Br: Missed Notes For Vst And Dssi Udner Linux

Hi there,

A couple of weeks ago I noticed that Hexter DSSI misses some notes (for some presets a lot actually!) when playing a pattern or even when hitting the keyboard. Since Hexter has other problems, I thought it was the plugin itself.
However, today I tried TAL NoiseMaker and the same happens. It is quite extreme for preset 54: Big Synth FN! What is going on here?
