Thanks for the link. I looked at the code and docs. I couldn't easily
figure out if it can slave over midi. I need automation during recording
i.e. no UI. To be honest I am more comfortable with C/C++ instead of
I did however stumble across ltctrigger. It does exactly what I imagined I
needed in my first post in this thread via C system calls:
/home/robert> cat jt.conf
01:22:58:00 /usr/bin/mplayer /home/robert/star.mp4
/home/robert> /usr/local/bin/jltctrigger -vF jt.conf
Parsing 'jt.conf'.. 1 entries.

1) Staying on topic, can I execute ardour stop / play commands with system
calls? Just curious what I can do.
2) Via a jltctrigger system call I need to send midi start / stop with midi
clock to an external sequencer that doesn't support MTC or MMC (Genoqs
Octopus). Google isn't showing much that is recent. Can you recommend the
right tool for the job?
