they aren't painted black.


  ProChannel, Boost 11, LP 64 EQ and LP 64 Comp.... It all seems like it was designed to make you want to go out and buy some Wave Arts or Izotope stuff.

If they don't work ...then there are loads of others that will.

Are you kidding I know this but: I like the ease of use of the PC, the fact it is right there. Oh and did I mention it was one of the reasons I bought X1. 


 Oh God. 

"I like the ease of use of the PC, the fact it is right there. Oh and did I mention it was one of the reasons I bought X1."

Well then, you got something like 80% of what you wanted.  :-)

I paid my $99 bucks and regret ever opening the box. :-)

I should have just put it on the shelf and started counting down the days for X1 Expanded to be released so I could upgrade.



Just make the 4k compress something....  that analog stuff never really lined up with labels on the face plate anyways.

It's at least as good as any other compressor out there, plus it's right there and easy to use.

all the best,
mike
