Yes, it can work but not always. It depends on a few things. Mostly not all MIDI device drivers are "multi client", I think most of the new ones are, but devices that are over 5 years old may not be. What this means is that one application (Live) will try to open a MIDI device and another application (Mobius) will try to open the same device. Sometimes this may fail and Mobius will report an error, sometimes it succeeds but you'll have weird results because the MIDI inputs aren't being duplicated for both Live and Mobius. If you reconfigure the host application and close the device Mobius will still be using it and it may crash. If you want both the host and Mobius to open devices it is best if they don't open the same ones. You can control this in Live, just don't select the devices in Live's configuration page that Mobius will be using. Other hosts (like Mainstage the last time I checked) don't give you this option, they open everything whether you need it or not. The IAC bus on OS X is a special case as are PC alternatives like MIDI Yoke. You shouldn't have a problem with those if both Mobius and the host open them.

I'm sending clock from mobius via the iac bus back to Live as well.
