On none of the percussion instruments in the screenshot are the correct instruments sounding. I use middle c (C3) to insert notes, non of the other keys work so I assume that is correct. But there is no sound or the wrong sound. Mostly a bass drum. What am I doing wrong here? I am using NotePerformer and working in Galley view.
Hello, I too am having problems with mark tree it plays a loud pedal tone. Is there a way to edit procussion midi notes sent? (I can’t find anywhere a page with midi note data) or a way to see what note it is actually playing.? Does Dorico Percussion stick to GM Midi Standard? It seems to be a keycap expression issue.
I added instrument for MARK TREE and added a whole not on line. It played some loud -c1 etc note. So i realized it is maybe a problem with me? loading halon sonic se with wrong expression maps? not sure. Anyone else entered procession parts? I know when i print them and go to recording date at TV show they will p[lay it as written perfect. It would be nice for Dorico to play it back correctly though.
I feel your frustration. People here are awesome and they will fix us up.
Kind Regards

PS just notate it correctly and the players will play it down perfect!!!
Not sure what is happening, but after having switched between Noteperformer and Halion a couple of times, and moving the percussion instruments in and out of a kit, they suddenly are sounding. Although sometimes they still give the wrong sound. Feels a little unstable.
I am actually able to get the sounds I want, but I have to find the correct sound first on my midi keyboard, playing it will notate it as well and playing back correctly. So I will have to keep a list next to me to know which midi key contains the correct sound. I thought that every percussion instrument would being triggered by middle C, but that is not the case.
I certainly did not… 
Will do it now, thanks PianoLeo
I see that this is for percussion kits, which is not the same as a normal single player percussionist. I played around with it, but this isn’t affecting anything when you don’t use percussion kits.
Andre, what I gleaned from the manual is that, regardless of whether you’re using single line instruments or percussion kits, the option “Use staff position” may yield a different result to the option “Use percussion map”. Go to Edit > Preferences > General, scroll down to Percussion Input. Next to “Input onto single-line staves” you’ll find these options. Which is currently selected?
Staff position, and I assigned the C3 which gave midi key number 60:
