That's true...
Even though its not the same Sampler you might be correct. As far as I know there is an AllNotesOff event, when changing Samplers Bypass.
But I already tried a different order, it did not make a difference.
I think I also tried delaying the PlayNote once, but did not work as well and lately I tried a different sample and it played, so it seems to be a quite specific issue.
I'll try to rebounce the sample I'm using, maybe that fixes things.
