Please report all settings

Hi Cyril,

I am having similar issues ( see post yesterday about new mac pro) . Can you clarify for me

DisbaleBluetooth : Does this make a diference ? ( I like to use the apple bluetooth mouse for horizontal scrolling 

- set his preload buffer to maximum

-- 

Is that in Vienna instruments ? What about Kontakt ?

 set its DAW with large buffers and it's I/O buffersize to maximum (1024)

For me  a 1024 buffer is too high latency wise 

Hi Charlie

You disable all non needed (Wifi, Bluetooth, Flash ......)

To see if you have enough CPU power and enough fast disk you should set all pre-load buffer size to maximum (in you DAW and in VSL)  

Is there are no more problems, you can start to reduce them until you get problems ! and set it back to the values where there is no problem.

Then if the latency is not acceptable, you should go with SSD and/or put memory to  32 or 48 GB, and/or change computer, and/or add slaves

For Kontakt it is the same, also it is better to have Kontakt in the DAW, if you put it in VEP you will add another layer in the processing.

Best

Cyril

Is there a performance issue that goes with this spike, or are you just troubled to see it?

If VSL engine loads in memory a small chunk of the sample he has to play (depending of the size of the preload buffer size) if it does not have time to read the rest of the sample in time, you get problems.

VSL engine, need fast CPU and fast disk access, all that depending of your template.

Thats why I bought the new mac pro 3.5ghz 6core with 64 gig of ram and 4 1gig ssds,

Should have just bought a cheap pc 

If you want I can test one of the piece where you have problems

My CPU is idle à 65 % on large and heavy score, and at 85 % on normal 

Can you give more detail on how you have organize your orchestral template.

That [Sam's] computer is very comparable to mine, and I get on pretty well. Without worrying about all of this theory, without SSD, without RAID. I actually do music all day with relatively few hiccups. I do not think the things Cyril is saying are it. For instance, the preload buffer for Vienna is by default high enough.

So, first things first: are you having trouble with performance or just trouble with something you see in activity monitor? I have seen things that don't even add up in it, for instance.

The symptoms of actual troubles will be more indicative of problems I think.

Not sure what settings I need to post. I've got 2 threads per instance. My buffer in Digital Performer is set to 256 which works fine for me.. 512 introduces a little too much latency for my tastes. But regardless, the CPU doesn't seem to be connected to buffer size at all. Like I said, it's totally random. Sometimes it's running at 9%, sometimes 90%. When it's that high, yes, I get lots of stuttering and skipping.

Can you give the figure in Activity monitor/memory after you had "stuttering and skipping."  

Put 8 core in VEPRO setting and Pre-load buffer to normal  in Directory Manager

Put DP with 1024 and test if it is playing ok, if not put pre-load buffer to bigger (you must re-launch VSL each time you change a parameter)

see : You disable all non needed (Wifi, Bluetooth, Flash ......)

Reboot, do not lauch any softare, only VSL and DAW

Buffer settings make no difference.. again, sometimes VE Pro works fine, sometimes not. Directory Manager doesn't matter, since I'm not using any Vienna instruments. Kontakt only.

It just spiked a while ago at around 60-70%. In Activity Monitor it said 450% CPU usage! The only thing that fixes it is restarting VE Pro and reloading my template. Now it's idling at around 25%. Activity Monitor reports around 170% CPU usage.

higher than 100% for an application just means that more than one core is being used.

MY experience is that Kontakt|VE Pro is VASTLY more efficient than Kontakt as a plugin in Cubase. Because the plugin is not waiting in line for CPU, for one thing.

Uh, yeah.. it's quite odd to say that Kontakt does not work as well in VE Pro as it does within the sequencer.

I think I'll contact official tech support. :)

What is the value of the "Swap used" ?

What are the value of the settings of K5 ?
