Hi I'm recording with USB out of the Kronos in the SEQ (48khz). At 96khz the track sounds the most boomy. Can someone explain the effect of over sampling to 192 as far as the general sound texture and effect on mid range harmonics like in the hundreds. Not like technical stuff but the way this would affect a drum track / acoustics? I am wondering if anyone knows of a specific sound that it would carry at 48 to 96 versus 48 to 192 etc. thanks.

Supposedly, only your dog's ears might perceive some difference at 96K. I know you don't want to hear the technical stuff, but this is a good article at karma-lab:
Choosing a Sampling Frequency
(If you don't want to read it, it basically says to record at 48K, 24bit.)
If you are hearing something, maybe someone else could chime in about the USB settings. I haven't used them, yet. |

I always record at 44.1KHz/24 bit. There are a few VST instruments that have a lot going on in the upper end and some ampsims as well, but they all have a "HQ" button somewhere that effectively upsamples to 88.2KHz and back. I've never noticed any difference in regular recording quality. I think clock stability is a greater issue than sampling frequency. With a really good clock, there isn't really anything in the audible spectrum that you can't capture at 44.1KHz. And with a bad clock, even high sampling frequencies will be inaccurate. |

Oversampling when recording isn't that important, unless you're sampling rich harmonic content, or very high-freq content like cymbals.
It is more important when calculating non-linear stuff, like FM, ring modulation, distortion, waveshaping, because it pushes the Nyquist limit higher, which reduces overall aliasing in the resulting signal. |

Not sure what you mean by oversampling in this context? Because all DACs do this. |

I'm not talking about DACs or ADCs, I'm talking about oversampling in synthesis as a measure to combat aliasing. |

I just didn't get the "oversampling when recording". But I agree about softsynths! |
