There is a bug in Maschine Central, I just tested in Maschine+ standalone, but the thing is that the highest velocity in the multisampled instruments only go up to 126, so if you play hard it doesn't sound, and is much more frequent than I though when I hit the maximum velocity while playing and it just drop notes.
it is an easy fix, but is hard for us to fix it as it would require to go through all notes and extend the highest velocity note up to 127…
Edit: Now I see that not all multisampled instruments have that problem, but there are a lot, check for example the guitars many of the first ones that appear hathe problem.
