Kontakt 8 unstable in FL Studio

There was an error rendering this rich post.

Hi everyone,

I have a recurring problem with Kontakt 8 in FL Studio:
Each time I use multiple instances of Kontakt (one per FL pattern), at some point the plugin will become unstable. For instance, it will either stop functioning on random tracks (no sound), the volume fades until I barely hear the sound, or the Tools (Chords, Patterns, Phrases) will start dysfunctioning.
I need to reload my project multiple time until Kontakt fully works again, when it actually decides to :)

So my question is: is there a specific MIDI or Audio configuration that I don't know on FL, to make Kontakt work properly ?

Thanks for your time !

It will behave normally on an empty project. I think it's a question of RAM in my case.

I did some researches, and what I found out is that you need to optimize the audio settings, like increasing the buffer size from the audio card. Also reducing the timebase (PPQ), and purging in Kontakt regularly, seems to help using the RAM more efficiently.

Hey there, please give this a try: My Kontakt Instrument Is Out of Sync in FL Studio It has helped users with similar issues.

Hey ! Thank you for your help.

The good people at Sine told me to do the same with size buffer, but for another problem, and it actually worked.
I've just tried this method on a project that has multiple Kontakt instruments playing together, and it's a mild success. I still have one piano using the Chords Tool that doesn't want to play. And as you can see in the screencap, 3 circles have disappeared for no reason.

Can you check if it's the same if you open the same tool & instrument in an empty project? What is the MIDI channel for the Piano in Kontakt?

Also - what preset did you have loaded in the Chords tool?
