The sends are the biggest issue for me, but nothing is perfect & everything is a compromise. Only 1 mono post-fader send, but there are workarounds with the sub mix, 2 monitor auxs & control room outs.
Midi sync is not an issue for me, I prefer a loose feel to tracks & very rarely quantize anything.
The big plus for me, is being able to record all the tracks that I want to at once.
I looked at other options, Zooms & Tascam digital options, but they seemed to only have 8 inputs. The Allen & Heath Qus were an option too, but meant menu diving, they are much more flexible, but for what I needed spending another £1000 seemed unnecessary.
I have recording format set to 48khz/24 bit as this is what I use in my DAW & recording quality is excellent & sounds indistinguishable from live feed.
EQs are very usable, no Neve or SSL, but fine (& recording is pre eq anyway).
I am very much into physical controls lately, so love the hands on simplicity of this desk.
I wish that the Monitor 1/2 auxes could be set to post fader, but apart from that it is pretty much perfect for me.
