Hi, I'd like to know if other users of Mo'Phatt (Proteus 2000 series) have experienced these problems. 1. Only 17 filter types can be selected out of 50. 2. Some note on messages are ignored (some keys don't make sounds). I'm also writing a Morpheus editor, as it crashes my Mac, when filter type parameter is edited. Thanks in advance for any tips.
