Steinberg UR816C

I decided on this because my previous interface was also Steinberg, and I knew they had quality interfaces. Needed more I/O though and this provides a decent amount.
Build quality is excellent, everything feels good.
So far have used it in some mixing projects, pretty busy ones with 40-60 tracks including buses and I'm at half the buffer size of the old interface and using slightly less CPU, so happy about that!

Its easy to install, and very well integrated into Cubase as UR28M was but improved now with the C series software.

I got this mainly for using hardware fx as inserts. Its is a little bit fiddly to set up, but once you get it right its flawless.
The manual doesn't mention this at all.
Just need to in DSPmixFx software set the outputs of each Mix 1-4 to the DAW Direct outs 1-8. So Mix 1 (Physical 1L / 1R) will output to 1/2, and so on.
Then when adding your hardware fx you set the output to the DAW Direct number NOT the Mix or physical output. So if you output to fx with physical out 1L then that should be DAW Direct 1. Setting input is easy as the physical inputs are the only ones listed so can't go wrong there!

All in all very happy with my upgrade to this.

for this price range, this is great interface, easy to use, easy to install, I have it for some time now, signal is just fine, that latency that everyone are weeping about is nonsense, it works like charm, it has so many channels and conectors,even two jakcs for headphones, very friendly and easy software mixer, I still did not find and cons for this. knobs are beautifuly made and almost everything you use heave from your front side, I use Fl studio and works like charm with it, 32-Bit integer / 192 kHz and Recording / Playback Channels 16x16 for this price? omg who ever gave this baby low rate, he should consider it again, Strong advice, guys this is 650 euros huge interface, and it has world clock in case you use it, because why not :D
