I am using NI Kontakt 5 sampler editor. And when I try to delete some unnecessary sounds, the program starts to act like it's working on the removal, but nothing happens.

This happens only with large files .wav above 30 MB When editing small sound files everything works fine.

What can be wrong?

  • Do a low-quality bank, produce the music than create an analog high-q bank for rendering. Useful!

When using the Kontakt 5 in a trial or demo mode, there may be a limit on the size of files it will read. Check the link here, and investigate your setup, you may still be able to play the the larger files. There is mention of getting an additional activation Serial Number to use.


Hope this is of some help to you. ~catz


Well if you treat your original source recordings having unnecessary bits, then tough tetris.

Have you tried cropping first, and then getting rid of unnecessary bits?
