I have my analog four working nicely with ableton via Overbridge, however, there is one thing I haven’t figured out yet. Is there a way I can work on my sequences on the analog four independent of ableton? i.e. Press play on the A4 and work on my sequences without pressing play on live? Currently the transport controls on the A4 are disabled. It’s a small thing but would make my workflow that little bit better 
…the ‘problem’ is that Live sends start/stop via sync port.
Try this to filter out the transport commands.
