Hi all,

Any Cubase/VE Pro wizards out there?

I'm on Windows 10. With as little as 10-15 midi tracks with midi CC data (CC7, CC11, CC1) playing simultaneously, Cubase starts studdering and lagging trying to go over the regions with data and basically almost freezes. The lag is caused by how much MIDI data is going through. The audio keeps coming through with no pops or clicks, however, it becomes impossible to do anything because of this lag. As soon as the playback is stopped Cubase goes back to functioning normally. We tried going through all the possible Asio or Cubase preferences, no luck. Then we thought perhaps it might be a graphics issue, so we tried different Nvidia parameters on the control panel, no luck. The CPU usage in Cubase is about 10-15%, the CPU usage in the task manager is about 10%, the disk performance meter is at 0%. Even changing the buffer size of the RME interface from 512 to 2048 didn't improve the performance at all. We also tried going back to various previous versions of Cubase, no luck. Even if all the VE Pro instances aren't connected to the other computers but are just present in Cubase, the issue still persists. The issue goes away as soon as I turn off all the VE Pro plugins in Cubase. We tried all the buffer settings on Vienna, no luck. Tried uninstalling and reinstalling Vienna, no luck. Made sure that all the .dll files are the correct ones. Tried opening the file on Mac, the same issue persists. This problem occurs the higher you go in port numbers and gets consistently worse as you increase from midi port 1.  It's hard to believe that with just 10 midi tracks with data Cubase is basically unusable, so there must be something within Cubase/VE Pro that's causing this. Any thoughts?

Many thanks!

Same problem here on Cubase 11, VEP 7, Berlin Woodwinds.  Cpu is arround 10 to 20 percent.  But Gui is very laggy. 

Asio guard is already switched off.

Hi Davka, 

Thanks for the video! We're scratching our heads a bit here... 

A few questions: 

1) Did you try this with instruments of Epic Orchestra 2.0?

2) How many audio tracks are you routing back? Did you try with less audio channels (Preferences)?

3) Which CPUs are you using?

You can also send us the Cubase Song to check on our machines:

A quick reference to this thread will help!

Hi, 

If two optimization systems are competing over the same optimizations, it will slow down the system. So we suggest to let VE Pro do the heavy lifting.
