Logic 9 + MTC + MIDI cycle record broken?

Hi Logic folks...


Here's a doozy of a problem we cannot seem to solve. My friend and I have successfully sync'd our computers. However, we cannot seem to MIDI cycle record on the slave machine without Logic ALWAYS merging the data. 😕


He sends MTC to my computer, which detects it and locks on. He can cycle, and mine triggers and follows him just fine. Once triggered, my computer sends MIDI clock to my rack equipment, with no problems whatsoever. We both can successfully record both audio and MIDI, as well as play them back simultaneously, on both machines. He records his V-Drums, I record keyboards, along with varied accompaning musicians. No problem, Logic handles it.


When recording MIDI during cycle record, the Logic default works as expected, constantly merging MIDI data into this one region, as it is received.


If I choose one of the other options -- such as "Create Take Folders" or "Create tracks in Cycle Record" (with or without mute) -- Logic will record as expected, as long as I start the recording manually. [The above opions are in Settings --> Recording --> MIDI --> Overlapping Recording]


HOWEVER, when triggered by incoming MTC, Logic seems to ignore these settings and ALWAYS MERGES the MIDI data into the same region! 😢


So... CAN it be done? Can you trigger Logic with MTC and use the MIDI cycle record simultaneously?


If anyone has gotten this to work, or has any suggestions whatsoever, PLEASE post! 🙂 Our setup is SO CLOSE to being perfect, it hurts!


I've scoured the forum here, but can't seem to find anything... I apologize if this is a redundant post.


Thanks,

To clarify a bit more...


MTC is time based, hours, minutes, seconds, frames..etc. It's the MIDI version of SMPTE.

A cycle by it's nature backs up and starts time over again, this is not how MTC works.


MIDI Clock is based in pulses per quarter note, it is beat measure based, cycle record can return to measre xx and pick up again. the bad part is, as of version 8, Apple removed sync to MIDI clock, mainly because it's unstable for audio, the resolution is not fine enough.


I'm fairly certain that's your problem. I don't know if there's a work around.

Thanks for your reply, Pancenter. 🙂


I believe you have nailed the cause of our problem correctly... I suspected as much all along after having read that Logic strips MTC messages bare of positional information.


We have attemtped to circumvent this using MMC; but to no avail.


It is unfortunate, but I guess we'll just have to manage with crafting a single region on-the-go.


Making sure I have this right... and also to summarize for interested parties:


There is no way in Logic Audio 9 to synchronize iterative MIDI cycling between two computers running Logic in a master / slave configuration, because the slave cannot receive MTC positioning information.


Logic will ALWAYS merge the MIDI data into one region, and there appears to be no way around this... or is there? None that I know of, but if ANYONE figures out a way, please let us know!

Actually, it because MTC is linear time and cycle recording is not. Even if MTC sent positional information it linear clock would not match.


MTC syncs to a linear clock running hours, minutes, seconds frames (for video, that's what it was developed for)


Cycle recording by it's nature is not linear.


Basically, it's the wrong format for what you're trying to do, what you need is MIDI Clock with "Song Pointer" enabled. You could try Using Logic v7.2 or higher on the slave machine. It has the MTC sync option.
