Hi all,
Hope you don’t mind the thread jumping topic a bit here:
I have a cheese grater 5,1 / 12 core full RAM, and I use Pro Tools 12.5 HD software with symphony Mk1 usb in a hybrid summing studio. (SSL Sigma)

I find the system unreliable, lots of crashing, no side chain comp and phasing issues crop up when sessions grow so I was thinking to get an HDX card for it.
Also noticeable delays when recording automation.

I’m is there any can advice on what I can investigate in order to keep the 5,1 going for this? It isn’t flashed.
Also I understand I can just buy the HDX and link to via digilink to the symphony Mk1 (I don’t think I pay the Avid licence for using it because I’m on 12.5 HD software and Avid state it’s for 12.6 and above). Is this correct?

Thank in adv.
Phil
