Hydrogen and beatbuddy

I’ve seen posts recommending hydrogen as a good midi editor to make beats for the beatbuddy. When I export midi files and open them in the bb manager, they cut off at weird lengths. Sometimes they cut off a bit short, and other times they play a whole bar of silence before looping. There must be something simple I’m missing, so anyone familiar please help.

Yes, I wrote about it all over the place.
TLDR: Don’t start your MIDI pattern with pause ever! Use any unsupported note like MIDI note 0.

Here are some links where this was discussed:
