No, that's just fine.  There is enough space for my fingers.  It's just
the act of trilling 3-4 on adjacent buttons in that direction requires a
dexterity that I haven't sufficiently developed.  I find it easier on
piano keys with their larger resilience and better ways to change the
relative finger position/distance due to the long piano key shape.  But
overall the payoff of the chromatic button system on a portable wind
keyboard is still a lot better.
