Kemper Profiler MK 2

Sine tones or pink noise work best.

Not for dynamic behaviour. Unless you mean several at various different levels, and both single and multiple (meaning simultaneous) sine tones to generate IMD, and so on...

You could modulate the volume of the sine or pink noise sources over time, and that would cover the dynamic side of things. Many ways to skin the cat.

well a great amp actually is great BECAUSE the same note played twice is NOT the same. So assuming the amp would input > output always yield the same output given the same input is WRONG for tube amps anyways. The whole null test bingo is BS if you ask me. Ever played a cranked 100 watter having your guitar pickups go berzerk with feedback and the room shattering? Then I'm sure you know what I mean.

That's mainly caused by time constants (which a model/capture can definitely replicate) and by environmental variables like temperature and voltage fluctuations, nothing magic happening inside the amp.
Do you rely on that stuff to make your tones interesting? Then your playing must really suck!

Just when I thought this thread was dead

 

[BenIfin]

I think when the MK3 Kemper drops this thread will still be going

Once the MK2 Profiling lands and is tested, and we know how good or bad or unchanged it is, this thread is going to challenge the "Line 6 Helix" Master Thread at T.O.P :)

Just when I thought this thread was dead

It’s really something
Hoping ,we can cover the migration and mating patterns of the South Pole penguin in depth next

 

[Orvillain]

Hey guys!!! Remember that one time @OneEng tried to make an argument, and failed miserably!?!

OMFG! That was soooooooo funny right!!!

Could you explain me what's the difference between those two things according to you?

Sure. The thing to keep in mind is that K-Weighted loudness curves exist to normalize how humans perceive volume; these are f.ex. used on TV and radio to process audio so everything sounds more or less the same volume across the frequency spectrum.

The issue with using loudness-adjusted measurements for accuracy testing is that how humans perceive things has little to do with how similar two audio signals are. As you mentioned, LUFS highly favors the mid- and high-end, so low-end inaccuracies will have little impact on the resulting measurement, even though those differences will be completely audible.

But wait, we listen to signals with our ears, right? Problem is, the fact that humans perceive bass as less loud than treble at a given level doesn't mean bass goes away entirely. The bass region for two different profilers could measure the exact same in LUFS, yet sound wildly different.

As i said, using LUFS is a good starting point, but reducing modelers comparisons to it is a very flawed approach IMHO.

I'm curious to hear that now...

Just do a quick search on his YouTube channel I like how Leo bothers to include these clips in his shootouts.

So, apparently "MKII" profiles can only be created if your Kemper is hooked up to Rig Manager?! You can see @GuitarJon 's heart break in real time as he explains this.

 

[Orvillain]

That's actually crap. Super super super dogshit. Needs Rig Manager? Eat a Mig Ranager. .... I don't know what that means, but the feeling is there.

 

[Sascha Franck]

That'd be the new definition of a stupid move. If anything, it was just great that all you needed to create a profile was the Kemper and nothing else.

This turd is turning out to be a clickbait goldmine. Ugh.

Disingenuous, maybe, but NAM and Tonex needs outboard processing to create higher rez captures/profiles. NDSP allows pure self contained capturing but is not quite in Tonex or NAMs league.It's obvious, this is how they maintain the same internal component hardware, but are able to use outboard processing for horsepower not actually in the unit.

 

[AFKAEjay(retired)]

is simply less accurate than a quad cortex,

Not to my ears, and I have them side by side.
And in 10 years of profiling my own amps…they always popped out great.
And 15 years of YT blind tests where people can’t tell A from B…those “eartests” made the mark also.

So “simply fails audible” can’t possibly be true in all cases.
Maybe certain amps, idnk. And sure there’s vids where it is audible, but that’s also the case for QC, and for both 10 others where no one can tell amp from capture by ear.

Agreed but all the items you listed are significantly cheaper and not necessarily meant to be "in the box" ready.

But you could view this as a positive solely because it means maybe it will bypass the Kempers dates profiling and actually be better? I mean if it is as good as NAM. BIG IF. and you could load it on to something like a Kemper stage with all the effects and switching.......I think that would be pretty ideal

 

[MirrorProfiles]

I actually think it's a worthy trade off if the captures are significantly better. Not sure what it means by connected to Rig Manager though - is that only via USB or Wifi/ethernet/mobile too?

But also; release a plugin already.

Is it my turn to accuse someone of having shit ears and needing to visit a doctor???
