HELP : Conflict between Vienna Ensemble 2, Kontakt2 standalone on a Motu PCI system

[Cyril Blanc]

Hello

I am having a big problem :

I load K2 standalone, I load my default K2's setup no problem K2 is playing ok to out 25,26,27,28 of my Motu system (24i+2408mkII+1296+2408mk3)
I load the VE 2, K2 wont play anymore to the Motu's output (it is playing ok on the building line output)

Offloading VE 2 this does not solve the problem

To have K2 been able to play again I have to restart my MACPRO 8 core 3 ghz 13GB

Thanks in advance for your help

 Hi,

I have tried EXACTLY what you are doing, on a Mac Pro, with Kontakt 2, using MOTU 2408's. Similar problems.

My feeling is that Kontakt does not like to share a sound driver/device with other software. If have also experienced problems running Kontakt 2 (Standalone) alongside Steinbergs The Grand 2 standalone. 

Luckily, I had a spare 828, which I plugged in a ran Kontakt from. As it's a different device, Kontakt behaves normally.

As a workaround, once you have both VE and Kontakt up together, sharing the 424 system, if you just open and close Audio/MIDI setup in Kontakt, things seem to work. 

It's not VE's fault as far as I can tell.

Hi I have no problem to share the same device between Logic and K2 ;)
Looks like that VE is monopolizing the Motu.

And what is strange too is that even if you offload VE it does not give back the Motu to K2, I have to reboot !
Looks it's a VSL problem !
I Will post the question on the core audio developer list to find out who is culprit :)

Hi Ben

Speaking to Paul at VSL, he told me he has been testing that on a G5 with 10.4 and he has no problem
So it looks like it is either a 10.5 and/or a Macpro issue

Are you in the states ?

Hi Ben
I did more testing yesterday, the culprit is VSL Ensemble when you run it in standalone, no problem is VE is called via Logic

I have post a bug report and the answer of Paul from VSL is :

Hello Cyril,

I have to admit, that although this sees to be a big issue for you, it´s NOT on top of our priorities. We will look into it if we find the time.

Best regards,

I hope it will not take too much time 😉 VSL reputation is there 😉

 For my  money, I am sory to have to tell you, it's a Kontakt issue, at least in my experience. I have tested this on both G5's and MP machines. Kontakt is unhappy as a standalone running alongside Steinbergs The Grand 2 also running as standalone, sharing a 2408 driver. VE not involved here - I get crackling on The Grand 2, and/pr total silence from Kontakt 2. Depending on the weather.

VE, on the other hand, runs as a standalone alongside Cubase 4.1 on a MP sharing a 2408 driver wiothout issue, although, thanks to the fact that I run at 48k, Cubase's own little bug rears it's head as it launches into 44, sometimes disabling everything. But this is a known Cubase issue.

Obviously, what I am describing is not exactly the same as your system or setup.

Hi Ben
if you get crackling that means that the audio interface is shared, you have problem of cpu power.

Since them I did more testing, VE K2 and Logic are OK if I load the VE thru Logic
So it is only when I load VE in standalone that there are problems
I have spoke to VSL programmer, he is going to have a look ;)
