Potential bug with tubesynth

Not sure if this is a bug or if I'm doing something wrong. It seems that sometimes when I load the tubesynth program, Note Retrigger doesn't work. Instead the sound cuts out if you try to play another note (or the same note) too quickly. Before it's natural release? It doesn't go away by changing the preset. If I delete the track and add the tubesynth again, it usually fixes it. No effects or anything in the mixer that I can see. If I switch the poly setting to two or more voices, at least it doesn't cut out.

Maybe I am misunderstanding you but...

If you have the sound set to one note or monophonic mode, you’ve just described the behavior of a synthesizer that can only play one note. Hence, when you set it to two or more note polyphony it is able to let the first note play out.

NearTao, it's not that. The default poly setting for the tubesynth is 'Retrigger'. Under normal behavior, if you press a note, hold it down, then press a second note immediately after, the first note will cut out, the second note plays and the envelope retriggers. So, while there is only one voice, any key press immediately changes the voice and retriggers the envelope.

What I'm experiencing is that playing the same note, or a different note in rapid succession, will cause cause the sound to cut out completely. It seems that if the first note hasn't reached the sustain portion of the envelope (even if you've stopped playing it), any retrigger will cause the audio to cut out. Essentially if I try and play the same note over and over in rapid succession, maybe every 3rd or 4th time depending on how fast I'm pressing it, will a sound be played.

I've also encountered this,
Loading another synth and reloading back tubesynth solved it.
Only have encountered it once, though.
