Hi Owen
you cannot record from ACE.
To record all your mic pre signals from a GLD onto a DAW and play back for v-soundcheck you need an option card:
M-DANTE [you then install Dante Virtual Soundcard on your computer, route everything using Audinate Dante controller software, Dante has added benefit of audio networking to lots of third-parties].
M-Waves [allows you not only to access the wonderful world of Waves plug ins, but has drivers for multitrack DAW recording and playback to your computer].
M-MADI [you need a HW Madi interface such as RME coupled to your computer, Madi is also a universal interconnect standard]
