Kenneth,

Thank you so much for your detailed explanation concerning natural volume. I had some misconceptions about it, and I now have a better grasp about why it's there. I dug my piece where I experienced this issue concerning natural volume and realized it was not a timpani but rather a bass drum. Here are the two snippets (bass drum comes in at 20 seconds).

NATURAL VOLUME BASS DRUM

You will hear the -8db most likely sounds more natural than the Natural volume one. Please note, velocities are 100 for both.

Maybe this equation needs to be refined, because really, if someone doesn't know what natural volume is, the impression he or she will get is "Oh, let me click this to get a natural sound, natural balance).

Thanks again for your thorough explanation!

Cheers,

That impression would be correct, assuming "natural" means the resultant air-pressure waves would be objectively the same as the air-pressure waves generated by a live performance in the real physical world.

If you confuse -- as Kenneth does -- "natural" to mean "artistically preferable", of course there's no button that can read the minds of your listeners to find what they prefer to hear.

You're world of objective robots is not what you think it is.  The world is too complex for such a simplistic, reductionist view of things.  As much as you would like things to be reducible to your vision of machine perception it's just not so.

Recalling what I said in my closing paragraph, one of your robots would provide you with different data, different measurements, for the same instrument, in each and every virtual venue you place your sound in.  That's acoustics.  And that's the way acoustics impacts in a very objective way on perception.  The two cannot be detached, sorry 'bout that.  Science at is foundation is based on perception, observation, a training of the senses to the subtle differences that make for significance and meaning in the world.  Leonardo da Vinci worked that out for us 500 or so years ago. And every philosopher worthy of the title over the past several thousand years has struggled with the issue of what we know and how we know it.  Read Martin Heidegger on the origins of the work of art, also his thoughts on technology.  Art is a revealing of Truth, as is technology.  The Greeks knew that three thousand years ago.  That's why their word, techne, encompassed art, technology and knowledge.  

And really, must we descend into childish name-calling?  "Touchy feely" is simply meant as a denigrating statement of the considered language of someone trying to engage, meaningfully in a dialogue on an interesting topic.  I wasn't aware that you were the moderator of this thread.  You simply started it, and it goes where people would like it, reasonably, to go regardless of your wishes.  That's not hijacking, it's called conversation.  Again, sorry for the real world in all its complexity, this time social, impinging on your view.  I'll move on now.

I appreciate you now understand this.

Best,

Kenneth.

Playing the bass drum at a velocity of 100 is Forte, and you don't want forte in your example, 

try playing the Bass Drum at a velocity of 60, and leave everything at Natural Volume,

Perhaps you could approach this from a different angle,  leave Natural Volume as it comes, and adjust the dynamics of the instrument (velocity) to achieve the right balance, as that is how it would be in the real world. (assuming your have Vel XF controlled by velocity)

I understand that you don't understand what Natural Volume is, and you'd rather give speeches about Art than learn how to operate this computer program you bought.

Indeed, with 60 it's much much better. Thanks!

If you confuse -- as Kenneth does -- "natural" to mean "artistically preferable", of course there's no button that can read the minds of your listeners to find what they prefer to hear.

What natural volume is to me is this for example: I go to some hall and there is an ensemble there but there are no microphones whatsoever. The sound coming out of this ensemble is natural (irregardles if it's pleasant or not). Like this one: https://dl.dropboxusercontent.com/u/33556625/Music/Chamber%20Orchestra%203.m4a

Just my iPhone recording. There are no mics, just the natural sound of the instruments and hence volume. So I expect that is what natural volume tries to simulate.

BachRules, I tend to agree with Kenneth in many points. You can't ignore perception. One example that comes to mind is this: Have you ever watched the weather person say: It will be -5 degrees but feel like -17 with the wind. How do they measure the  "it will feel like" part if it can vary from person to person?

If you set your volume faders all to the the same level, turn on Natural Volume, and use only velocity (and instrument-positioning in the MIR room) to control loudness, your will get combinations of timbres limited to the combinations which are possible in the real world. This optional limitation is the purpose of Natural Volume. When you want real-world-possible timbre-combinations, allign your faders, turn on Natural Volume, adjust velocity (and instrument-positioning in the MIR room) to countrol loudness, and leave the faders alone.

