Not even talking about the issues you will probably run into with latency, dropouts etc, but you will have multiple ADDA passes which you really want to avoid. You don’t want to add color of multiple ADDA passes, one is ‘damageing’ enough. The way I use it is have multiple analog hardware in line with each other through my analog mastering matrix. I can switch in/out every analog device I use in any random order including MS.
My masterchain looks something like this most of the time: digital EQ (fabfilter pro-q or psp neon) > external gear (ADDA pass through analog chain) > ozone5 (some subtle things going on) > fabfilter pro-l.
The digtal EQ at the beginning is mostly just for cutting some stuff and maybe boost the level right before the analog chain.
So if you want to you use more hardware, get an analog mastering matrix, patchbay or plug things in series and use hardware bypass with relays to switch things in and out of the chain.
