Piano Roll: not all notes are played, if one goes right after another.

[vlad0337187]

Hello.

Problem.
Notes, that go just right after the same one aren't played by Piano Roll. They aren't intersected, I checked on 800 % of zoom.

Here are notes:

Same notes under zoom 800% (they doesn't intersect):

I think this issue is two-fold: piano-roll display issue and note on/off issue. Display issue is already reported in #3919.
By the way, which instrument is problematic? I guess you mean a note does not play its sound. Is it SF2 player, ZynAddSubFX, or other instrument?

@vlad1777d can you upload project?

[vlad0337187]

@PhysSong , I use SF2 player.

[vlad0337187]

@musikBear , of course I can, but it's at home (I'll be there after 2 hours).
Also that project is really big, so I'll try to cut only "problem" place and create new project with only one instrument and pattern.

@musikBear , here is example with bug in Piano Roll: bug___lmms_piano_roll.mmpz.zip

Just tested. The second C5 note plays sound, but it's not displayed. I think this is a duplicate of #3919.

[vlad0337187]

Yeah, it is.
Sorry, I searched by "note", "note not", "note not played", but didn't found that =)

Closing as duplicate of #3919.
