Digitakt /OB - all velocities to 0 bug?

Have we covered this one? I’m running OS 1.10 on my DT, with OB on the computer and Logic 10.4.2 (High Sierra).

It works pretty seamlessly, but every so often the velocity (on the TRIG page) is suddenly set to zero, for all audio channels at once, so there’s no output. It often happens when loading a new project either in Logic or on the DT, but sometimes it just seems to happen randomly.

It’s a quick fix, as I can just do Ctrl-All and turn them back up again, but does anyone else get this? What’s causing it? A random message from Logic?
