I've searched the forum for this issue but I haven't found anything.
I have my template already set up with 9 instances of the VE Pro plugin (7043) in my Nuendo 5 VST Instruments Rack.
Then I added other three plugins (Addictive Drums, Omnisphere and Stylus RMX).
Now I need to add a new instance of the VE Pro plugin, but when I try to press the CONNECT button, the plugins shows up an empty "Available Slaves" list (neither the "New instance" is visible).
I tried to turn off (not remove, simply turn off) every plugin but the new one, but it didn't work: the "Available Slaves" list is still empty.
Then I tried to remove "Stylus RMX" and after that the list of the available slaves showed the unconnected instances + the new instance.
I loaded a new instance of Stylus RMX and the list of the available slaves is empty again.
The same happens removing Addicitve Drums and/or Omnisphere.
May somebody explain what causes this problem?
