Hi,
Same problem (the issue of misohoza) here.
Also with Window 10. Halion 5 worked fine but since I updated to 6 the problem is there.
See Steinberg is working on it. Hope it will be solved soon.
By the way, it also occurs in Halion Sonic 3. But will be the same problem i think.
Once it will be fix in Halion 6, Halion Sonic 3 will probably automatically also be fixed.
Best,
Harald
P.S.
@Steinberg: Any idea when we can expect a maintenance update with these bug-fixes?
