Yes,
I am also having this problem.  The weird modulating pulse sound appears on about 50% of the patches.  I am also working on an OSX machine. I am opening CS-80 as an HTDM in Protools.
My question is "Does this behavior appear in the actual program for Mac users"?  I want to buy this software tomorrow, but my desision will have to wait until I verify what this problem is...  Is there anyone from Arturia monitoring this forum?  Please let me know what this bug is and if its in the software package I want to buy...
