How big is your project that takes 10 minutes to be able to play with?

It does not depend on the size of the project. Even if I open only one instance of Vienna Instruments Pro, I get random spikes for 5-10 minutes. After 5-10minutes spikes disappear. Only happens with Vienna Instruments Pro, not any other VSTi, (PLAY, Omnisphere, Kontakt).

Although I am very excited with the VI Pro2 (Amazing job Vienna! ), I have to say that the problem with the clicks/Asio spikes for the first 5-10 minutes when loading a Vienna Instrument Pro still exists.

Again, what happens is, when I load VI Pro for the first time I get random clicks/Asio spikes within the 5-10 minutes after loading it.

No CPU spikes, no DCP latency spikes. Only happens with Vienna Instruments Pro. I have a huge array of VSTi's (among them PLAY which is not renowned for its stability) and I don't get this behavior with any of them . Again it is not performance related. Fortunately, when the 5-10 minutes have passed I no longer get the spikes. I would really appreciate if anyone else who has the same problem chimed in or if anyone has a suggestion.

Thank you

Anyone else having pops and clicks when first loading a Vienna Instruments Pro?

Could it simply be that you are trying to play back things while the background loading is happening?

Playing while this very intense disk loading process is ongoing, will of course limit your performance.

Due to the fact that PLAY used to produce loud burst noises in the past if you tried to play while loading, I have learned to wait for samples to load before playing. But I think you've got a point, there's GOT to be some background activity going on when this is happening because after a while it disappears and I can playback a 30instrument arrangement without a single click or pop and with very low CPU consumption.

Just have a look in the VIPro gui. If the loading progress bar is visible - then you have ongoing background loading.

Thanks,

No, I always wait for the loading to complete. I was not talking of such an obvious background procedure. Vienna Instruments Pro is so quick in loading times anyway. There must be something else.

And my system is in the signature by the way, I run VI Pro2 in 64bit Cubase.

 I am working on a project right now. Just with one VI Pro2 Patch I get random spikes.

What I noticed just now, is that the spikes occur even when I am not playing anything on my keyboard. Turning off VI Pro makes the spikes disappear.

 For what it's worth,

I tried running Vienna Instruments Pro 2 in standalone mode. This yielded the same results. That means that this is not something relevant to my sequencer (Cubase 6) as it also happens when in standalone.

I am really running out of ideas, but I will let you know of further observations in case someone comes up with something. Just want to say once more that this ONLY happens with Vienna Instruments, all my other libraries (Kontakt, PLAY etc do not introduce this problem.

 So, I am demoing VEP5 now and the spiked are still present even with this configuration. I hope someone can give a hint on what may be the problem

Are you using the latest version of VIPro (9753)?

 I am actually running 2.09650. Thanks for the heads up. Is there something in the new update that might solve this problem?

Please install the latest version 2.0.9753. We have had some reports of issues with previous 2.0.XXXX versions.

 Thank you,

I installed the latest version (64bit) but I am afraid it has not solved the problem for me. Sound cuts off when loading a Vienna Instruments Pro 2 either VST or Standalone.

Can you give me your complete system specifications, any Windows tweaks and so on?

Of course:

Windows 7 64 bit

Dedicated DAW PC, no antivirus installed

Cubase 6.05 64bit

Motherboard: Asus P6T

RAM: 12GB DDR3

CPU: i7930

Hard drives: 500GB 7200rpm system hard drive, 3x1.5 TB 7200rpm hard drives. Vienna Sample Library is installed in one of the 1.5 TB hard drives with 64MB cache.

Video Card: Asus 9400 GT Silent

Audio interface: RME UFX, latest software (but same problem used to happen with RME Multiface and TC Electronic Impact Twin).

I have to mention, that I used to have the same problem on a Toshiba Windows laptop running Windows XP in the past.

It is very peculiar because, after 2-10 minutes pass, everything runs smoothly. Apart from that, if I close Cubase , restart it and use VIP again, the spikes do not appear. Same when I run in standalone. If I run VIP , close it, open it again, the spikes do not appear. It's just the very first time that I load an instance that these problems happen. And it happens even with one single instance, there is no difference if I add 1 instance or 100. Even if I have 50 VIP in some projects (sometimes I do), after 2-10 minutes everything runs smoothly.

Another thing to note is that when the spikes happen, Windows Task manager shows nothing wrong, and DPC latency checker reports perfectly normal values like nothing happened.

Hope that helps, if you need more info, I will be glad to provide you with it.

I have one more stupid question to ask. I did have another, but then you said that it happened with the standalone, as well as in Cubase, so it's now moot. Anyway, to my question:

What happens if you disable your Ethernet in Device Manager? Do you still get the spikes?

DG

Hmmm... Yes it definitely happens in Standalone. I also thought Cubase had something to do with it but I ran it Standalone and in VEP 5 standalone and still the spikes occured.

I will try to disable the ethernet controller but I am almost sure that this did happen in the past when I had the ethernet controller always disabled. Same thing on my laptop. Always had ethernet controller disabled and it still happened.

Plus, DPC latency checker shows very stable and low values around 100μs

But I'll give it a try. Thank you. Any other suggestion that pops in mind I will be happy to try as this may seem like a not so important matter but it gives me a hard time because I give presentations/tutorials with VIP and spikes are never good for people to see/hear.

The only reason that I mention Ethernet is that Windows searches for Networks and if none are connected it can cause pops.
