@rorywalsh :Hello Rory,
Sorry for keeping you busy . Thereafter a feature I find strange whilst working with Cabb2 Beta. ( but it is not a problem per se)
Create a patch. Save it and give it a name (CTRL +S).> The patch is saved.
Now quit Cabbage. without changing anything. Then cabbage ask to save the patch under new name. Why ?
EDIT : I see that it proposes to save Cabbage Patch (but what is the difference with Csound file)
Hope this helps,
