Hi there,
I have been playing with the demo of Circle in Logic 8.02 on OS X 10.4.11. Sometimes the audio output of Circle freezes as if it is repeating a very short buffer. The sound changes with different patches but it is as if all output is in a very short loop. This output is also very loud (I have to turn down the logic fader 30 dB to make it stop distorting, although the sound is still very unpleasant!). I am very tempted to buy but this bug is putting me off. Opening a new instance of Circle or refreshing the Logic audio drivers do not help.
