I'm running Digital Performer 7.22 on a Mac Pro 8-core 2.8 GHz with 12 GB RAM and Mac OS 10.6.7 as my master and a Mac Mini 1.66 Intel Core Duo with 2 GB RAM and Mac OS 10.6.7 as my slave. My versions of VE Pro on both computers are up to date. I'm running Kontakt in an instance of VE Pro on my slave. Everything works great if I only have one instance of Kontakt on my slave, but as soon as I add a second instance, all instruments routed from the slave, even the ones from the first instance of Kontakt, start glitching and popping. Activity Monitor on the Mini says I'm only using around 500 MB of my 2 GB of RAM and the CPU usage never gets higher than 50%, so I don't think the issue is overworking the Mini.
I'm stumped on what to do and any help on fixing this problem would be much appreciated. Thanks!
