I am writing a percussion ensemble piece and I'm having issues getting the correct sounds to playback for certain instruments. I can't get the concert snare to playback the snares off sounds. I can't get any of the suspended cymbal rolls to playback at all. I press the keys on my midi controller and it doesn't make any sounds for those specific samples.

but when I go into kontakt 5 and test the samples through the keyboard in the program they all playback as they should.

I'm using Sibelius 7.5 with VDL 2.5.5
Windows 8.1
Sibelius VDL template 7.0a

Thanks

Please attach a screen shot of your Playback Configuration.
