NI Midi recorded tracks cut out after exporting

Hello,

Hoping someone can help me with this.

When i record a midi track, for example a piano, it will play back in my Logic Pro X project fine but when i export/bounce the project or even the track by itself the audio will cut out shortly after the note plays despite it being a chord being held for the length of a bar. This will happen sporadicly through out the export, there doesn't appear to be any distinct pattern other than it only happens on tracks i use Native Instrument plug-ins on. i have exported two tracks (1 NI and 1 logic own plugins and it was only the NI plugin affected).

I moved all my NI sound libraries to an external drive as it recommends but the problem is still there. Ive varied the setting in my logic project as well including export settings but the problem continues, leading me to believe it has something to do with my NI plugins.

I would be more than happy to provide an audio file if it could be of help.

Really need this fixed as i can't export anything making it all rather pointless.

Thanks
