Mobius arranges input channels into stereo pairs called "ports". It looks like Ableton does the same, though they give them confusing names.
Testing with Live Lite 8 on Windows, it appears that sending an Ableton audio track output to "Track In" on the Mobius track sends it to what Mobius calls Port 1, the first pair of stereo channels. Sending to "Left in 2" sends to Mobius Port 2, "Left in 3" to Mobius Port 3, and "Left in 4" to Mobius port 4.
But I can't get it to send to ports 5 - 8. This appears to be a Live limitation, at least in the "Lite" version I have.

(set the number for how many ports the plugin will show Ableton Live)
