Linking the audio progress slider and MTC

[icthelight]

Under MTC (MIDI Time Code) Cues and LTC (Linear Time Code) Cues, the documentation says, "Also, if you drag the progress slider on the Audio File sub-cue, then the MTC will be adjusted accordingly."

Does this work? Are there any tricks to making it work?

See the example below.


the MTC sub-cue is shown as linked to the audio file sub-cue, and whilst playing the cue I clicked on the progress slider. MTC immediately adjusted to match the new position.

Thanks for your reply, Mike. I worked out that the problem in my show was that I set a Rel. Start Time of 4 seconds on the audio track to match the 4 seconds of pre-roll on the MTC track. When I removed the Rel. Start Time, the two tracks did become linked.

I suppose I could use a DAW to add 4 seconds of silent audio to the beginning of the audio track. Is there any other way I could synchronize the two tracks while retaining a short delay at the start? I need to give my lighting console a chance to sync up with the MTC signal before the song begins.

Is it a bug that the setting of a Rel. Start Time de-synchronizes the audio track and the MTC track?

Not really a bug but a scenario I hadn't considered. I'll look into supporting this shortly.
