Hmmm...
Not sure what to say here...
About two months ago, I found an old file/sequence in Sonar that I'd worked on many years ago, and since I don't work in Sonar anymore and work exclusively with Samp Pro X Suite now, I wanted to transfer the external midi info from a Proteus Sound Module to audio tracks in Samp for further production.
I imported the midi tracks into Samp, made sure tempo was set correctly, set Samp as the master for MTC, made sure the external midi tone mod was set to receive the data; ( I also allowed two measures at the top of the sequence due to past experience with MTC "chopping off" the first few notes of a sequence if started precisely at 01:01:00) - and everything worked fine... no drift, no pauses, no glitches...
I was able to do 8 different passes for 8 different/discreet tracks, and I didn't have any issues at all.
The thing is, because I've only ever done it one time with Pro X Suite, ( it's just not something I do much of anymore in my production workflow), I don't remember exactly what I did, or how I had things set - other than what they would "normally" be set for when working with MTC.
(I'm using a Presonus 1818VSL as my main midi I/O).
I'm just throwing this out there....
If you are having the same issues in Logic too, I think I'd be looking at your interface, or even perhaps your external midi device as more of the source(s) of the issues. If you've tried three different DAW platforms, and none of them are able to get your midi to respond to the sync code, then I'm not sure the DAW's are the problem...
Are you using USB-based Midi? Or "standard" midi?
Have you made sure that your versions of Samp//Magix are all up to date, patch and bug-fix wise?
Have you made sure of the same thing with your audio/midi interface drivers... not just software, but firmware, too, if applicable...
Have you made sure that your external midi slave device(s) are set to Rx and sync to the incoming MTC?
Finally, have you contacted Magix about this? You should file a support ticket. They really are very good with helping to resolve issues... if for nothing else than to perhaps determine that maybe it's not your DAW platform at all, but instead might be your midi I/O or your external midi device(s)...
FWIW
