Hi,
With MIR, one should choose the instrument profile matching the instrument to which the icon corresponds.
With Dimension Strings, it is common to mix and match players to for an ensemble. So, you might have an ensemble made of P1 and P3 (1st desk), P5 and P7 (2nd desk), P4 and P8 (3rd desk), and so on.
When in MIRx mode, it is very handy to use the preset placement of each icon. So, it would be quick to apply the instrument profiles in subsequent order. So, in the example above players and profiles would be matched this way:
(P1-profil P1) (P3-profil P2) (P5-profil P3) (P7-profil P4) (P4-profil P5) (P8-profil P6)
The alternative would be to match each player with the corresponding profile, and adjust everything by hand.
Now, this is the result of the two alternatives. Do you think they sound different? I'm sure I hear some slight difference in the end of the reverb tail, and maybe some diffent clarity, but I'm sure it is psychoacustics in action.
What do you think?
