Looking for live recording help

auti

I am looking into purchasing some new equipment in the coming months and need some clarification regarding the best way to record a band live - both at a gig and in the studio.

I am looking to buy a UA Apollo Duo and two RME Octamics ii

I am also considering upgrading my desk from an Allen & Heath PA20 to a Midas Venice 320, depending on what you guys might tell me here...

Basically, if I am to record a band live at a gig what is the best way to route each channel? From what I can figure out I have two options:

1. Each channel goes into the interface first then into the desk.
2. Each channel goes into the desk then to the interface.

I am concerned that routing everything via option 1 might create latency and also if the computer crashes in the middle of the gig I'm up s1t creek!! Does anyone know how audio is routed from the input of the above interface set up to an individual output? Will this be done through the DAW (probably creating a noticable amount of latency) or will the routing be done through the interface itself making latency an non issue?
Even if latency is not a problem, there is still the possibility of the computer crashing - if the audio is routed directly through the interface and the DAW crashes will this mean the output to the desk will remain unaffected?

The reason I am considering routing to the interface first is because my current desk - the Allen and Heath - does not have individual outputs for each channel, making multitracking impossible. If I were to purchase the Midas desk I will have an output for each channel alright but I wonder will the fidelity of the audio suffer?

By routing through the Midas will the desk's preamps colour the sound? Will that have negative impact on my recordings? Does the fact that all of the connections to the interface will be 1/4" jacks rather than XLR make a big difference? Finally, is this just the safer option to record bands during a gig, making a computer crash a non entity for the sound coming through the PA?

The DAW I'll be using mainly is Logic 9.

I'd really appreciate any and all help you can give with the hundreds if not millions of questions above!

Splitters are the best bet for something like this. I've recorded stuff before using a passive split multi in a venue that had the split for monitors and that worked great.

The thing to be careful with using the pre's on the midas and recording the direct outs is to make sure it's pre fader and pre EQ. Otherwise you'll record your fader movements and EQ for the gig on each channel and often thats NOT good for recording. Not sure if you can easily set the midas up this way, a quick glance at the manual will tell you though.
