Re: [Linuxsampler-devel] release trigger bug

[Garett S. <shu...@co...>]

I wouldn't think that single or multi release samples would make a 
difference. It seems as though the amplitude in ls is high regardless. 
I have Post Pristine and experience the problem with that. I get very 
unusual behavior with Post Pristine when I hold down the sustain pedal. 
The noteoff event triggers the noteon event sample when the sustain 
pedal is down.