When you reduce velocity on your drum to 60, you are taking advantage of Natural Volume. When you alternatively leave velocity at 100 but attenuate by 8 db, you're breaking the don't-touch-your-faders rule and you end up with a combination of timbres which isn't possible in the real world. In the real world, you can tell the drummer to hit the drum less hard. That's like reducing velocity to 60. In the real world, you can't tell the drummer to hit the drum 8 db quieter while maintaining a constant timbre. That's physically impossible in the natural world; that's what you get when you leave velocity at 100 but lower the fader 8db.

None of this is to say what your listeners want to hear, or how you should do things. Just describing the objective science of the Natural-Volume button.

Yeap, I get it now. I wasn't aware of this before. It's just that the loudest velocity sounds a bit too load in the case of the bass drum.

Thanks!

But this thread is about the number that shows up on the thermometer, and that number is unaffected by your perception of the temperature; and so, human perception remains totally irrelevant for the intents and purposes of this thread.

If you really, really are unable to ignore perception, you will believe that your perception of the temperature will alter the number that shows on your thermometer. That would be egomaniacal, to imagine your perception alters the functioning of thermometers. But hey, we live in a world where authorities imprisoned Galileo for claiming the earth isn't the center of the solar system, after all.

By bringing human perception into this discussion, the most you can achieve is continued misunderstanding of the Natural-Volume button on your software. Suit yourself. Natural Volume isn't about what you perceive. It's about the objective motion of your speakers and objective waves of pressure passing through the air. How your brain perceives those pressure-waves is none of Natural Volume's business.

Now I'll leave you and Kenneth to agree that human perception is relevant to the functioning of the Natural Volume button on your software. I concede the election: The MIR Natural-Volume button functions however you and Kenneth decide by consensus. The machine-code compiled inside MIR will alter itself to accomodate your perception.

I have no more time for this lunacy, as I'd have no more time for egomaniacs believing their perception of the temperature alters the numbers a thermometer displays.

I get you and know where you are coming from. The point I was making is that natural volume may need further refinement so that you are not left on having to use your perception and make adjustments.

Natural Volume simulates a natural orchestra. Composers for real orchestra have to decide which dynamics to assign each note (ppp, fff, or somewhere in between); and true to that model, Natural Volume leaves VSL-composers with the burden of deciding which velocity to assign each note.

There could be an added layer of technology which assigns dynamics (velocity) automatically, but VSL's Natural Volume was never intended to do that aspect of composition for you.

I'd buy software to compose my dynamics for me automatically, if I liked the results. But hopefully they'd name it Artistic Dynamics, so as not to confuse it with Natural Volume, which is a science, not an art.

I agree, and it would be ideal if natural volume is not just a guide. Personally, I would take it a step further when it comes to EQ as well, but that is for another thread.

No, that is not correct, because it ignores the differing dynamic range of instruments. There is probably one dynamic at which this is true, but as I have no idea as to how the Natural Volumes were calculated, I have no idea which dynamic it would be.

I have always assumed that it is based on the maximum level ot the loudest dynamic (maximum SPL of that instrument),  but the huge diversity of dynamic ranges per instrument makes things somewhat more complex, especially when a piece may not be utilising that dynamic range.

If I ever need to make large changes to what Natural Volume has set,  I can't help feeling that I must be doing something  a little unnatural.

You may well be correct, but the problem with that assumption is that an orchestra almost never plays at its loudest dynamic, so if it is true, then in real terms the Natural Volume will almost never be right.

I'm not understanding your point. Not disagreeing with you, but I don't understand what you mean.

To use Mural as an example, if I set my volume faders to the same level and use only velocity to control loudness, I get only the timbre-combinations which are possible in the real world. I get this despite the differing dynamic range of instruments. Or are you suggesting Mural doesn't work this way either?

Mural gives Natural timbral relationships, and only Natural timbral relationships, at all dynamic levels. Just like a natural orchestra -- the diversity of dynamic ranges works against this in no way. This is how I conceive of Natural Volume, though it's possible that I still don't understand how VSL Natural Volume works or what it does.
