  • Channel Solo in VEP 7 Fails to Mute MIR Pro Split Wet Sends

    last edited

    Page 47 of the Vienna MIR Pro User Manual V.1.2 describes "Separating MIR's Dry and Wet Signals" -- a very useful technique.  For example, in my case I have a full orchestra mock-up in VEP Server 7 with 58 channels using MIR Pro, and per the above, I've routed the wet portion of each instrument's MIR wet signal to a single "MIR Wet Bus".  Unfortunately, if I then try to solo one channel (e.g., French Horn I), only the DRY signal gets soloed.  All 57 other instruments continue to play in the MIR Wet Bus, totally defeating the purpose of soloing.

    The only workaround is to solo the instrument AND mute the MIR Wet Bus. But then you hear the instrument dry only.

    This has got to be a bug (or design oversight) because it fails the "most obvious behavior" rule of software. But perhaps nobody has been clamoring about it because if you choose NOT to split wet and dry in each channel, but use INLINE on all channels, solo works as expected. 

    In my case, I don't want to use INLINE because the channel fader (in VEP or downstream in my DAW) is then also controlling my reverb tails, which is unnatural and unwanted. 

    Others are posting their Xmax wish list in one thread. Mine is that solo in VEP actually solos both wet and dry feeds from MIR Pro in a channel.  I'm begging you! 😊


  • Hi Stephen,

    you're absolutely right, this behaviour isn't useful for real audio work. I complained several times about the "Solo"-logic in VEP myself, but (to make a long story short) I've been told that this how it had to be done - considering that fact that MIR is some kind of hybrid engine that's not actually part of VE Pro, although the two of them "talk" to each other. - I really wish that I could give you better news. :-/

    Anyway: If you find the time, please write a few lines to support@vsl.co.at with an "official" feature request. It's always good to raise one's voice, in cases like this! :-)

    Thanks in advance,

  • what happens if you use the solo button that is inside MirPro (on the left side where you see a list of all instruments on the stage).  Actually now that I think about it, that is only in the AU/VST version of MirPro, its not there in the VePro built in version.  But there is a solo button over on the right in the Instrument section, but that appears to be linked to VePro's mixer solo button in some way.

    So one option would be to try using the AU/VST version of MirPro instead of the built in one.  I am not a computer to try it right now.

    To me that seems like the only way to solo an instrument and have both the dry and wet signals solo'd.  Otherwise, you would have to at the very least solo two channels in the DAW or VePro where the dry and wet signals are being sent from MirPro to two different channels.  The way you have it setup with all wet going to a mixed buss, you obviously can't solo the wet part of a single instrument that way, in the mixer.  But I guess you could solo it on the MirPro instrument list, yes?  I think in order to be able to solo instruments including both their dry and wet components when they are being split like that, I guess you'd need to create a seperate bus for each instrument.  Then you could solo both the instrument channel and the wet output bus for that channel together.  A mute group feature would be nice in that case.


  • My usual work-around is to solo the MIDI-track, not the tracks in VEP.

    ... but then, I only rarely see the need to split the wet from the dry signals anyway. :-)

    Kind regards,
