So to illustrate the technical issues, here's an; albeit bad quality (sorry had to record it via the screen and not screenflow) video.
It is quite long (7 mins ) but please bear with it, and it's not the most exciting video you'll ever watch but it tells you what you ned to know.https://dl.dropboxusercontent.com/u/21946471/Arturia/Oberheim%20SEM_H.264_1mb_1280x720_16x9.mov
My install of Pro Tools is rock solid, not even a crash for weeks. Yes, the SEM and Spark do hang it from time to time but they always come back, even if I have to go and buy a coffee and let the beach ball of death sort itself out.
Graphic card wise, I have an NVIDIA GeForce GTX 285 Cuda.
In the video you can see I have a UAD DUO card which handles all my EQ,, Comp, Delay etc. The internal CPU is for running Pro Tools, Arturia Plug ins and AVId VI's have it all to themselves.
Please take a look and see what you think
The Obie is rock solid in standalone mode, no crashes at all.
