I'm a bit confused on how to get the most out of my gear. I have an 8 track mixer (LD Systems Vibz 8) where all my instruments (mostly synthesizers) are connected. The mixer main outputs are connect to the L/R line inputs of a digital recorder (M-audio Microtrack II) and the control room outputs are connected to my studio monitors (Alesis Elevate 5 MkII). I love this setup because it allows me to record any idea that may pop out at any minute with the just the tiny recorder and my mixing skills.
Now here's when i'm starting to get confused: i want to master some tracks that i recorded with the method above mentioned using a DAW (Studio One) and some mastering plugins (Ozone 7) on a Windows 10 machine. I currently use the 2-track stereo input to connect my computer to the mixer using the onboard soundcard output. Is this sufficient? Should i use ASIO4all as audio device on my daw instead of the onboard's one(Realtek ALC892)? Should i use an audio interface? If an audio interface is indeed preferred over the previous methods, should i connect it's main outs to the mixer or to the studio monitors ? Please bear in mind that i don't want to change the way i record my staff. I love my recorder's mixdowns. So if an audio interface's advantages over the onboard card are the inputs only , i skip it.
Please let me know what you think.
