In terms of setting up Rewire, the later versions don’t require much work on the users part at all. In basic terms, the

system configures itself when you launch both ProTools and Reason. All that really leave for you to do is select the routing of audio and MIDI. I’m currently running ProTools 6.7LE and Reason 3, so the following guide is largely based on that setup.

Step one: Launch Pro Tools. In terms of Rewire, there is only one rule. Make sure you launch the master (or host) application first. When you go to close your programs, Pro Tools will warn you if you are trying to quit while Rewire (and Reason) is still running.

Step two: Launch Reason. Reason detects that ProTools is already running and loads itself up to run as a client (or slave). The Reason Hardware Interface module will indicate that Reason is running in Rewire slave mode.

Step three: Create Rewire inputs in Pro Tools. Inputs are accessed from RTAS plug-ins inserted in standard audio tracks or aux input tracks. If you are a on a budget like me, and only have LE, you should use aux input channels, whereas if your in the big leagues and are using TDM you’ll probably need to use record-armed audio tracks.

Step four: Connect something in Reason. When using Rewire it sometimes makes more sense to connect your Reason sound modules directly to the interface module so they are routed directly to individual channels in Pro Tools. Otherwise you'll end up with two mixers to deal with which isn’t ideal, and can end up coloring your sound more than you’d like.

There you go, that’s all there is to it. Now you can play and record using Reason as if it were just another instrument.
