I understand that creating a virtual input port would have to be done dynamically, hopefully something simple like: [self addInputPortWithType:QCPortTypeVirtual forKey:@"inputVirtual" withAttributes:NULL]; The problem is that this string constant for virtual port type is unknown would have to be exposed by Apple. Without that string provided by Apple you can try and guess what it might be. NSLog() shows all type constants are the strings exactly as their constant names, ie: NSString *QCPortTypeString = @"QCPortTypeString"; I tried some educated guesses like @"QCPortTypeVirtual", @"QCPortTypeId", @"QCPortTypeUntyped" but it did not work.
