I don't know if you guys heard about this discussion, it's from last summer. I just ran across it now and remembered the issue with the sound on the Hive.

Anyway, they say that moving the sound to cog 1 instead of for example cog 5 makes a big difference.

Also the Stereo Duty object does the rest.

Cheers!
