I use both Sibelius and Finale and both programs have features that try to emulate a real person playing just like BIAB does with embellishment. Could they not improve on this feature by making say the melody do whatever the instrument that you choose play, be it guitar or piano of a Sax so that the chosen instrument would only have articulations that are meant for that instrument. Like a bend in a guitar or an overblow for a sax. Just wondering
