Changing sound parameters from external controller while previewing sounds

I was under the initial impression, that it is possible to live tweak sound parameters from sound browser without committing the sounds to a track.

I don’t know if I changed something, but right now, the parameter adjustments stay active only while a key is pressed and once I play the next note, the sound preview resets to the stored sound settings.

How does it work for you? Is it possible to adjust sound parameters from external controller while previewing the sounds or does the sound has to be committed to a track for it to work properly?
