So I try again here: did you check if C7 uses all processors in your computer?
In my case (i5 mac with 4 cores) just 2 out of 4 are used although "Multi Process"is enabled in VST Audio System. If the latter is disables just one is used.
[please see details and screenshots in my previous post in this thread]
Just because you have 4 cores on your system, does not mean Cubase just gets all those 4 CPU's. I am not an Apple wheenie so I am not familiar with OSX but in general, an OS and its task/thread scheduler itself as well as other applications and services needs CPU too. Depending on how this all cooperates internally with hardware and software resources, Cubase gets alotted a certain amount of CPU resources at any one time.
In short, just because the Multi-Core checkbox is checked, does not mean Cubase automatically gets all CPU resources.
Also, four cores does not equal 4 times the horse power of a single core. There is various administrative costs associated with cores cooperating. Multi-core processor
Other factors to consider is just how Cubase is using its multi-core option. It could just spawn a second thread, or it could run parallel code, or variation of both, and so on. If you are using plugins (which is to be expected) they could be multi-core enabled too, which would affect how the system allocates resources.
Don't get *quiz* here, but I do find it interesting that most customers assume that a new version will be able to run a C6 project. Maybe the internal architecture has changed and the same amount of features cannot be squeezed out of the same hardware. Just because it used to be possible to run X amount of tracks doesn't mean it is still the case, depending on the Cubase changes for C7 and how your plugins affect C7 (even the ones included with C7).
Steinberg might even have to raise the minimum requirements for its products.
