[BUG] Preset with input processing adds latency to Virus Control audio

  • 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.

  • Marc, you contradict the answer from Access Support


    Zitat von Access Support


    Using audio input processing presets with the TI will add additional latency to a signal and you have to manually adjust this in your sequencer program. There is no way around this.


    An answer, which also leaves quite a few questions open.

  • i don't think it contradicts at all.


    You say "Virus Control doesn't add latency. That's the host". Support writes "Using audio input processing presets with the TI will add additional latency", no mention of the host adding it.
    Also, why should the host add latency for a signal that's externally processed?



    there are no open questions: if the latency is not compensated by the host, there is nothing that can be done.


    Questions:

    • Why is the latency on ALL parts, and not just on the part which does input processing?
    • Is this latency added by the Virus Control plugin to align internally created sounds with processed sounds?
    • Is this latency (of all parts) also there of the Virus is not used with Virus Control but in Sequencer mode?
    • Is this latency (of all parts) also there of the Virus is used in MULTI mode?
    • Why is the latency not compensated by the host? Obviously a host can only compensate for what is reported by a plugin. Which in turn means, VC should inform the host.
    • If this 20ms latency is to be expected whenever using input processing, why is it not mentioned in any documentation?
