Zynsampler release crunching the sound

Hi guys,

just dipping my toes into zynsampler.
I primarly want to use it to record my jams, but when trying to play anything with midi i noticed the release value > 0 basically break the sound.
Sounds like bitcrushing.

I recorded just a few seconds playing an internal synth and then playing that back…

The on board samples seem to work though
