Thank Jeff, that was swift response on Sunday, much appreciated.

I have HDX 2.

What I want to achieve is to use my DK(5.1) and RTW(2.0) AES/EBU meters together with MTRX Studio. Is this possible and can it be used without Pro Tools running?

I did try all three possibilities but no success. In the last option which drastically reduce the amount of I/O, from 80 to 32, but I did try and I made two Meter sets in mon. profile and send those to Digilink 25-32 where my meters are connected, I can see in DADman configuration matrix that there is signal coming in but the meters are not responding. What I see is that every time I close the Pro Tools, HD I/O clock jumps to INT 192khz. I tried many possibilities with Word clock from MTRX, (also changed to word clock base), from SyncHD...doesn't work.
