Arpeggios, sort mode, and release

[eagles051387]

Hello, I'm on LMMS 0.4.14-rc1, and there is a problem with arpeggios.
This existed for a while, but I just did a bit more debugging. When the release of the instrument overlaps with the next note in sequence, a note will either a) fail to play, or b) play two notes together when the instrument is set to "sort" mode.

I can confirm this is still an issue. In sort mode, some notes get skipped - haven't seen the "two notes together" thing happening though.

This is still an issue (1.1.3 win64) - and I think it has gotten worse recently.

I've made a very simple example that shows it.

There are just two half notes in the piano roll and the arpeggio time setting is also set to half a note.

Playing this yields a lot of overlapping notes and strange clicking noise.

Worth noticing:

• Changing the tempo of the song changes the bug behaviour.
• Changing gate, range, sorting mode dosn't affect the bug.
• The bug only comes after the first looping (also it disappears from time to time in some strange pattern)

interesting! and tchanging the BMP, other weird things happens
when we get below 50 the 'double-note' is replaced by silence. The playhead moves over the note, but there is no sound.
I think that might be the case also at higher bmp, but there its not possible to discriminate the silence ?
fi:
at 60 bmp. arp: 2 octaves. TimeSync : ½-note
beat1 sound
beat2 silence
beat3 sound
beat4 silence
or..
1+ 2- 3+ 4-
second run is different:
1* 2- 3- 4+
where " * " is double note
3..8 as 2.
9.
1* 2- 3* 4+
That is reproduceable, and could(?) give insight in the off-sequence

How does current Master do in this respect?
Should this actually be marked at least Bug or isent it in fact Critical ?

[Umcaruje]

!? This bug isn't critical, neither its even milestoned, so it isn't such a high priority.

[musikBear]

@Umcaruje #2589 was marked critical, this is same thing, but its fine that its now marked 'bug'. :+1
Sort-mode may also be ok in current Master, because #2589 is closed.
Could you do a test of sort-mode on Master?

The later issue goes into more depth.
