    Hi! I am new to VE Pro 5. I am using Cubase 8 Pro.

    So when I use Ve pro from local master machine I get perferct performance with 512 samples buffer. But when I try to play any kontakt instruments from the Slave machine I get short dropouts every 2 seconds or so. I tried increaseing the buffer in the VE pro to 4 buffers and drop outs become less noticable but then the latency is just annoyingly big. I am using an amd 8-core processor and 32 GB memory on my slave and same thing but 64GB memory on my master. 

    I tried playing around with number of cores active per instance and turning on and off the multicore support in Kontakt. Also I turned off the Asio Guard in Cubase. Nothing helps. I know my Slave machine is capable of delivering good performance, I am just stuck at figuring out this drop out problem.

    Is there any trick that I just can't see to get the slave upto speed with the performance?

    Any help or any comment will be highly appreciated.

     

    Cheers,

    Tim

    UPDATE: 
    I just tested my second slave (Mac Mini late 2012 model with i7 3.2) and there were no drop outs even with 0 buffer and 128 samples latency on my sound interface. 

    Does that mean that there is something I have to do with my PC Slave? Any tricks on getting it to work stable with VE Pro 5?

    Hi, 

    Did you maybe connect your first slave over WIFI?

    What are your network settings? You should use static IP addresses, and avoid 169.x.x.x addresses (these are automatically assigned by your computer and tend to change).

    Please try the following:
    Manually assign one of these IP addresses to the computers in your setup: 192.168.0.x or 10.0.0.x, and assign a subnet mask of 255.255.255.0 (leave the other fields blank), then it should work. 

    Best,

    Paul,

    Thank you for the reply.

    No I connect them via gigabit ethernet connection. Yes the slave has a static ip 192.168.0.12 with default getaway to 192.168.0.1 and submask 255.255.255.0

    I have been running latencymon software on my PC Slave and it detects that I might have latency problems and dropouts because of "kernel memory latency". Is this anyhow connected to my problem? I thought that VE Pro 5 is just sending the proccesed sounds thru LAN network to master.

    Could it possibly be the ethernet cable? (I am using CAT5e one)

    Hi Tim, 

    It could be the cable (very rare, but worth a check). 

    What happens if you enter no value in the default gateway?

    I just changed cables to cat7 ethernet. Still same problem

    UPDATE: yes I was previously connecting to the Slave thru WIFI so I took out the USB wifi network stick, but now I cant even connect to the slave even by manually putting in the IP in Cubase 8.

    I tried leaving the default getaway blank and it doesn't change anything.

    Here are my Configurations:

    MASTER: (PC)

    ip 192.168.2.5

    255.255.255.0

    default getaway 192.168.2.1

    dns server 192.168.2.1

    SLAVE: (PC)

    ip 192.168.2.12

    255.255.255.0

    default getaway 192.168.2.1

    dns server 192.168.2.1

    I pinged to check the connection between two computers and it shows that its all fine. Also in advance network adapter settings I set the speed duplex to auto negotion, green ethernet disabled. Firewalls are turned off, network discovery is on, file sharing is on. I don't understand what else can I try doing to get this thing going. I need it working by Monday please if there is anything I am missing, let me know! Thank you!

    Hi Tim, I'd deactivate default Gateway and DNS Server. Any change? Best, Paul

    Hi Paul,

    Yes I deactivated them. Got connected by manually inputting the ip address. 

    Also reinstalled the Ve Pro 5 on both machines and it looks like the problem is almost fixed. Now just have to figure out the latency and crackling

    Thank you for the help so far, I really appreciate it!
