Vienna Ensemble Pro Cubase 6 problem


I have a strange problem in the event when I load a Mac Cubase 6 session which opens a VEP Metaframe,
occasionally some instances do not respond, do not transmit MIDI or Audio, and act as if they are not connected, even though all instances appear to be connected.

The only way to remedy this is to remove the VEP Instrument Track, replace it with a new one, and “connect” again.
Reloading the instance, MetaFrame, or Cubase session does not remedy it.

I am using MusicLabs MOL, however, this problem does not appear with any other sequencer… DP, Sonar, Pro Tools, Cubase 4, Cubase 5?

Any input is appreciated

Are you using VSL in 64bit or 32 bit?

Are you running VEP on the same computer as Cubase?

Did you have another session previously opened before this happens?

Which bit version of Cubase and VEP are you running?

Do you decoupling the VEP instances normally?
