Here is INIT. So what is all the phase distortion Tim? That looks worrisome.

Thanks Plexus but I mean the phase the second plot down in your original post......It has a zigzagging which seems to mean somethings up with the plot. A Latency issue would explain this though as Stedal said

Got it. DDMF confirms this is a problem with PluginDoctor and fix is coming. I will re-do and update once I get the fix.

hey tim, that´d be great - the fastest attack i´m using is 10 anyway so there wouldnt be any downside for me ;)
i´m using logic 10.2. on osx 10.9.5. with nebula 4 (dont recall the version but can add later if needed)
I've added the extra n2p's for Now i've only made alternatives for the L-R versions.

Inside the zip i've wrote this-

These extra N2p's were created for lower cpu. This slightly effects the attack time and distorion character.
For getting faster attack times, use ahead parameter.
For superior acurracy use the normal presets in the original release.

Here's and updated version using PluginDoctor 1.02 which corrects the phase problem. I also added another column for the L-Bus+Pre which is both in parallel, pre after L-Bus.

Hi Tim!
Does it make sense to reduce dsp buffer of nebula with your compressors libraries, while they already have a little RTE ( 0.045 ms). Or like you sad before, comps programs configured for a specific buffer, because of EVF? And if so, what the best of it, 512?

hi

No need to touch the buffer. Going to low can truncate kernals on eq's and reverbs. On comps the buffer won't effect cpu that much as it's timed. It does however change the gui behavior.

cheers

Hi Tim! Thanks for clarifying)
This applies only to your libs or all 3d party devs?

And, please, remind me which buffer is default?

Hi Tim,
The LBUS based on 384 D*x VCA engine or the new THAT VCA X-Logic?
Thank's)

my comps aren't affected that much by changing it, except change the speed of meters. Best just keep it at 1024 or 512 in general.

Remember you need bigger buffers for longer kernals like reverbs etc , not only does it lower cpu but can stop truncating the tails.

The comp is THAT chip

Ok, understand) Thank's, Tim!

And last final question.

The new and old Lbus have different frequency response and dynamic behavior.

Look 17.10.2017 ver.

and 09.12.2017 ver.

That 5 hertz low bump in the new one, creates a DC Offset.
Is that normal or a bug?

Also because of this bump, Lbus sounds a bit aggressively, in comparison with others G bus comps.
But yours, sound and behaves most closely to the hardware and it would be nice to know is that bug or feature of the sampling unit?

Thank you!

Its saturation from the kernals in the lows. This is why it will offset, in other words a even harmonic. I will look again but I think it should be more accurate

Tim, please look at the waveform distortion caused by DC offset (Dynamic section of PluginDoctor screenshots) in Shibata's post.
I suppose it's not a nominal behavior of comp's pre.
