Re: [sc-users] MIDI Time Code



Well, I'm assuming that the 'smpte' method of SC takes care of sending the appropriate 'quarter frame messages' per smpte frame. At least in theory. Can somebody confirm this?

Hi,

as I remember there are some specifics to MTC in in which order the messages
need to come, read here for details:

In the past I've used MIDI clock to run Logic as slave synchronized

'smpte' method. However, it doesn't seem to work properly.

in what way?
does it throw errors?
how are you trying to do it?

post some code and output messages...

Thanks for your interest. Here is my code

-------------------------------------------------------

~mtc = {| frm, sec, min, hrs, framerate |
	Routine({
		loop{
			if(frm==framerate){
				frm = 0;
				sec = sec + 1;
			};
			if(sec==60){
				sec = 0;
				min = min + 1;
			};
			if(min==60){
				min = 0;
				hrs = hrs + 1;
			};
			m.smpte(frm, sec, min, hrs, framerate);
			frm = frm + 1;
			wait(1/framerate);
		};
	}).play;
};

r = ~mtc.(0,0,0,0,25); // start
r.stop; // stop

--------------------------------------------------------

I've set the MIDI port m to the IAC bus of OS X which is received
from Logic. Actually Logic's song position line follows as expected,
but somehow the sequencer gets corrupted, ie. there is no sound
anymore until relaunch of Logic. I've also tried sending it to an old
reliable Cubase VST sequencer, but in this case the song position
line didn't even move.

I understand that MIDI is technology from the 80s but unfortunately
Apple's technology from the 21th century doesn't support OSC yet;) So
I'd appreciate any help to get MTC working with SC and Logic.
