Also, I usually use an ADAT loop to route audio from VE2 standalone back into DP, but I have used soundflower and found it to be pretty reliable.

Latency is 512 (x2 on VE server), samples are stored on an internal SATA hard drive.
The jitter also occurs after a fresh system boot.
I understand Soundflower isn't mandatory to get the audio back into Logic with a Fireface, as its inputs and ouputs can be toyed with in the soundcard's matrix. So if I can avoid using yet another software layer, I will... But then I guess I don't get the ticks inside the matrix right (anyone with a screenshot?)
About the ADAT loop part, I have 2 i/o's on my FF800, and no combination I try gives me any result...
Unless there is a small glitch that I can't put my finger on somewhere in my setup, I do feel like an utter idiot right now (unpleasant feeling)...
Thanks for your time.

I don't have a Mac Pro, but my machine is very similar. Obviously using Windows I can work a different way, but at the moment I am using anything up to 100 Instruments (usually not more than 60 at a time though) without any breakup. This is at a buffer of 128. for more dense orchestration I have to raise the buffer to 256 for a clean, pop-free playback. If you are getting much less than this then your system doesn't seem to be working as well as it should.
Let me know if you want me to test anything on my system.
If this has been of no help, then just ignore me. As someone who used to earn their living from conducting, I'm used to it. [:(]

I gather you're on a 64bit copy of Windows then, otherwise RAM allocating issues would simply prevent you from loading that many samples (unless you open discrete standalone instances of VI?).
If that's the case, then it could mean the problem comes from the 32bit limitations on our side. So hopefully this will all be water under the bridge in a few months.
By the way, the renegade core does calm down if I hit stop and get back to zero after having the CPU meter peak while playing several VIs in a row. I can repeat this endlessly. Now that to me looks like a bug...
I haven't had time to give another try to the audio looping issue concerning the MIDI through IAC workaround, but I'd still appreciate someone sending me a screenshot of their Fireface matrix setup if they can provide.
Many thanks

AFAIK Logic allocates one core for each VI instance. If you are using Vienna Instruments this should not be a problem, but if you are using Vienna Ensemble it may be that you are just trying to do too much for only one core. Do things improve if you increase the number of instances?

Thanks for your quick answer DG. Memory's just fine when the problem occurs, and everything gets back to normal if and when I hit stop and rewind, until I start playing a number of VIs again. This a one track / one VI template, I'm not using VE plug-ins.
I'd be interested in a feedback from someone in the VSL team on this CPU peak thing.
Thanks again

Hello 9u10m,
Can you please send us your template where this happens? (support [at] vsl [dot] co [dot] at) 22 Instruments were doable on a G5 2.5 Ghz.
On a MacPro 3.0 Ghz we had 80 Instances playing without any glitches.
Btw, I just had the RME Madi card for a long time but no FF. I think you can use the FF Matrix OR the Loopback option to route the Audio back into Logic.
Have you tried to keep the Matrix empty and only use just an Adat cable?
I assume that the analog ins and outs are numbered from 1 to 8 and the Adat ins/outs start at channel 9.
Now set the Driver to FF in VE Prefs and in Logic, set the output from an instrument in VE to out 9-10.
In Logic´s mixer you create an Aux channel (cmd+alt+n) and set the input of this Aux to 9-10.
Voilà, now your audio signal from the instrument in VE is routed to the Logic mixer.
Attention!! Be sure to "kill" the IAC-Bus midi ins in the "Clicks and Ports" Environment of Logic.
IAC-Buses are ins and outs at the same time (No specific ports for midi in or out are available for the IAC´s)
This is a much more CPU gentle option to handle the audio compared to Soundflower or Jack OSX.
I hope we can solve this quickly.
best,
christian

This is not my experience with VI in Logic 8 / MacPro 8x2.8ghz. If I am ONLY playing back already pre-recorded MIDI the Mac distributes the load evenly across all 8 cores. But as soon as I select any of my VI tracks to record a new section, the Mac immediately shifts all the load to one processor, which usually causes peaks.@DG said:
