Noisemaker and Logic Pro 9.1.3 Problem with CPU Load

[benmuetsch]

Hi all,

atm I am using this pretty awesome synth. But there is a problem which is really annoying. When i turn knobs and sliders in the GUI my cpu load goes up to 100% and there are cracks and popping noises. Sometimes i even get a system overload. However, thats only while opening the cutoff for example (or any other knob). If the gui is closed its all fine.

My computer is a 2008 Macbook Pro with 2,53 ghz Core2Duo, so thats not the problem.

Thanks!
