--- Comment #3 from Tony Austin gigaday@googlemail.com 2011-10-13 08:12:14 CDT --- Bruno: I think that Windows is treating the .zip files as folders, which is something it does. There are lots of other files in the folder where it lists the *.m1progs which are not being shown.
The official download link is at http://www.korguser.net/shop/software/, but you have to buy it (50USD). Either I can do the testing or I can upload a copy of the program somewhere for testing.
