Apologies for the error in my last post.. I have edited to reflect what I now know:
So just for the record: The QC patches that I downloaded from Matthew Haber's site automatically select the most recent Syphon server, but the CeGe examples allow the Server Name and App Name to be specified. NI_mate V1.1 outputs Garbage to Syphon on a stream along side the "Ghost" and other image streams. When using Matthew Haber's Syphon Client with NI_mate V1.1, you will only see the garbage stream from NI_mate because it is the last in the list. The CeGe Extras folder contained the solution for me because of the published inputs "Server Name" and App Name". In Isadora, the CeGe "Syphon Client.qtz" actor can be hard-coded using these inputs Server Name = "Delicode Server" App Name = ."Delicode_NI_mate". The CeGe examples are part of the Quartz composer plugin download from the Syphon website!
The CeGe examples are .qtz files so they have to go in the User/Library/compositions folder or one of the other folders that you have pointed Isadroa to. They should not go in the FreeFrame folder because they have nothing to do with FreeFrame.
