Default Re: Pro Tools Midi Sync Issues with External Device as Master - 2 second delay on sta

Post some other screenshots:
Peripheral setup -- first two tabs
Preferences, Synchronization Tab.

But here's some general info: MTC sync takes a minimum of 4 quarter frames to sync. That's just how the positional SMPTE reference is communicated via MIDI to get the full info. If you want to drop in on the very first second, it won't work. One of the reasons (besides allowing pre-roll for transport lockup) not to start at 0.

You should use MMC in conjunction with MTC. Your recorder seems to support that. MMC give transport functions so can operate immediately (why MMC is/was used for aligning tape machines/playback). MTC aligns timecode. MMC starts/stops relative transport. If you are already aligning manually (starting both the session playhead and your recorder at the same number) MTC is pretty much not needed and only MMC is. It's close to the way it was done in the olden days (everything was set to the right position and then one MMC controller managed all the machines)

What is your frame rate set to? For an external device, though I don't know the Roland, 30fps seems odd as most would have to deal with cycling issues (so would actually be 29.97). Make sure those match for the session setup. (Timecode Rate is the one that dictates that -- not feet+frame or Timecode 2)
