|Product Version||OpenMPT 1.29.01.00 / libopenmpt 0.5.0 (current stable)|
|Summary||0001339: FM voice resets on ended volume envelope|
I guess this is a bug happening because of a workaround for hanging FM voices of some kind?

|Steps To Reproduce|
Let me know if you want the module I found this bug in. And if you want, maybe you can give some critique too on the tune as well if you have time :D
|Tags||No tags attached.|
|Has the bug occurred in previous versions?||Maybe back in another test version later than 1.29.00.57, but not futher|
|Tested code revision (in case you know it)|
Indeed, portamento between "stopped" notes should not possible, the IT compatibility setting "Do not apply any portamento if no previous note is playing" (enabled by default also in MPTM) takes care of that. Previously this compatibility setting did not affect OPL instruments (accidentally). Of course it's a bit unfortunate that this breaks existing OpenMPT 1.28 behaviour so I will see if anything can be done about that.
Oh okay so it isn't supposed to be like that. I tried to extend the envelope duration by increasing the last node by like 128 ticks, however the envelope doesn't reset. I thought that envelope-carry would have to been set for that to happen, or maybe I know less about Gxx than I think?
Envelope Carry is for notes without portamento. If you want envelopes to retrigger with portamento notes, you have to enable "Compatible Gxx" in the Song Properties dialog.
Something I found out right now in asikwp_and_wito_-_midday.mptm at pattern 22 (https://modarchive.org/index.php?request=view_by_moduleid&query=187116), that might be related to this, is that the Qxx seems to be affected too since it wont retrigger any FM samples.
