TWS Edit: removed .sib Template file.
Has anyone found any resolution to this issue? I have the exact same thing happening. In full band scores using the template, some low brass parts (baritone, tuba specifically), the piano and, weirdly enough, some articulations in the Mellophone part won't playback. The Mixer is getting the signal but no sound. It happens when I create a new score using the template or open old scores where all the parts used to play back perfectly. To my knowledge, nothing is different about my set-up from when I opened the same scores last marching band season and everything worked. I have attached the score I am getting started on. I haven't really begun writing percussion, just plunked in some chords here and there to test sounds.
Any information would be very helpful.
