  • Strange popping noise in Horn Legato patches

    last edited
    last edited

    Hi!

    I'm currently in the midst of building a new orchestral template; and when I started balancing the tracks, I noticed a strange loud "pop" sound in my Triple and Vienna Horn Legato patches. It's only audible in the standard legato patches (and during what I presume is transition samples), not the sus-Leg patch. And it seems that this bug (?) is only present in these two particular instruments; everything else seems fine.

    Here's a short example with me fiddeling playing the Vienna Horn patch, just to demonstrate:

    VSL_Vienna_Horn_Leg_bug

    The error seems to be random, so the pops change for every playback. Does anyone know why this might be and how to fix it?

    I'm using SE Plus vol 1-2 and vol 4
    Cubase 9 Pro
    VEP 6
    Win 10

    Any help greatly appreciated!

    EDIT: Upon further testing, I found that the same kind of pops also appears on the Legato Patch of "Trumpet ensemble (6)" instrument, when playing repetitive notes. This surely can't be right? Check below example:

    VSL_Vienna_Trumpet_ens(6)_Leg_bug


  • Hi
    You can also try with strings and other instruments and you will get those "poppings" again. Of course this is not a bug from VSL, but probably a weakness of your audio interface. Maybe it's a good one but you probably still demand too much from it anyway.
    So check out the buffer amount of it. Could be that you need to increase your buffer amout slightly. Instead of 32, 64 I would try with 128, 256 or 512... or even higher. Also try to either turn on or off the "audioguard-function". What often helps as well, is a higher setting for "prereading audio files" (instead of 2s set 3 or 4s)
    Sometimes these poppings only happen until every note has been played the first time... There are many possibilities - but it is definitely not a bug on the side of the samples.

    I wish you a lot of success

  • Thank you so much for your reply Beat! :)

    I have now played through ALL other instruments' legato patches, just to double check. And the results are in:

    Solo Viola + (popping only in higher key ranges, from around F3 and upwards)
    Clarinet ensemble + (popping)
    Bassoon ensemble + (popping)
    Horn Vienna + (a lot of popping)
    Horn Triple + (a lot of popping)

    These are the ONLY patches/instruments that have this problem. And only in the Legato articulation. All other instruments works like a charm. I have my buffer set to 512 (RME HDSPe RayDAT), and my ASIO meter is resting at around 30%. My whole template is around 1500 tracks, and everything else (even more demanding libraries and legato patches) works fine. My ASIO-guard in Cubase is Off (as also recommended elsewhere).

    By "prereading audio files" do you mean the "Disk Preload" setting in Cubase? I could try to raise that. But it would seem odd that it is only these 5 patches that generate this pop. And Disk Preload only has to do with playback, not live playing, no? 

    Do you have any other idea what it could be? Thank you again for your help!

  • Also; please note that the popping noise only happens when playing the standard Legato patch (pLeg) on the "Horn Vienna" instrument, not the Legato sustain patch (pLeS).
    Which seems very odd, considering they both play the same kind of "true legato" transition samples..so they should be equally taxing on the system(?). 
    That's what led me to believe that there could be something going on within the patch itself (or my VIP version or whatnot), and not a problem with my DAW...but what do I know? :)

  • Hi Daniel

    I'll be able to give you some more tips tomorrow, Saturday. At the moment I'm not at the computer and by heart I do not know all these technical things either.

    I also work with Cubase 9.5 and will check my setup (RME UFX +). Why not using the ASIO-Guard? I never had any problem.

    There are also settings in the Vienna Instrument that reduce such "failures". But, I have to be able to open such a VI as mentioned...

    Hi Beat!

    UPDATE: I finally fixed the problem by raising my Preload Size in the Directory Manager! So no more pops!
    I run everything from SSD😖, so I set the Preload to 2048 quite some time ago, and have had no problems up until now. So I didn't even think of checking that. I now changed the value to 8192 for the specific affected libraries, and it's all like clockwork (a few more Gb's of RAM usage, no biggie :)).
    I now understand what the problem was, but it seems weird to me that the "Voices" meter in VIP barely moved, it was hovering around 0-15 voices while playing, but I was still getting pops. So I it wasn't very obvious what the problem actually was.
    It was only when I, by chance, tried playing full chords with all Vienna Choir patches simultaneously that I heard pops again, and that little red dotted line (which there is no documentation on) under the Voices counter actually moved and sometimes maxed out. That gave me a hint of the issue. So, hours spent troubleshooting, but I guess I've learnt something in the process 😊 

    Thanks anyway! Really appreciate the input! 

    PS. Regarding the Asio-guard; I've read several sources claiming that the compatibility between VEP and Cubase is shaky (seconds delay when switching between tracks for example) when having the asio guard active. I'm yet to decide which way to go, but for now it's deactivated, and all seems to work ok. I'll do some more testing and see which works best 😊


  • I had exactly the same issue with the dimension brass 1. And solved it in the same way!

    I know this is old, but saved me hours! Thanks so much 😊

    I had these pops, but my Preload was set after running the Synchron player check tool. So I dropped these down and now zero issues.

    Just thought I would say thanks, and bump the fix for any recent buyers that may have a similar problem.
