Solved Kontakt changes Frequency Response of used Samples

When I record Samples and listen to them they have a specific Frequency Response. When I load those Samples into a new and blank Kontakt Instrument then Kontakt removes a bit from the Low Frequencies and add a bit to the High Frequencies even if there is no EQ Effect added. Why is that and how can I avoid this Behaviour ?

 

Kontakt doesn't do any such thing. But Kontakt's default instrument has velocity modulating amplitude already set up, and also group volume is set to -6 dB and instrument volume is set -6 dB, so your sample already doesn't play at the volume you recorded it at, which tricks your ears.

Also, if you play your sample lower than the root note, it will sound like a slight lowpass filter because that's simply the interpolation algorithm doing its job.

 

Thank you EvilDragon. I was thinking the same that it would be a shame if Kontakt would do such a thing. But if I listen to the Sample and then to the Kontakt Instrument it has definitly a lag of low Frequencies and a boost in High Frequencies. I know there are physical Influences in human ears if Volume drops or raises but that wouldn't explain why Bass Cuts and Highs Boost on a -6db Gain difference. I will try to adjust the Group and Instrument Volumes and compare again.

Interesting mention about the interpolation algorithm. But when I put the sample just on one key it uses this key as the root so there should be no interpolation, right ?!

 

Yeah if you play it at root pitch there's no interpolation.

Also, check if you may have some FX loaded in Output section of Kontakt. Although none should be there, by default. Also try different audio systems in Kontakt standalone (not sure if you're Win or Mac).

What I know, though, is that if I put a sample on a track in my DAW, then load that same sample in Kontakt, make sure group volume is 0 dB, instrument volume is 0 dB, Kontakt master volume is 0 dB, and that there's no volume modulation, I play it at root key and I invert phase on one of those two tracks, I get silence.

Sure it would explain it. Google Fletcher-Munson curves.

 

I love this one: "What I know, though, is that if I put a sample on a track in my DAW, then load that same sample in Kontakt, make sure group volume is 0 dB, instrument volume is 0 dB, Kontakt master volume is 0 dB, and that there's no volume modulation, I play it at root key and I invert phase on one of those two tracks, I get silence."

That would mean it's perfect equal wihtout any sound discolouration.

You are absolutely right. I raised the Instrument Volume by 12 db from -6db - could not find the Group Volume - and now the Instrument sounds identically compared to the recorded Sample. Thats amazing how the ear / brain fake the Sound Experience.

Thank you a lot!

 

Group volume is in the Amplifier section when you enter instrument edit mode.

 

I am replying to this thread because of a Similar problem. I recently purchased an 8Dio kontakt product, "Hybrid Tools Dark Prophecy" The sounds I am getting are significantly different from those I hear on at least 3 YouTube demos/walkthoughs. While I am sure there might be minor differences in sonic quality, it seems unmistakable to me that when I play the same instrumentssame notes, there is, at the very least, a significant rolloff at around 5K and possibly a low frequency bump. To pre-answer the "output effect' question, I am simply loading the 8Dio instrument into an empty Kontakt6 rack. I am concerned about this because all of the instruments in this library sound muddier and less defined than anything I heard on the web demos. If it were a single "A B" i would just suspect the Youtube quality. But the differences are pervasive and always in the same direction: absence of highs, possible LF bump. I am attaching some frequency plots ("A"=web, "B" = me) to show what is happening. I think if it were my audio interface I would not be able to record the web-demos without similar rolloff...so...any advice wold be helpful. If this thread is closed I will post elsewhere.

 

Youtube vidoes are postprocessed and compressed. It's an apples to oranges comparison.

Also, are velocity layers/round robins in play? This can also play a role in things. If stuff is modulated with velocity you'd need to replicate the exact thing played in the video down to velocity amount.

Also, did you make sure any sound enhancements are disabled in the Sound control panel?
