  • Network issues

    Hi

    I've just spent a very, very frustrating day battling all kinds of issues with my studio, some of which I believe are Cubase bugs, possibly some hardware issues, but a couple which I can't solve, that affect VEPro - I'm hoping some network experts have seen these issues before and can help.

    I have a system with a win7 DAW and two win7 slaves - all completely built from scratch, everything installed very carefully, and set up identically. Yet slave number 1 is behaving differently, on the network, from slave number 2. When exploring the network from the other machines it appears as both a PC and a media streaming device, even though media streaming is turned off on all three, Media Player has never been run, I don't have iTunes installed, nor anything else which might want to stream media, other than VEPro. I don't know whether it's a problem that it appears as both, but it does have issues with playback. When I use it as a slave there is a regular 'pulsing' (somewhere between a click and a pop, but constant at about 80bpm) in the audio that comes back. It's not related to the bpm of my Cubase project, nor the clock on my keyboard, nor anything else that transmits a MIDI beat - as far as I can tell. And I discovered today that it starts occurring when the machine appears in the 'Media Devices' list on the network. So long as it doesn't (and I still don't know what makes the difference) this pulsing doesn't happen.

    Secondly I have audio dropouts in the streamed audio from both slaves. This varies from being an extreme problem to non-existent, and I also can't find a reason for it. It's not that there are dropouts ON the slaves, but in the capacity of the network to return the audio. This can happen when I'm only loading one instrument, and playing one note on the slaves,with only a single stereo output on VEPro, so it's not a capacity thing. So far no amount of fiddling with network settings seems to make any difference at all. I've tried it with JumboPackets on and off, Green Networking on and off, every possible combination of enabling collision management, etc, but it just doesn't stop. It's usually worst when the network has just been turned on, but sometimes it doesn't happen at all, and sometimes persists so long that I give up on doing any work. Anyone else having similar issues?


  • I have the same problem here with a Mac installation...

    The last VEPro update made it a litle better but what seems to happen here is the CPU usage in VE Pro witch drops sundenly to 0% and that cut the sound ! then it comes back and forth...

    Very anoiying as my system worked fine untill a couples a weeks ago and I've been triying everithing I know to solve this (network installation, set up in Kontakt and VEPro etc...) but nothing worked so far...

    Maybe another update is on it's way ? if so let us know when it will be available and if you can replicate this strange behavior...

    My setup : Mac Pro Nehalem 2x2,26 Ghz Quad core Intel Xeon with 32 Go Ram, SSD drive for system and several HD on external FW 800 this is the Master DAW runing Nuendo 6.0.7  then i have and I-Mac 3,2 Ghz Intel Core I5 with 32 Go Ram with external HD for libraries. Both are running OSX 10.8.5 and are connected by Ethernet to a hub with cat 6 cables (all new)

    Regards


  • To complement the information about this issue I did download the last E-licencer update and also tried previous version of VEPro (5.3.13240 /5.1.11947) but it didn't solved the problem...maybe if you could provide me with a 5.2.xxx version I could try ?

    This setup used to work fine untill suddenly it didn't so I'm thinking if I could find the VEPro version that worked...

    Please get back to me on this asap so we can figure out the problem, as for now I can't use any slave !

    Regards

    Sadly no - they're all static.


  • Can you give the system pref/Network/TCPIP value of your machines ?

  • the same 6 digit for both machines xxx.xxx.0.5 for the master and xxx.xxx.0.1 for the slave

    sub network are identique on both machines

    routeur is the smae on both machines

    same DNS server on both

    IPV6 seems to be the same on both

    Does that help ???

    I Just wrote to VSL support as I really need this to be solved


  • try this tutorial :

    http://cyrilblanc.fr/site_principal/slave_mac.html

    and tell me if it is working

  • Hi Cyril,

    Thanks for the reply.

    It seems that your tuto is for connecting two Macs together witch wasn't really my issue but I gave it a try after exchanging with Marnix from VSL (it was about forcing connexion speed to 1000 base T on manual witch I did plus chaging MTU to jumbo (9000) but it didn't help the CPU usage on VEPro to drop to 0% and to cut the sound).

