level loudness volume
Thank you for the questions – I'll try to clarify.
I do, however, recommend reading the manual as a starting point
The LVL COMP affects the main INTENSITY control only, and compensates the LEVEL, not the LOUDNESS (which is an entirely different metric). The compensation is valid for around 60% of the INTENSITY knob travel, outside of that range the signal dependent nature of the algorithm makes accurate level predictions pretty much impossible so it may be slightly off, depending what you throw at it. BIAS, DRY-WET and GAIN (including when using the saturation) are not compensated for.
The output mode "SATURATE" is a soft-kee saturating limiter that starts working at -3dBFS and that automatically makes that gain up.
The LVL COMP is actually "calibrated" on LUFS *assuming an input type that is modern music with a moderate level range of -20 to a maximum of around -10 LUFS* (so basically: stuff that hasn't already been flattened out). Outside of these ranges, behavior may still be consistent, but some degree of deviation is expected.
If you set the plugin up with this information in mind (so for example, when using BIAS, using it subtractively only), you'll find that peak as well as LUFS stay remarkably consistent while a lot of subjective loudness is gained. In some cases, we've observed the LUFS actually going DOWN while the loudness went UP. Which makes sense if you think about it.
The range on the INTENSITY is huge so that the plugin can work with a broad range of sources. The recommended range is 0...50%, and even that is a LOT. I typically end up at around 0.2 to 0.35.
If your input peaks are already full-scale – why not use the plugin before your other stuff when there's still dynamic range to work with? If the input has for example two consecutive fullscale words, and we add a third, your DAW may show a clip...which would be rather meaningless as compared to the "before". Lower level to plugin or output gain by 0.00001 db, done

Please see above, but LUFS is not LEVEL, it is LOUDNESS. A LEVEL compensation looks at the "electrical" levels. The idea of the plugin being to increase LOUNDNESS while keeping LEVELS the same or similar. Hence, it makes no sense to "compensate" for the loundness - what you hear is what you get.

I test it with a lot of disco and and dance, I can not confirm that there's a general issue. If the DETAILS of your audio are things you don't want to hear...then why boost them in the first place? Sounds to me like you're expecting something that the plugn isn't – which wouldn't be unusual as the plugin is a new TYPE of processor, so nobody really KNOWS what to expect of it
It brings out what's there.
Tried it also on some acoustic stuff and it becomes very unnatural very quick.
With what settings and what material? What exactly does "very unnatural" mean, or "very quick"? It's actually EXCELLENT for acoustic stuff IMHO. Try setting INTENSITY to .2, saturate off, no bias. If you CRANK the intensity then first, the weaknesses of your convertors and preamps may start showing, and secondly, yes, you may be adding unnatural amounts of detail.
"Operate the plugin with one control" doesn't mean that you can't set that one control to be too much
or too little
. That'd be a NO CONTROLS plugin
