Getting accurate midi from Ableton to Pro Tools?

[meech]

I was wondering if anyone knows how to sync Ableton Live to Pro Tools without Rewire.

I need to get midi I've recorded/edited in Live into Pro Tools for further work, freezing tracks to audio and exporting won't cut it for my needs. Ableton Live can't use 3rd party plugins or send out midi when it's a Rewire Slave, so I can't sync the programs this way.

I'm able to set up bus midi tracks out of Live with the IAC driver and record it into Pro Tools, but I want to get the timing as accurate as possible. Exporting midi out of Live also won't work because Live exports all midi out at 96 ppq. If I could get sample accurate (or close to it) that would be ideal.

I've also figured out how to send out Midi Timecode from Pro Tools and have Live sync to it, so when I hit play in PT, Ableton Live plays also, sends its midi out through the IAC driver, and Pro Tools records it.

The trouble is, the timing is not consistent enough. Perfect quarter notes in Ableton are 722 to 723 samples late one pass (when recorded in PT), but 769 to 803 samples late the next pass. Does anyone know how to get this delay compensated for, and get it consistent (remove the jitter)? Maybe I need to set the Timecode frame rate to something other than 30? Maybe there's a more accurate way to sync these two DAWs other than MTC? Could I get Reaper rewire slaved to Live, send midi with accurate timing there, and then somehow get Reaper synced to Pro Tools to send the midi?

For my purposes I don't need real time, perfectly timed sync between PT and Ableton, I just need a way to get that midi from one DAW to another without losing timing, so if I need to record it in real time from Ableton to Reaper, and then to Pro Tools, it's no big deal.

Thanks very much for the help!
