flashserver - communication between Max/MSP and Flash The flashserver external for Max/MSP allows for bidirectional communication between Max/MSP 4.5 or later and Macromedia Flash 5.0 or later. falshserver was written by Olaf Matthes. Have a look at a screenshot to get an impression how it looks like. As I'm currently working on flashserver version 2.0 I will not fix any bugs in version 1.1
