Not sure if this has been discussed yet, but I was just looking at the midi control parameters that were added in 1.1 and noticed Crossfader - CC#48. So I plugged a midi cable into the OT's midi in and out, made sure there was no sync or transport being received, and set audio cc out and audio note out to INT (not sure if this part is necessary, but I do it anyway). Set a midi track channel to an audio track (doesn't work if set to autochannel), set a CC knob to 48, and automate/p-lock away.
You can do the same with scenes to get even crazier (scene a-cc#55,scene b-cc#56).
