Hi, I had just purchased DoggieBox recently when I upgraded to Panther. So I don't know if this is a general problem or something caused by the upgrade. But after creating a pattern using the "Ben's Premiere" drum kit and exporing it I always get clicks and pops... Mostly they are associated with the highest level points but some seem to be random, such as at the beginning. I don't hear the clicks when playing in DoggieBox, only when exporting. Also I have tried turning down the master output level, but it seems to have no effect on the exported result... Can anyone tell me what's up? I can post the pattern and sample result if that will help. Thanks, Pat Niemeyer Author of Learning Java, O'Reilly & Associates and the BeanShell scripting language.
