hello all

i'm a new user of RME products having just purchased the Digiface USB for PC. I must say it is great!
I had been using my Focusrite 18i20 and attached Octapre ADAT. The performance was not good. Using Cubase 9 I was unable to get below 512 samples, with poor latency as a result.

Using the RME, 256 works well at 48k 24bit. I have put the RME on it's own USB internal hub.

I wanted to ask a question about the new interface and how it works with the Focusrite 18i20

Currently I have the focus rite control mixer software installed and the focus rite attached with USB.
But do I really need this? as the Octapre seems to work and its not directly connected to the PC.
I don't require and specialist routing or sub mixes, just IN and OUTS.
Even if I do need some sub mixes etc, can I just do this with the RME total mix?

I am just getting a bit confused with the two sets of software and connections

any help appreciated

regards
Alan
