Thanks very much for your reply. Articulations would be MUCH better for what I'm doing becuase I want the technique only on selected notes. I'll include a screenshot of a representative place. The only trouble is that these staccato articulations still play back like a single note because of the soft attack of the GPO solo KS violin. I would be really happy if I could make this sound right.
I know I could edit the definition for the staccato marks to make them play shorter, but that would not change the attack so I still wouldn't hear them. This is a fairly important issue. I'm doing quite a bit of arranging and I really need to be able to play a decent sample file for those who approve the arrangements--I need it for professional purposes, though not a final product (like a film score).
Also, related to the HP playback action "KS=D2, Mod" that you commented on. What is the "Mod" part.
Any advice or help you could give me would be greatly appreciated, to say the least!
