Having finally set up my big template, I'm just testing it with some MIDI from DP8.

All my software is 100% up to date except my Intel Mac Pro which is running OS10.6.8.

I have DP8 running on the Mac Pro 2007 (8 Core, 28GB RAM). A VE Pro Interface in DP is connecting to:

Mac Mini (Dual 2.7GHz, 16GB RAM) running 64-Bit VE Pro Server. In it are loaded 3 VEP instances (Strings, Perc, Kbd). Each Instance has Multiple instances of Kontakt 5 and G-Player. They are running a combination of Cinesamples, Cinematic Strings (in Kontakt 5), and Giga sounds (GPlayer).

Although the templates are very big, my Activity Monitor shows 3GB Free, (with 3GB Inactive = 13GB used).

I'm trying to play some consistent rhythmic, staccato chords from Cinematic Strings (in K5 on the Mac Mini). There is one track playing some 5-7 note chords. That's it.

I'm getting consistent audio crackles. Sounds like a processor thing, but not sure...

I've tried a combination of tweaking Multiprocessor support (in Kontakt 5), Threads in VE Pro Server (tried 1-4 threads) and the instrument Prelooad buffer size tried 12Kbps-30KBps). Kontakt Memory Server is OFF. I'm still getting the problem.

Can anyone suggest what the issue is and what else I should try tweaking?...

thanks!

UPDATE:

I thought I'd post this for other users of VEPro 5 with Kontakt who may be having similar issues:

I was getting bad audio crackling. Especially when it got to be higher polyphony (e.g. big chord hits etc).

I experimented with multiprocessor support and this is what seems to have happened:

I was under the impression that I should DISABLE MP Support in Kontakt, since VE Pro handles it. I did the following:

1. I tried changing the Default Thread Count in VEP (from 2 to 1, 3 and 4). No change.

2. VEP says that enabling MP support in Kontakt can cause problems, so it's always been disabled. I tried ENABLING MP support in Kontakt, and set it to 2 cores (since I'm on an i7 Dual core).

Audio Crackles have stopped!

So far so good...but none for the past 30mins!....

Anybody else have MP support enabled (but KMS disabled), and thread count the same between Kontakt and VEP ?
