Hi,

I have a strange issue and am trying to narrow it down to what it is. I have a 12core mac pro with 32gb of Ram and a Raydat card. Now i had a massive setup file with loads of vst etc etc and the buffer set to 1024 it does ok but decided to re do the setup file a different way (more efficient)

I started this by adding only about 5 vst instruments (Kontakt 5, Halion 5, Addictive drums, Supperior drummer and another ) Everything updated to latest updates etc etc. Now if i set all these instruments going at a buffer size of 256 it starts to spike and crackle etc.

Surely this isn't that bad as its nothing particularly stressful on the system. I have updated all hardware aswell (Raydat card included)

can anyone help at all?

many thanks
Joe
