What exactly does Definition (really) do?

  • One way to check is to record a DI track. Send that track back for reamping. Take a profile, and record a track with the definition as stored. Record another track with the definition around 3-4 or so. Record another couple of tracks at 7 and 10.


    Do a tone match EQ to see what's happening with the EQ compared to the original track.

  • 'Overtones can be any frequency, so long as its above the fundamental. So, a harmonic is an overtone, but an overtone doesn't have to be a harmonic.'


    This is not correct: there is a specific order in the overtone series.
    Each instrument can have some of those overtones louder than others, which is the reason why the tone of different instruments playing the same note vary,
    but overtones are all positionned at very specific locations:
    Note -> 1st overtone up an octave-> 2nd overtone up a fifth from 1st- > 3rd overtone up a fourth from 2nd-> 4th overtone up a major third from 3rd ...etc
    Harmonics are overtones.

  • Harmonics are set frequencies above the fundamental. Overtones are not.


    It's in their definitions. Harmonics have set frequencies. Overtones are *any* frequency above the fundamental.


    The correct therm is harmonic sequence (or series), although overtone sequence (or series) is often used interchangeably. Regardless, the two words describe similar - but decidedly different - things.

    Completely disagree.
    The first search that you'll do on the overtone series will clearly show that the overtone series is set at mesurable, set nodes.
    You're wrong, sorry.
    Unless, by that, you mean that one is free to choose which fundamental to start with, which will determine at what pitch each of the overtones will resonate.
    But that is also the case with harmonics, so i don't see the point.

  • Nothing fuzzy at all. It’s math.


    Either we’re misunderstanding each other, and we’re saying the same thing, or one of us is wrong.


    I don’t much care which (or who).


    If I’m the one that’s wrong, fine. But I do not see that right now….


    “Overtone” is a term generally applied to any higher-frequency standing wave, whereas the term harmonic is reserved for those cases in which the frequencies of the overtones are integral multiples of the frequency of the fundamental.”

    “If the overtone is a simple integer multiple of the fundamental then it is harmonic, otherwise it is inharmonic.”

    Therefore, harmonic refers to specific nodes.


    An overtone may - but does not have to as it refers generally to any frequency above the fundamental.

  • Yes. See the last quote where it uses that term.


    An inharmonic would be an overtone. Just not a harmonic overtone.

  • I guess we will agree to disagree.
    Again, my issue is with this statement: "Overtones are *any* frequency above the fundamental"
    Overtones are not "any" frequencies.
    They sit sit at very clearly defined intervals from the fundamental.
    Whether you want to identify them as inharmonic is up to you.

    Fine by me.


    How you ignore multiple sources saying "Overtone” is a term generally applied to any higher-frequency standing wave..." or equivalent statements, I don't know.


    If I'm wrong I'm wrong, but offering no counter argument beyond "Your wrong, sorry" isn't persuasive.

  • From manual: Vintage amps distort the lower harmonics in the guitar signal which gives them their bluesy sound. Modern tube amps use a different approach, in which the higher overtones of the guitar strings are the driving force for the distorted sound.

    This is some great discussion. Now you see why I was confused about the above quote in the manual. This is from the section explaining Definition but doesn't explain what it does. and as we have witnessed in this thread, "overtones" and "harmonics" have different perceptions, but what did Kemper mean when the manual was written? Where does it say what it really does turning it up or down? Is it adjusting distortion in harmonics, overtones both or neither? I know If I wrote a manual I would just simply explain what definition does, You could likely do that in a paragraph or less.

  • Which is something I said.


    Overtones don’t have to be harmonics….its physics.

    I quote your link:
    "The term overtone is used to refer to any resonant frequency above the fundamental"
    The fact that it states that an overtone can be any RESONANT frequency doesn't mean that it can be ANY frequency.
    An overtone can be any of the upper partials above the fundamental and they all have a very specific spot in the frequency range, based on the fundamental.

  • Question: How do you label frequencies in the broadband signal that is NOT at a defined interval from the fundamental?

    This would imply the addition of a new frequency, independently from the initial fundamental frequency, not a resonant frequency generated by the initial fundamental.

    "The term overtone is used to refer to any resonant frequency above the fundamental"

    You are correct - perhaps I took that detail for granted or implicit and glossed over it. My mistake.


    At the same time - resonant frequency does not necessarily refer to a harmonic. Those have specific nodes, whereas other resonant frequencies do not. Hence the term enharmonic.
