I am running Sib 7.1.3 and using the S7S Soundset 7.1 template. On some sounds (ie. trumpet) if I add an articulation (accent, stacc etc), then the sound is silent both on playback as well as scroll through while working on a piece. Non-articulated notes speak fine. This may be a sibelius forum ?, but Hugh has been WAY more helpful in the past than wading through the myriad of info on that forum trying to find answers.
Thanks,
Derek
