@synthetic said:
The advantage is that when you play a chordal pad on clarinets, french horns and cellos, the clarinets don't overwhelm the other sections in volume because that wouldn't happen in a real setting. Since sample libraries are always optimized to max volume, it's up to us to balance them to each other. A chart that said that clarinets at forte are 12dB quieter than horns at forte, for example, would allow the composer to set their clarinets to -18dB on the channel meter (allowing headroom) and horns at -6dB. When they play together, the balance should be close. For those of us who don't spend as much time with real orchestras, a balance guide would be useful.
Something like that?
Valve Horn 1th to 6th1st Horn distance to mic 9,0 meter
Direction -5°
Dynamics: ppp = -43.0 dB rms, fff = -16.5 dB rms
6th Horn distance to mic 9,5 meter
Direction +12°
Dynamics: ppp = -42.0 dB rms, fff = -16.9 dB rms
Clarinet 1th to 4thDistance 1st Clarinet to the mic 6,5 meter
Direction 1st to 4th clarinet -5° to +9°
Dynamics: ppp = -48.0 dB rms, fff = -17.1 dB rms
Celli 9:Distance to microphone 2,5 meter to 6.5 meter
Direction 50° to 65°
Dynamics: ppp = -52.0 dB rms, fff = -17.5 dB rms

But what would be the parameterization for the measurement in order to make the chart?
1) A symphony orchestra in a recording situation, who becomes your template?
2 At which point would you measure this "relative loudness? Would the measurement be made with one stereo microphone only, or a decca tree?
4) How wide is the stereo basis of the to be measured orchestra, or will you stay withhin the stereo basis the VSL samples have? What is the stereo basis of the VSL samples?
5) What do you want to achiev in your mix? Is the goal to copy a recording of a real orchestra, or do we want to invent our own virtual music?

Even if VSL would give us this loudness information, as they are in the silent stage, the dB SPL's wouldn't be of much use to the composer and mixer; because the seating plan of a real orchestra is already a balancing; where the silent stage does not copy this situation, but rather records all instruments from an uniform distance we don't know.
To me, working with VSL is like mixing a multitracking session with spot mics at every single instrument and group, then it is decided in the mix how loud an instrument is overall in the mix.
I remember when the Berliner Phil's where recorded for the first time with a digital 32-tracks machine. The engineer had tremendous problems to balance the multitracks, compared to what a single stereo microphone balances almost automatically.
