Strobes not firing when tethered

Robert Inn

Camera: Canon R5

Strobes: Profoto B10 with AirR\emote trigger in the hot shoe.

While tethered, the strobe will not trigger/fire when the shutter is activated from the Capture One capture buttons in either the tether screen or live view screen.  All other camera settings can be controlled from Capture One, including the shutter.  This is not a Canon-problem, because tethered shooting works just fine (including the strobes being triggered) when I use Canon EOS Utility just not when using C1.  Anyone else experience this?  I would think C1 would be interested in solving this problem since one of the main marketing points of C1 is how wonderfully it works with tethered shooting.

    I figured it out since Capture One support is non-existent (I put in a request for this issue 15 days ago and it's been crickets since).  My flash controller was set on 2nd curtain sync, which for some reason, doesn't fire the strobes with C1 tethered shooting, but works with Canon Utility tethered shooting. When I switched it to 1st curtain sync it works with C1.

    FYI high-speed sync (HSS) doesn't work with C1 either, so if you wanted to shoot with HSS for creative reasons, or out of necessity you won't be able to do it tethered.
