  • VEP7 and Logic: cracks and pops

    Hi there, I tried everything, I don’t know what to do.
    I recently made a full orchestral template using Spitfire’s Abbey Road One and Cinematic Studio series. Nothing too big, just a couple libraries divided by articulations, 14 instances total.

    My host machine is MacBook Air m3 16Gb Ram, my Vienna machine is PC i5 128 Gb Ram

    Logic doesn’t do much, just Vienna plugins and a little built-in stuff I tried switching off to no effect.
    Both machines run way below peak for both CPU and RAM.
    My network is 1 gigabit both ways, a type C hub with RJ45 jack on MBA and a built-in Realtek network adapter on Windows, both systems show 1 gigabit network bandwidth, fixed IPs, the cable is 8-pin, network monitoring on both machines shows like 10-50mbps (actually, windows shows more traffic sent than OS shows received, for some reason)

    All libraries are on a 1TB m.2 nvme SSD inside the PC. Disk activity shows no peaking.


    Yet the audio clicks and pops like crazy at any buffer size, and those artefacts are especially bad in a printed (bounced) file. Like it crackles a little during playback and a lot during bounce.

    I tried changing the number of threads per instance, Logic’s buffer size, Logic’s processing threads, Logic’s process buffer range, disabling sample-accurate automation, everything I could find on the forum.

    What on earth is wrong with this thing? Please help. If there is any info about the system I missed, I’m ready to provide it.


  • Have you tried running VE Pro with the project with the 14 instances on you Macbook Air? 16 GB Ram might be sufficient to do that. It would trace if it is your connection between the PC and the Mac,

    I realize it might involve some work if you do not have the libraries on your Mac or on an external SSD but is maybe worthwhile. The fact that the PC is sending more info than the Mac receives does maybe mean a faulty connection.

    I assume you did try different cables to connect.


  • 1 instance use 2 processors by default. make the math f you use 14 instances . each instance will show you in % of easch instance cpu use . cinematic studios strings ia a memory ram killer. if you did divide css in articcualtions probably you got your ram overstretched.


  • Any solution to this? I have something similar... plenty of hardware capability and yet still getting distorted audio.


  • @simon5413 if your audio is distorted ,( if i understand you well ) it mean your input in cubase is to high . some people will simply reduce main volume of specific instrument in syncron player. to my opinion by doing this you going to disbalance the orchestral dynamics that are so helpful for your own work flow. if you control the input signal not by lowering down the output of main volume in sychron but the input in cubase and than through a bus output as track volume controle you will lose all the distortion . of course all inputs and buses have to be balanced the same you do with other tracks to avoid distortion in main output or buses in cubase .


  • I'm having the exact same issue with Mac Studio m2 and a slave PC 8 cores with win11

    No matter what the buffer size is it distorted in a digital way that is very weird.


  • @ilirjan -- this is not a case of too high volume. This is any sound at any volume and the distortion is almost 8-bit sounding.


  • Update: I have discovered that this issue appears to happen only when another app on my DAW (VE Pro 7 host) is opened AND has audio capability.

    For instance, while I have Logic Pro (11.1.1) open with an active connection to my VE Pro 7 slave, I can play any instrument freely without degradation of signal. But the moment I open up another app (such as Safari, or Ableton Live or Chrome), the sounds triggered on the VE Pro 7 host will in short order become digitally distorted and if I keep laying will eventually stop making sound all together. I don't even need to be playing audio through the other app, merely opening it is enough to trigger this.

    I will add that if I play audio through any of these apps I mentioned it sounds normal. The distortion only happens on the VE Pro signal chain.

    If I play any sound through an instrument loaded in Logic (locally) there is no issue.



    So clearly there is a conflict in resources at play that is causes VE Pro to get deprioritized in service of any other app that has audio capability.
