I’m running the 32 bit version of Cubase 5.5.1 on an i7-system and 64 bit Windows 7. I also have C5 64 bit installed. My soundcard is a Lexicon u42s.
A couple of days back, Cubase seemingly reset itself from one day to the next. No current projects were remembered in the startup splash screen and several utilities had to be re-enabled, like my Presonus Faderport.
Since that time, I have been having some pretty strange latency issues. When I open up a recent project, that existed before the reset, and plug in a guitar or a microphone into my u42s, the response time from Cubase when I click on the monitor icon on the input channel, is something like 150 ms. This is with the highest setting of the soundcard ASIO driver (which is the latest version). With a more relaxed setting in the driver, the latency is even worse.
However. When I open the same project in the 64 bit version of Cubase 5 on the same system, the problem is not there anymore. Likewise, if I start an entirely fresh project in either the 32 bit or the 64 bit versions of Cubase 5, there are no latency issues whatsoever.
So it seems theses problems are directly related to these particular projects, and not only that, but these projects in 32 bit mode.
I tried reinstalling Cubase 32 bit, but that did not help things. I’m at a loss as to where to go next in my troubleshooting. I’d be grateful for any ideas. The thing is, I’m in the middle of an album project with a deadline just 8 days away.
