Altiverb 7 - One instance per instrument position?

Does anyone could tell me if - as already occurs in Altiverb 6 - I still need an instance of Altiverb 7 for each instrument position in an orchestra?
For example, for strings, one instance; for brass, another instance and so on?
This consumes a lot of computer resources.
Or is it possible to have all positions being managed by a single Altiverb 7 instance?

I like the second method described above. The first is more complicated, especially in orchestral music, as you have to adjust each instruments settings. It gives you greater control, but you really have to know what you're doing. The second method is much simpler and still saves on CPU.

Altiverb is a "true" stereo convolution reverb, meaning that it processes left and right channels independently. The first violin section, for example, will be mostly handled by the left reverb channel, while cellos are mostly handled by the right channel.
 
The purpose of this design is to mimic each instrument's position in the panorama within the reverb signal, in a manner similar to what a real physical space does. In a real room, the earliest, loudest and brightest reflections emanate from the same side of the room as the instrument.
 
That doesn't mean that the violins stay entirely on the left, though, because in a real room they also reflect off the right-hand wall and hit the listener's ear from that direction. Those reflections take a little longer to get to your ear due to the longer distance traveled, are quieter and have less high-frequency content in them. 
 
Reverb, whether natural or electronic, necessarily blurs the panorama. That's not a bad thing, especially when it comes to acoustical instruments and the classical orchestra. It's what anyone who's attended an actual concert would expect.
 
Which is a long-winded way of saying you'll be OK using a single instance of Altiverb on a reverb bus without compromising the placement of orchestral instruments. They should still sound natural.
 
Of course, sometimes "natural" isn't what you're after. You might want a left-panned instrument's reverb to be unnaturally stronger on the right, for instance, for a ping-pong effect. In that case, you might want a separate reverb just for that instrument, but even then I'd try using the send pan control first.
 

Each instance of Altiverb on the bus would replicate the
relative location of the particular "Section" that you
are adding Reverb to in the sound field.  You wouldn't have
two positions, but rather only one position in the "Stereo Field" and
Altiverb replicates that particular Position's acoustics in Stereo... 

It is indeed possible to have just have one Altiverb instance for all the instruments (or sections). You use the 'sends' on the console control panels. To have it on each instrument, you need to use multiple outputs on your synth. Sonar has some excellent tutorials on this. This allows you to adjust each instrument or group, with only one reverb instance. The difference comes from the sends, which you adjust for each inst. or group. Or you can go with the simpler method of just outputting the synth directly to the reverb instance. This does not involve using sends, and you have less control, unless you have more than one reverb instance. but it seems you want to avoid that. Thus, sends would be the way to go. I'm currently using two Spaces instances for an orchestral work, both with the same Hall, but one with  a bit more wet signal, which I adjusted directly on the Spaces instance. I change the output of the synths to the reverb I want, dry instruments getting the wetter one.

After all, it is what I am saying from the beginning: for each position, I need a new instance.
That was my question.
But thanks for all the support.

And that was my answer...i.e.

you would have one instance of Altiverb for the Strings
(obviously could even break that down to Violins, Violas, Cellos..etc..)
one for the Brass, one of the woodwinds, one for perscussion, etc..

You're "OP" said each INSTRUMENT position, not each "Section"...
while you could do each "Instrument Position" you are now using more
and more instances of Altiverb, which will continually eat away at your CPU...
 
 

Maybe you should look into Virtual Sound Stage? I've often been tempted to try it (which you can do for free). It is not a reverb,, but a spatial positioning plug-in, which lets you put each instrument exactly where you want it, in two dimensions. I hear nothing but good things about it, so it may be worth looking into.

Have you tried the suggestion of changing the pan knob on the console panel? 

I finally decided to ask directly to  Audio Ease support.
I think with this we have the entire solution at once.
Thank you all for the attention.

Hi Rogerio,
If you want to use multiple positions you will have to do this with multiple Altiverb instances.
But there is a trick:
the IR is divided in three parts, direct, early reflections and tail
the stage positioning tool controls the first two (direct and early), these are relatively short.
so, what you can do is create 7 AUX tracks.
insert an Altiverb on each, and load the same IR.
Then on the first 6 you turn off the tail (saves processing)
and you route the first 6 into AUX 7 and on this one you only turn ON tail (turn OFF direct and early).
Then you can set up 6 different locations on the first 6 aux channels.
Then route your instruments to these six locations.
Here’s an instruction on how to do this in Altiverb 6:
http://www.audioease.com/Pages/Altiverb/AltiverbStagepositions.html
in Altiverb 7 this works the same, then direct/early/tail controls are in the panel below the pre-delay and attack controls.

I hope this solves the problem! Sounds rather complicated, but these things usually are.
