So for the Swing FX, you have an option for Accent.
The docs:
https://beta.squarp.net/hapax/manual/modefx/#TGRXY8p

Amount of swing velocity accent. This parameter affect all notes.

So what is “swing velocity accent”? I understand what swing is on a track, it makes a delay of the trigger of the note. But what is swing velocity accent? What does it do the velocity of the note?

The pyramid docs around this FX have a better description:

Amount of swing accent. 50% (default) has no effect on notes volume. Decrease this parameter to accentuate the first note. Increase it to accentuate the second note.

Is the FX the same for this for Pyramid and Hapax? If so, what does “accentuate” mean?
