AU midi record is possible if you have latest Audiobus 3
Ok so I stuck Autony AU in AB 3 (beta version) midi send slot, choose virtual midi bridge out in AB3 midi receive slot. Sent the midi across to a blank track inside NS2 and then used a send out from that track to Obsidian. Hit record and the midi is recording into the Obsidian track from Autony AU inside AB3 beta. So it can be done.
