I have not heard of any reports of users not being able to use the trio with CyberSync. I am not intimately familiar with the Trio, but it either has to have a hotshoe (all images i have seen have a hotshoe, but there may be a configuration that does not) or some type of sync terminal, or both. Since it does not have a sync terminal and does have a foot, you can use the speedlight foot adapter (SLFA) to attach to the foot of the Trio, then connect to the reciever. You can find the SLFA as the last item on this page:
