but on any system that does send a locate command, such as one that
sends MMC, the time location is invariably specified via timecode,
typically SMPTE. this is appropriate when the only conceivable locate
targets are film/video frames, but this is not true for systems
dealing primarily with audio. i don't find SMPTE acceptable as a way
to share the position on an audio timeline.

i've been told by a company that specializes in timecode and shared
transport control systems that ardour has the fastest and most
accurate MTC sync of any DAW. we get down to about 2 samples of
jitter. that doesn't alter my observations about an audio timeline.
