Long notes cut off early

General playback bug
Specific MS Basic Instruments

Bug description

When you have a long note (its just more visible for long notes) it will cut off the note early and not play the whole duration of the note. For a 31 measure long note at 120 bpm it cuts off about 6.5 beats early from what I've seen (about 5%)

Steps to reproduce

1. Make new score
2. Enter in a long note
3. Observe the note ending early

I think this is by design that the last 5% isn't played cause that helps to separate out notes with short note values and/or fast tempos. I think the tenuto mark brings it from that 95% to 100% if I remember right?

Even if it is by design, it shouldn't be a percentage, rather it should be a fixed note value so you don't run into problems with really long notes.

[MarcSabatella]

Indeed. The 95% was an experiment from long ago, implemented for piano and flute only originally, to simulate the effect of a slur (notes under a slur were not shortened. Percentage was used because that was the only way to represent that in the old instruments.xml that controlled articulations.

So I assume the current behavior is artifact of that, and definitely should be changed so that notes get full value by default. A shortening of the last note under a slur is reasonable, but as noted, it shouldn’t be a percentage.

This only seems to be an issue with specific MSBasic instruments.

I'm guessing theres more but I believe the organ and synthesizers instruments are the main culprits
