    I'm trying to better understand the Pre-EQ function in MIRx. When I turn it on, it sounds good to me; but I'd like to know more. The MIRx manual states, p. 12:

    PRE-EQ

    We have matched the best positions for each instrument and section in every MIRx Venue with carefully tuned Equalizer Settings.

    > The Pre-Reverb Equalization adds to the virtual representation of your instrument and tames potentially problematic frequencies that result from the architecture of the selected hall.

    > Additionally, the Pre-EQ also plays quite a big role in character presets such as the Solo Strings Presets!

    > Try deactivating the Pre-EQ with a few presets, to hear the difference!

    > As an alternative, you can also use the built-in Pre-Reverberation Matrix Equalizer, available in the Matrix Tab of the Advanced View....

    ! VI Pro's Matrix EQ und der MIRx Pre-EQ verwenden 2 verschiedene Prozesse! MIRx's Pre-EQ entspricht MIR Pro's "Character EQ"; die individuellen Einstellungen sind nicht editierbar.

    I don't understand that last paragraph.

    If the instruments are recorded realistically, and the MIRx impulse-responses simulate the various venues realistically, is the Pre-EQ diminishing the realism? If there are "problematic frequencies that result from the architecture of the selected hall", wouldn't a real listener in the real hall hear these problematic frequencies? Not that I consider realism to be the paramount consideration in all my music, but I try to keep track of it.

    How were the Pre-EQ settings derived? Is there a science to it, or the preference of experts at VSL? Not that I could do as well if I went at it on my own; just trying to understand what this is doing.

    Hi,

    there was indeed an untranslated German paragraph in an older version of the MIRx Manual (... which is kind of a mystery to me, as we usually write the manuals in English first and translate them to German afterwards .... but I digress ... 8-) ...).

    This is the translation, as it can be found in the most recent version of the MIRx Manual on p. 12:

    VI Pro's Matrix EQ and the MIRx Pre-EQ are using 2 different processes! MIRx's Pre-EQ relates to MIR Pro's "Character EQ"; the individual settings cannot be edited.

     

    In other words: You can use VI Pro's built-in EQ in any case - it's not the same EQ as the one used for MIRx' PreEQ (a.k.a. "Character EQ" in MIR Pro .... for some reason the developers of VI Pro decided that the label "Character EQ" had too much ... uhhmm ... character? ... but I digress again.)

    The PreEQ itself will neither enhance or diminish realism. It's just meant as an easy way to achieve different, but meaningful colors for each Vienna Instrument, which ideally fit all other MIRx'ed instruments within the same Venue. It's like moving to the seat on the left in a concert hall, or in the row behind you - the perceived sound will still be "real", but quite different in any case. It's up to you to decide if you like it better than before. 😊

    All MIRx settings like Microphone Setup, Room EQs, positioning, stereo width, rotation, and PreEQs were derived completely unscientifically, using my ears, my taste, my time (!!!!), my monitor speakers (and some auxiliary technical devices) - based on Herb's suggestions and his feedback.

    ... I hope you like them nonetheless. ;-D

    Kind regards,

    I do like the results. Thanks for the explanation.
