Hello Andi,
Here are some details of my machine: I am using Windows 7 enterprise SP1 on a i7 2600K @ 3.40 GHz with 24 GB RAM. I am using Finale 2011b.r2 and VE Pro 5 5.1.12684 aug 23 2013. I am getting the worst clicks and audio dropouts with a simple score which has only 3 VIPro instruments, two saxophones playing melodic lines and strings playing whole notes chords. At every bar there is a dropout. I noticed that the audio drops outs started when I added the strings instruments. CPU usage is very low 34% and also memory usage is only 4.81 GB of the total 24 GB. So it is not definitely a hardware issue. With the regular VE I didn't experience any issues, even with more complex scores. Also, I don't experience any issues using Sonar X1 instead of finale. Thanks for any help you can provide.
Best regards,
Gabriel.
