OPZ Synth engines length

Hello, I have a question about external sounds on the OPZ. If I load a sound that I created myself into the OPZ , it is only 6s long. Is there a setting in the OPZ that the sound does not stop after 6s when the keyboard is pressed? Thanks in advance

Push and hold shift while playing a note on the keyboard, release the note and keep holding shift, release shift. And. VoilĂ 
Or change the looppoints for the sounds or change the release time on the envelope or put some reverb behind it.

Thanks, i will try it!
