Can you elaborate on how you experience the audio plugin not to work on a trigger ? What was the input reference ( match the audio of the input)?
Seems ok here

Try without having the audio settings window open when the trigger executes , open it after the trigger was performed


for that you need to select the onoff command one

Do you actually transition your audio track to output, i.e. cut / fade /...?

Also, be aware that delay is only working up to 30 seconds, see https://www.vmix.com/help26/Triggers.html. I'm not sure if it is the right tool for your intended outcome ("... apply plugins anywhere in the song...").

what is the exact goal you are trying to achieve with cantible and vMix ? i read some of your recent posts but wasnt sure.. are you trying to perform live music and have videos triggered as you play ?

OK.. i havent used cantible but i previously setup Reaper and OBS for similar task..

in Reaper i just placed a midi tracks alongside audio tracks on the timeline and setup midi CCs at exact locations which routed to OBS with loop midi driver.. the videos in OBS didnt play any audio, the audio was all coming from Reaper so i didnt need both applications to use the audio driver.. i dont recall any latency doing it that way and id imagine the same should be possible with vMix ?

Reaper can also automate plugins well so when you need to turn delays on/off or change specific FX settings on the fly its easy using automation items.. also easy to setup songs as marker points and entire set lists at regions.. it can send lyrics to a tablet also like a teleprompter and its super efficient CPU and latency wise.. given cantible is made for live performance id imagine you are probably able to do most of that already but if there is anything you are having trouble with id say consider checking Reaper out.. its so impressive how adaptable it is for applications like this..

personally i wouldnt want to use a virtual audio cable to connect two bits of software when you rely on the audio for the live performance.. its not that it cant work but the more interconnected stuff the more invitation to problems.. less complexity the better (esp mission critical)..

are you just wanting to send the video clips to a screen at the venue ? if so you shouldnt even need vMix you could do everything in one program (ie: Reaper), i looked at cantable website and couldnt see it mention any support for video but i recall seeing other live performance software that supports video..

if you want to stream the video then you would need vMix obviously but IMO it would be better to separate the audio from the video, play the audio back in cantable and trigger the video in vMix.. wouldnt that setup also solve your "how to turn FX on/off" question (if all the audio is in cantable) ?

if you are worried about sync drifting with audio and video separated, maybe try and see how bad it is ? you could always cut the video into a few sections and re trigger at different points in the song if needed..

if you are comfortable with the setup you have, all good.. just offering some ideas..

i'm pretty sure Reaper works with 4k video playback.. it uses VLC as its decoder so whatever VLC plays should work..

id say its worth checking Reaper out if you aren't familiar, it has lots of features that support live performance and its extremely adaptable.. the forums for it are helpful also..
