If a preset using the Virus Inputs is loaded in Virtual Control, a latency of about 20ms (I measured 892 Samples several times) is added to all sounds coming back from the Virus Control plugin.
It's not clear whether that latency should or could be compensated by the Virus Control plugin or Cubase.
