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.
