This could be a bug, but I find when using random position in the midi modifer, to give a little humanize feel to the track, it does not affect the expression map entries. So you end up with missed articulations. Shouldn’t the random position move the expression map data as well to ensure it is all in sync?
Unless there is a preference setting somewhere I have missed, this means until it is fixed, random position cannot be used with expression maps, though I think positive values are probably OK, it is the negative value that takes the note back before the articulation change.
Has anyone else noticed this, or now realize this is the problem to missed articulation changes?
