Reason's effects rack is now open to accept effect and instrument plug-ins from third parties--and already Softube, Korg, and several other companies have signed up. What's more, these will have all the characteristics of standard Reason modules, including back panel patch points. Reason 6.5, the next major update, will accept Rack Expansion modules and be available in the second quarter. Best of all, the update is free and while the third party modules aren't, you will be able to try them free for 30 days.
