Just a heads up: Digidesign have now released a new version of Pro-Tools LE (5.2.1) that allows collaboration via Rocket Network . I gotta say, being a Digi 001 user I've been waiting on this one for ages - tried it out last night and works like an absolute dream!! The 5.2.1 download is free if you are a registered 5.1 or 5.1.1 user. To download just click on link at Digidesign Site Basically you then are able to log into DigiStudio and collaborate globally. I'm pretty sure you can check it out for free, but there is a monthly fee if you want the full kahuna. Would love your reactions to using it - I know it has blown me away.
