I found a solution. Live 10 can simultaneously receive MIDI clock from LUNA and transmit MTC through a third party app called LIVEMTC. (https://www.showsync.com/tools#livemtc ) Using the trial version of LIVE 10 (my live 8 couldn't run the MTC Bridge plugin. The procedure worked for me as follows
1) Open LIVE
2) Add the MTC plugin to one of Live's channels,
3) Open the MTC app so that the app and the plugin link. The plugin will display a chain icon to signal that the link from plugin to app is established. (The app creates 2 virtual MIDI channels.)
4) Open Logic then LUNA.
5) Set LUNA's MIDI Clock output to an IAC bus and enable LIVE's SYNC midi input to that same bus
6) Click the EXT button at the top left of the session view in LIVE so that it's transport slaves to LUNA's.
7) In Logic's sync input SETTING shown above, select one of the LIVE MTC app's virtual channels. Make sure Logic's fps matches the fps in the LIVE MTC app. The fps is a user selectable preference in the MTC app. I used 30fps. Logic may or may not notice any discrepancy of fps. Logic may also ask several times which fps you want.
8) BE SURE TO SET THE TEMPOS TO THE SAME SETTING IN ALL THREE APPS OR LOGIC WILL STUTTER.
I was able to run all three programs with all three programs sending their audio out to my UAD Apollo for monitoring. It can take about a measure and a half ( I was running a 74bpm song ) for the sync to really lock in. So starting a couple of measures before any events is a sound practice. Finally, I routed both LIVE's and Logic's output to my UAD's virtual channels. So two channels of Logic streamed in on separate tracks and LIVE streamed in on a third track (for three separate stereo tracks of audio.)
One thing I really liked was being able to disengage the external sync in LIVE. Checking or unchecking the EXT will allow you to run LIVE's transport manually and check your sync to LOGIC. So I could let LUNA go idle, while working in Logic and LIVE with Logic slaved to LIVE via the LiveMTC bridge app. Same with Logic, disabling the sync mode meant I could work independently in Logic using its transport without the CPU weight of the other apps. Then when ready, enable the syncs and stream the audio. I only tested streaming audio into LUNA but it should be simple enough to stream the audio to either of the three apps from the other two. Hope this helps.
