Hello
I have a problem with pvsti instruments played with Polac vsti.
Image
The second G-4 is not played because the first "off" of the G-4 is not played yet.
It's the same with implicit (another note starting) or explicit "off".

I can correct manually the problem if I shift slightly the "off".
But it's very difficult to find every place where the problem occurs.

So, any idea ? Some hidden parameter somewhere :-)
Thanks !

Hi, it's possibly vstdependant, here it seems to work correctly with some vsts.

The first g-4 note off should be processed before the second g-4 note as it is sent on sampleframe 0 in block whereas the second g-4 is sent on sampleframe 1 in the block. I'm doing a stable sort on the events later on so they should be in right order. It could be problematic If I would send both g-4 and note off on sampleframe 0, in this case the note off is processed right behind the second g-4 and cuts the note.

However there are vsts that do not position their midi events sample-exact, mostly older vsts I suppose, they ignore the sampleframe positioning completely, this could cause some problems.

Thanks Polac.
I use ARIA player VST (with Garritan Personal Orchestra sounds).
This player has a good reputation.

I import a midi file in buzz (with the pianoroll), switch to Pattern XP, then play it.
Playing the same midi file with the same ARIA player using another midi player (Reaper ...), works correctly.
But I suppose there is no reason that this is not the case.

Would you have the possibility to try with ARIA player ?
