Send CC's to ext gear: just to be sure

Hi, I’m setting up midi control for external fx units using the 10 CC encoders. The settings I set there don’t seem to be automatically sent, be it on pattern recall or sequence start. So I p-locked them on a trigless trig with a 1st condition so they are sent once when the pattern starts. Is that the correct way to handle this or should they be sent automatically at one point?

Thanks!
