Recording on machine or to the computer, or both?

🙁 Ok, I’m using a Zoom H6 right now that seems to work very well, but dog-gone-it, I can only record 6 separate tracks at once.. I’d love to get the U-24, but my budget is eyeballing the LR-16. Seems like a great little unit. My main question is: How about setting the levels on it for live recording. Other reviews have given negative reports on that end of things, but I guess I could just use it as an interface from my analog Soundcraft board and got straight into the computer to a DAW program. 🙂 Now the b i g, question is: can you do both at the same time. OR, can I use the computer to set the levels for when I’m recording on to the unit itself? How’s that for a couple of ignorant questions, only, I’m really not sure here. Any help would be appreciated. Marc Trainor. .
