Hey everyone,
  Needing help again.. I'm putting together a system for a show in Branson. I'm needing to get the smpte time code from Qlab into a wholehog 4 Road hog light/ video console.   

I'm kind of new to the MTC and smpte thing.  First of all, has anyone utilized the wholehog console in correlation with Qlab. The lighting guy is requesting analog smpte through an xlr to be converted through a Highend widget for USB input into the Wholehog.  What is the best way to get this from Qlab?  My current plan was to get the Motu 828 MK3 as my interface.  

In the summary on this interface  it says, "The 828mk3 is equipped with Direct Digital Synthesis (DDS), a DSP-driven phase lock engine and internal clock source that produces imperceptibly low jitter characteristics (below the noise floor), even when the 828mk3 is resolved to an external clock source via either word clock or SMPTE time code. The 828mk3 can directly resolve to (or generate) time code via a dedicated quarter-inch time code input and output, without the need for an extra synchronizer."

So according to that, I would think that I could send MTC smpte cues for each song out of Qlab into the midi input of the interface and set it to convert the MTC to analog sempte, via the 1/4" timecode output, to get to the lightboard?  Does anyone know if this would work? And if it does, Is this the most efficient and effective route to go. Also please not that this 1/4" smpte out will also be run into a switcher to correlate with an exact replica redundancy  system.    If anyone has any experience with this or any ideas, please advice. 

Thank you very much and God bless.

Hey Colt,

If it were me I'd stay away from the MTC - SMPTE solution - one more
thing go wrong. Just have each smpte cue as a discrete audio channel.
It will also work better and more foolproof through your switcher.
Otherwise to send midi you need to add boosters, and use converters to
run them through the D-Link plug (assuming you're on a radial for
example).

Use your daw to generate the SMPTE audio tracks. WIth your motu you
get a program called MOTU SMPTE SETUP. Use a patch lead from the
SMPTE output back into an input of the 828 mk3 and record it. Make as
many cue as you need starting every 10 minutes or so for example...

Then for me I chose to use Logic's multitrack audio output to keep
everything super simple in terms of dropping files and sync within
qlab. So I had SMPTE on 1, Click on Two and the other audio bits and
pieces on 3-8, though of course you can use other programs to make up
to 16 multitrack channels.

email me off board if all of that sounds crazy,

Hey Chris,
This pretty much EXACTLY the I do it as well, and I agree, its rock solid. On the other hand, there are always options that can yield good results. Talk to you soon.
