Newb Question - So far, my process with AD2 is to find a beat and drop it into my MIDI track, but I have to tediously link them together one by one, which is a kind of psychological root canal after a verse and a chorus. Is there a way to drop that 2 measure pattern into the MIDI channel and then just repeatedly extend it outward via copy/paste, drag, or some other functionality? I've searched for documentation/ videos, tutorials, etc., but to no avail. Thank you.

CTRL+L converts a MIDI clip to a groove clip. Then click+drag the end of the clip.

You can also use the Pattern Tool (Press F9 or see the HUD or Control Bar.)

Thanks to  both of you! Got me there. What does the HUD acronym stand for?
