Crackles while rendering when a Kontakt 5 instrument is introduced


just finished a song, but now there is a crackle in the rendered wav at exactly the point when a Kontakt 5 Instrument starts to play. Its an e-guitar from the Factory Selection. I tried different settings for the Compatibility Options but the crackle is still there. Any idea what to try next?

Further data:

Rendered both realtime and offline

CPU load is at 30…45%

Soundcard: Edirol UA-101

OS: Win 7

Renoise V3.1.0

Kontakt is upgraded to latest version.

Thanks for help!



Workaround: Do a pre-pattern before the song, play all instruments once. After rendering cut the pre pattern part off. By this no crackles after rendering.
