the Patch Editor on the unit itself is something we believe kind of very hard to work with and prefer users to work w/Vsigfile. This used to be ok long time ago, with the 4000. I created hundreds of algorithms on it. In time the processing power AND the algorithms size have grown to "x" times…so the patch editor has become more and more less efficient in trying to work with. It's ok for simple editing, like adding a mixer or other simple things….
We are considering to add the old Programmer manual again on our website, with the necessary updates, just so that every aspect is covered.
But….anything related to how to create algorithms in the old Manual is covered and expanded in vsig Help File and Vsig manual.
The relay jack has no info because it's related to Vsig module C_RELAY, covered in the mentioned help files.
all the best
