This is a question related to the rendering of midi signals. At times BiaB yields strange results when playing back its arrangements. Usually midi notes do sound during their midi duration. However, at times they do sound substantially longer. Why?

Here is how to reproduce this finding:
Load the demo song of Jazquint.sty. Set Guitar to solo such that you hear exclusively the guitar track; potentially reduce the tempo to s.th. like 60. Turn the chord Dm7 in the second bar to a shot. Press play and focus on the guitar notes of the Dm7 shot. Various synthies now yield different results. VSC DXi makes the guitar notes sound exactly during their midi duration here. Forte DXi and GS Wavetable, however, make these notes sound substantially longer - effectively botching a shot effect.

Now comes a related question.

With the style Jazquint.sty a typical guitar pattern are strums at each beat. Typically these strums are notated with respect to the respective midi durations -> long-short-long-short (long refers to durations of about 0:100, short is typically s.th. around 0:20). At times, though, some bars show up with midi durations short-short-short-short. At those bars the synthies create the following puzzling patterns -> Forte DXi: mostly long-short-long-short and sometimes even long-long-long-long, VSC DXi: long-short-long-short, Wavetable: long-short-long-short.

Why do different synthies create different renderings with respect to note durations?

Why do some synthies create long-short sounds with notes of durations short-short?
