Hi Paul - wow I’m honored - I caused a ‘matter for the boss’
yes I have to confess, that I was ‘crying on the wrong party’ … I spent the whole night to brake this down - as it looks like that no one else might have this problem …
It turned out that the real problem here was a SpeedumLite 0.92 Plugin which caused this Segemetation Fault … It works fine with all other plugins but when it comes together with helm this causes this problem → and then, the problem stays consistent ! as long as Ardour will not be restarted → so just deleting the Speedrum Plugin or deleting the channel where it was loaded into before, does not help ! - some memory might stay damaged from this Plugin…
I can replicate this problem in Tracktion → Tracktion crashes as well in this constellation.
But there I never stumbled over it, because Tracktion has a own Drum Sampler , which I used during testing Tracktion - and I don’t use Tracktion by itself very often - only their Content Plugins.
So it became clear that it’s the SpeedrumLite 0.9.2. Plugin - not helm and thanks god → not Ardour !
I am very sorry for the inconvenience and turbulences I caused here.
