I just imported the MIDI from a composition of mine done on Sibelius. I was applying different VST to each track but curiously when I got on the brass tracks, even if sounds come out when I play the routed VST instrument, when I press play no sounds come out ! ^^
Made a little video to illustrate the issue : - YouTube
Use ‘List Editor’ on the track that will not sound and make sure the
MIDI note info on those events are set to the same MIDI channel as the VSTi instrument.
