Sorry, I don't really get what you are trying to do and you're not letting us know which software you are using for recording (Capture, Studio One), but maybe this document from the Knowledge Base answers your question: http://support.presonus.com/hc/en-us/articles/210047253-Studio-One-monitor-mixes-with-a-StudioLive-classic-or-AI-mixer.
With Capture there is no way to route the signal to any kind of monitoring. You hear the recorded tracks when you play them back to the mixer... The aux mixes and the main mix can be used as normal, there is no latency of signals because the computer is only streaming audio and not processing audio.
