hi edward,

thanks for the quick reply, most appreciated....

well, i don't know about interconnectivity, but i got the same error when i loaded a project into 6. checked and there's no 'sony' listed plugins under sony (audio), just a collection of fx's (which show they're sony when opened)? since i can use these in projects in both - well what the hell?

still wondering though....

thanks

leslie
