@unfa can you give us some branch information about this bug? I assume you're on stable-1.1
?

I'm expiriencing this with version 1.1.1 from KX Studio repos. Exact version: 1:1.1.1.1-1kxstudio-3
I can confirm this on both 1.0~ and 1.1.3 I've seen it many times but didn't knew how to reproduce it. This is true in both song editor and bbTrack. The difference between the two is that 1.1.3 also crash if I try to delete the hung track while 1.0 lets me continue working after deleting the track.
OK. I bisected the code to try and find why the bug change in quality from hanging with a cool drone to crashing when removing ZynAddSubFx(while playing said cool drone).

That commit is a... "...messages on splash screen when loading"?! Beats me. I went and removed that commit from the latest build and it went back to just failing with a cool drone that could be removed by deleting ZynAddSubFX. I don't think I've ever seen this bug with another synth but ZynAddSubFX even though I've tried to provoke it.

@zonkmachine That commit introduced the errors in #2049. It's because the LMMS' Engine class now implements virtual methods, and that causes a conflict with ZynAddSubFX's Engine class since their vtables get muddled up. It looks like it'll at least be fixed once our Zyn version is updated to 2.5, if not sooner.
Nice job with the bisect. I'll have to learn how to use that tool. Note that that particular commit was introduced after 1.1.3, however.
Nice job with the bisect.
Well thanks, I think I've found a hobby within the hobby. Next step is to script the bisect sessions. That will be glorious!

Correct, I was on master~ish.
But none of this explains the original problem (OP) then does it?
Is there a chance this is a duplicate of #340? Zyn has its own envelope, so this bug may be more benign on the native instrument plugins.
I can't replicate this any longer.
ZynAddSubFX seems to produce a never-ending note when combined with LMMS's arpeggiator.
