Syncing 2 DAW's on 2 different MBP's :Ableton Live and Logic Pro

Can't tell you much about ipMIDI but there may be other problems than just getting ipMIDI setup and running.

Logic does not Sync to MIDI clock, (which is tempo/beat/measure based)

There is MTC but the problem with that is MIDI Time Code is time based, as in hours/minutes/seconds, plus it uses considerable MIDI bandwidth.

You would have to go back to Logic version 7.2.x to be able to sync to incoming MIDI clock.

You can try sending MTC from the MD's system to yours over ipMIDI but it won't sync tempo, it will only read out seconds./minutes/hours. Logic will not lock to a tempo because there isn't any, only linear time.

However, if it worked without glitches your MIDI recording would be in time with the MD's Ableton performance.

There's the setting of time codes for each song and all that but it could be worked out.

I think I'd just set Logic to record and match them up be ear, there's got to be some focal point in each song that you can line up to. Good luck trying to do that it is not an easy task.

I play guitar/banjo/mandolin..etc in the pit band for most of the touring Broadway shows that come through town and was pleasantly surprised to see one of them using three separate "Mainstage" setups for the three Kurzweil pit keyboards. Worked flawlessly, was all setup by a New York programmer. I think I've mentioned that before.

So, If I am running logic pro 7.2.3, and i have Optical and S/PDiF connected, what do i have to do to make Logic Slave to ableton?
