Then I changed the name of the class to CutMask.<\/p>\n
In initClass<\/h4>\n
I changed the synthdef name to cutmaskchan
\nI changed the arguments to the SynthDef
\nI put in my own code for the fx = line. That’s where the magic happens!<\/p>\n
In new<\/h4>\n
I changed cutgroup.server.sendMsg to so it uses my synthdef name and my synthdef arguments<\/p>\n
In renderBlock<\/h4>\n
I changed block.msgs[i].add( to have my synthdef arguments
\nsince mine doesn’t change, I could skip sending anything, afaik<\/p>\n","protected":false},"excerpt":{"rendered":"
