Thanks alot!
That helps me out :)

Hey,
i want to use multiple samplers and set their volumes through knobs.
It tried it like this

inline function onVolumeSliderControl(component, value)
{
   reg x = Synth.getSampler("Top");
   x.setAttribute(0,!value);
   reg x = Synth.getSampler("Bottom");
   x.setAttribute(0,!value);
   reg x = Synth.getSampler("Room");
   x.setAttribute(0,!value);
};

Content.getComponent("VolumeSlider").setControlCallback(onVolumeSliderControl);

but the result is weird and seems not to work.

any idia?
