Using the Transport and Tempo controls Basic Transport controls When you run ReWire, the transports in the two programs are completely linked. It doesn’t matter in which program you Play, Stop, Fast Forward or Rewind. Recording, however, is still completely separate in the two applications. When you run Reason as a ReWire Device, it’s not possible to record on audio tracks in Reason. Loop settings The Loop in Reason and the corresponding feature (Loop, Cycle etc.) in the host application are also linked. This means that you can move the start and end point for the Loop/Cycle or turn the Loop/Cycle on/off in either program, and this will be reflected in the other. Tempo settings As far as tempo goes, the host application is always the Master. This means that both program will run in the tempo set in the host application. However, if you are not using automated tempo changes in the host application, you can adjust the tempo on the transport in either program, and this will immediately be reflected in the other application. If you are using automated tempo changes in the host application, do not adjust the tempo on the Reason Transport Panel, since that tempo then doesn’t have any effect on playback! If you are using automated tempo changes in the host application, or change the Tempo in the host application, Reason will not use high-quality stretching of audio tracks! Ableton Link cannot be used when Reason is in ReWire mode!
