Right, and I was involved with Robin in adding that capability to
Ardour. But, this doesn't help with something like an RME MADI card,
that doesn't have any analogue inputs, where do you inject the LTC ? I
also think the offloading of the processing of the LTC would be useful.

can't say how you get at the TCO input, but thanks to robin's recent
work, ardour can chase an incoming smpte ltc signal. it is just
another audio signal, connected to ardour's ltc input port.
fwiw, you don't need a TCO to chase LTC at all. the TCO is interesting
if you want to generate LTC in hardware, or if you want to _sync_ to
LTC, i.e. recover a clock signal from it.
Hi Adrian
Hi!
Let me CC Robin and LAD on this one.
