ZynAddSubFX Stuck Note in Dream of the Saw

Having trouble with LMMS? Ask about it here.
All right, so as the title suggests I am using ZynAddSubFX plugin playing "Dream of the Saw" in LMMS. Whenever one particular note is played (C#4), it will continue to play quietly long after the note has turned off. Stopping the music has no effect, only opening up the ZynAddSubFX GUI or clicking the panic button does the trick. I am running KXstudio, however the problem persisted even on LMMS windows.

I have temporarily worked around the issue by transposing Zyn down one half step, and then moved all the notes of the instrument up one half step, thus avoiding ever touching the C#4 key. I believe that the problem is somewhere in the piano roll then, as the issue does not persist when transposing like this. This probably belongs on the GitHub page, but I'll start with it here.

Good descission
Apologies if I didn't clarify enough. The preset this occurs with is "Dream of the Saw" It has not happened thus far with any other preset in ZynAddSubFx.

:P Nooo YOU explained perfectly, i just misread and thought you were playing some song, but the preset is named so LOL

You are correct! That preset is flawed.
The preset will hang in the way you describe, if any changes are made to its UI during playback

The preset is a so-call 'dual' I ti sbuild the same way as i explained years ago in this tutorial:
zynAddSubFX - Creating instrument-layers


I dont think it is 'our' bug, but rather one for the zasfx github team.
They have however completely stopped devellopment on the zasfx version we use in lmms, so im afraid i have to say, that this is a 'nothing to do' situation.
All righty. Well, like I said, I was able to work around the problem by moving all the notes up in LMMS and transposing down a semitone in Zyn. So if anyone else has their heart set on a specific key and using this preset, this is one way of working around it!
