FLStudio but since the dreadful release of Windows 8, after being an exclusive Windows user, I now try to do as much on OS X as possible so I can't wait for a native OS X version to be released ...
FLStudio 20, but I don't have Diagnostics under the help bar. Do I have to purchase this separately or is flstudio 20 supposed to come with it? If it is, I don't have it, which is weird ...
