Recently I had posted a question roughly about the sonic differences and qualities between using the hosts native mixer vrs. say an STM2448. I always use the STM2448 as my default but never exdtensivly used the CW mixer to buss every sound to it, I always just used it for CW deviced like synths and a few tracks I had bussed to the mixer that I was usuing effects like delays, chorus, vinco, interpole etc etc.
During that that in the thead there was no real deffinitive answer given regarding the sonic differences, a few ideas thrown out to conduct tests, but to be honest I am not as scientific as I would like to be and am more of a (if it sounds good to my ears) type.
So recently I had read a thread by Noah(thalamus), who explained he decided to mix entirely in SFP and was flawed by the summing of the STM, so I finally decided to create a project that could almost entirely bypass the Nuendo mixer, it still creates tracks for each sound and can also controle aspects like EQ, volume, pan laws etc, but I have it so every single sound goes to its own channel or group in the STM2448 via Asio2 ltf 64.
I gotta say in a non scientific test manner, to me everything just sounds more transparent, almost like the Nuendo mixer was adding distortion or some kind of compression to the master buss, now routed thru the STM mixer, things just sort of have more room to breath if that makes sense, its hard to place my finger exactly on it, but the sound is just clearer, pronounced and sweeter.
From here on, I will always make full use of my mixer channels hehe, nothing im sure many of you dont already know, but I think I finally just stepped things up in sonic quality in my mixes by a good margin, a track I am working on right now just sounds great with the new routing, everything is so spacious and clean sounding in in a state of bliss..
Anyways, just wanting to share my random thought for today

Cheers!
