Notes disappears randomly

[herodotas]

Hi,
I found that I play some sequences with VST instruments, sometimes one or few notes disappears randomly, not from piano roll , but dont sound when played , or are played in portamento mode, which not selected or programmed. Don't know about native instruments, because don't use them. Win 7 x64 LMMS 1.2.1 but this happened in 1.20 to.

Ok, so you got a VST that fails randomly.
If it was predictable with certain specific notes not playing, it could be the register spread of the VST, but now its random and then its a VST issue.
Iow. Your VST fails in the 5point-test :
Replays notes reliable and predictable
What is the name of the VST?

I dont think, this is VST fail, because, this happens with no one VST and randomly.

That is really not an impressive VST. You get the same and more from zasfx default presets1 -Not to mention Synth1, that is seriously better, leaner, and have mio of presets online.
-However, i could not recreate any drop-out notes. All notes plays as expected in all registers.
I need to see your actual score, and know witch patch you have these drop-out-notes.
But my std test did not show any issues with dropped notes.

What is impressive VST? Guitar and piano impressive or not? They are, like PG-8X, just instruments.
IMO zynaddsubfx have very bad filters, hard to work GUI, and only few automatable parameters. I have Synth1 in my folder very long ago, so know him very well and using presets are not my workflow. I dont ask to change one vst to another, I just report LMMS problem and search ways to resolve. I wonder any users has similar problems and developers know that?
I cant recreate this every time, so why I wrote randomly, and are others plugins with same problem, I cant remember, because LMMS not my main DAW, I just like play with it sometimes, and rare save projects, but who know future?
So your answer is not constructive at all, it is not solution.
