The easiest way to do this is kind of a work around....
Take the Coolux SMPTE cable (basically looks like a USB to XLR cable - but it's not just an adaptor)... program what you need to program onto the timeline, tell it to sent SMPTE. Then what you'll need to do is find a device (I work with someone who has 3 of them) it's a timecode generator. It generates SMPTE, Midi TC and Word Clock, it also CONVERTS from any one of these to any other without losing any frames...
I don't know the name of the device, but I've left a message about it, I'll let you know when I know. I know they're not expensive at all.... he found one of his at a pawn shop for very cheap.
I've used this on shows and it's been solid, never had a problem with it.
Hope this helps... unless there is going to be a way to take Midi TC and Send it soon...
