Hi, saw the previous poster also had an issue with Ultrachannel delay sync. I'm on Protools though.
So even when the Sys Tempo button is lit orange (on?), the tempo doesn't follow the session tempo, needs to be entered manually.
However even when the tempo is correctly set, the Delay amounts cannot be adjusted via the knobs. They're stuck on 250ms and can't be moved, unless Sys Tempo is turned off.
