In LV2, MIDI is sent as raw MIDI bytes inside an Event, and an Event is a part of a Sequence. Everything is flat buffers, so you can achieve this however you like. You can see an example of doing it more or less manually in Jalv:
https://gitlab.com/drobilla/jalv/-/blob/master/src/lv2_evbuf.c#L154
You can also use the forge.h utility header, which makes writing complex atom buffers simpler (although is arguably overkill for just MIDI), see an example here in stepseq.lv2:
