A few post back I said the only slight niggle I had was that some plug-in instruments gave short hiccup when sounded/played for the first time in a project in Cubase 7 64bit.
I am happy to say I tracked this issue down and found a solution for this problem…
I seems that Windows Security Center/Windows Defender did not play nice when loading samples in some plugins. That behavior is fairly random. As an example: I had problems with Padshop Pro, but not with Halion Sonic SE (both 64 bit).
Anyway - I noticed a lot of disk activity when just running a simple project with only 25 soft-synth tracks (a lot of them used more then once so the total soft-synth count is only 8), 3 audio tracks and some FX channels. I do admit I do not have s super-strong system (i3-540, 8Gb memory, Windows 7 64 bit, Focusrite Saffire 6 USB), but it should run that project without even that slight once-only hiccup problem. So - time to take a look at the cause of the culprit. When taking a look in the taskmanager what application was accessing the disk that heavily, to my surprise it turned out to be the virus scanner service (Windows Security/Windows defender).
So - I uninstalled Windows Security Center and disabled Windows defender, and installed a much lighter virus scanner (I used Avast! free, but any light scanner would do). After that all my projects play without any hiccup or problem. I also noticed the VST performance meter no longer give any spike into the red and is on average a fair amount lower than before.
This leads to the following tip: If anyone is experiencing light stutter, hiccups, or small dropouts, having the VST meter sometimes spiking into the red etc. - and you are using Windows Security Center/Windows Defender, it could be worthwhile to install another virus protection. It is strange to see Microsoft’s own software is performing that bad, but I am glad I found out.
Oh - and by the way - I did not had this problem with Cubase 6.5. I can only guess what is the real cause of this small problem, but I think Cubase 7 is slightly heavier in use and/or Windows Security Center/Windows Defender is not playing nice with Cubase 7.
I am glad to say Cubase 7 is running great here. Until now I have not run into any serious problem (apart from the small thingie above). I certainly do not regret I did the update from 6.5 to 7. Now - back to work…
