Operation Manual

REWIRE
325
ReWire and the Reason Engine are common resources to the two programs (the other application and Reason) that
generate the audio and passes it onto the other audio application.
Terminology
In this text we refer to Reason as a ReWire slave and the application receiving audio from Reason (this could be
Steinberg Cubase, Apple Logic Audio or MOTU Digital Performer, for example) as the host application.
About system requirements
To run Reason together with another audio application of course raises the demands on computing power. However,
adding ReWire to the equation does not in itself require a more powerful computer. On the contrary, it is likely that
ReWiring two programs requires less power than, for example, running them with one audio card each.
Still, you should be aware that running two powerful audio applications on one computer will require a fast processor
and most of all a healthy amount of RAM.
About synchronization
All synchronization to other equipment is handled from the host application - not in Reason. In fact there are no spe-
cial synchronization issues. All that is said in the host application’s documentation about synchronizing audio chan-
nels is true for ReWire channels as well.
For information about MIDI Clock synchronization - without using ReWire - refer to “Synchronization to MIDI Clock”.
Launching and quitting applications
When using ReWire, the launch and quit order is very important:
Launching for normal use with ReWire
1. First launch the host application.
2. Then launch Reason.
Quitting a ReWire session
When you are finished, you also need to quit the applications in a special order:
1. First quit Reason.
2. Then quit the host application.
Launching the host application for use without Reason/ReWire
If you don’t plan to run Reason, just launch the host application as usual. We recommend that you then also deacti-
vate all ReWire channels if required (see the relevant section for your program, below). But this is not completely crit-
ical; ReWire does not use up very much processing power when it isn’t used.
Launching Reason for use without the host application
If you want to use Reason as is, without ReWire, just launch it as you normally do.
