I understand your post very well and i am also -sorry- pissed due to the behaviour of DIRAC in the last months.
So i stoppted using DIRAC. Instead i purchased Acourate, created Acourate filters (you need a windows PC for this), put these filters into Roon convolvin engine; and in this way Acourate is also usable on a MAC.
Sounds even better than DIRAC, no more fiddling and stress with the non working DIRAC software.
Okay, i had to pay again for a room correction software. Anyway: now i am ready and everything works fine.
