Send MTC quarter frame message

Hi guys,

Thanks for this great software.

I have successfully sent a MTC full frame message via /mtc timecode and a quarter frame message via /sysex msg. I learned the hexadecimal code of quarter frame from here. But when I want to send continuous quarter frame, I don't know how to deal with them in JavaScript.

Is it possible to use a MIDI message to send a continuous quarter frame after the full frame? For example:

Add some parameters in /mtc, like /mtc startTime duration fps;
Use a message /stopMtc to stop it.

Thanks for any help.

Open stage control doesn't provide clocking mechanism, there's no plan to support sending continuous mtc out of the box. You can schedule a periodic action using setInterval (in a script or a custom module) but note that o-s-c doesn't aim to be accurate and is not suited for timing-critical operations.