    So I connected my slave I-mac directly to the second ethrnet port of my Mac Pro and enter manually the new DHCP adress witch is a new one.

    At first it seems to work but then I tried with my orchetsral template and even if the issue apear less frequently it stills drop the CPU usage to 0% etc...strangely enough this doesn't happen when I export audio in non-realtime mode !

    so I guess we are in the right direction but still some way to go...I hope the VSL support can get back to me (they stoped suddenly to reply).

    Another thing that your setup disturbes me for is that I canot connect a third slave witch I do sometimes with my MacBook Pro for some big project...do you think I can turnaround that DHCP adress without using the twoo port of the Mac pro ?

    Thank you anyway this was interesting and going in the right direction ;-)

    Regards

  • I am happy to hear that you are progressing.

    doing this ; you create another network

    If you want to connect a 3rd Mac you need a switch

    You can run again my tutorial and see what adress you are getting

    Concerning click and pops :

    - See my configuration I have a SATA III card and raid of SSD for my libs

    - I had problem of preload buffer length on some instruments. You have to isolate the part and the track. For instance, I had to increase the preload buffer size of the trumpet B

  • I'm using an switch Trendnet 1000 base T, You mean that if I use my swith connected to the second port of the main mac pro I'll be able to connect several mac to it with the same procedure ? great news !

    as for the the HD I agree with you that the fastest the better but I have this drop out problem even with just one sound loaded !

    Also I used to work with this setup untill few weeks ago and it was working like a charm with my 300 midi-track template :-)

    I'll keep you posted if we find a slution to this issue.

    Thanks for your help.

    I have not try it

    > as for the the HD I agree with you that the fastest the better but I have this drop out problem even with just one sound loaded !

    look at what I said about pre-load buffer size in my previous post

  • How much did you increased your buffer size in Kontakt ?

    mine is around 90 Kb on the slave and 60Kb on the master


  • I was speaking of VSL preload buffer size(in Directory manager)

    I use Kontakt in the DAW not in VSL

  • Ok then I get it ;-)

    I checkde that, it was on default so I increased it but it just concern the VI Pro and my issue appear aswell with Kontakt 5 inside VEPro and Omnisphere etc... so I doubt this will solve the main issue but it might help the VSL library...


  • Hi again,

    After a short period of time of behaving better, thank to some help from Cyril, thing are again going wrong woth lots of cuts etc...

    Marnix tried to help me but apparently couldn't find a solution neither replicate the problem, so my question is : someone else having this kind of issue ?

    I really can't use VEPro in my set up so I can work with my large template !!! this is the reason I did buy this product...please I need a fix on this asap.

    Regards.


  • the worse you can do is to put your libs on FW

    If you want thing go better you must put your libs on SSD

  • Also having a FW audio with FW disk IS VERY BAD, you must check they are not on the SAME FW BUS.

  • I may be getting to the bottom of my problems at last. I think I had two completely separate issues, that just happened to have the same aural results. I went through all my machines, and turned off a bunch of background services - in particular Media Player Network Sharing service, and Acrobat Updater - then turned up my VEPro buffers to 3, and it seems to have dealt with all the dropouts from one machine.

    I think my other machine may have some capability issues, since I have a Samsung EVO drive for both the system and my Vienna samples. This one is still causing problems, but I'm hoping the promised firmware update for the EVO drives will help.

    If I was you I will keep system and Vienna samples of different ssd

    You can say why ?

    - System files are constantly evoluating/updated and there are the swap files that could make a lot of I/O so this disk will be morcelated !

    - VSL files are rarely updated, so your blocks will be continuated, allowing much more file I/O  

    The ideal would be to have a separate disk or volume for the swap files, but with MAC OS X 9.x or 10.x I have not found any utility allowing to move the swap files. In MAC OS ?.? there was the "Suisse knife" but it is not supported anymore

    The cost is small If you add another 64 GB or 128 GB for the system 

    Do you SATA II or SATA III interfaces ?
