Never ending reverberation

Having trouble with LMMS? Ask about it here.
I copied the small bass riff and have a never ending bass reverberation in my sound. Does anyone know how to abandon that?

I append the project file and the sound. One can hear it especially at the end. The reverberation is overlaying everything and is everlasting. Thanks for any hint!

I'm not sure but you may have to pack the files as .zip to append them to the forum.
I uploaded the ZIP to my own server:

I updated from LMMS 1.0.3 to 1.1.3 and it helped a little. Is there a mis-setting in the ZynAddSubFX?

Something like that yeah. I think it's this bug and it'll be fixed soon.

I didn't hear the stuck tones in your file but have experienced it too.
oh yes, not an 'never ending reverb' but a hanging note.
This can occur in a couple of different ways
* if you have the zasfz GUI opend during playback and in the zasfx KB make a key-change exactly as a note event starts
* if you fiddle with arpeggio settings during playback
...and perhaps some others ..
But to get RID of it:
Listen and find the note
Press that note on the LMMS preset keyboard with your mouse
That should release the hang-note
