ReWire
Logic supports the ReWire software interface from Propellerheads, a software
manufacturer. ReWire is an interface between sequencer and audio applications.
ReWire works with hardware supported by Logic’s native audio engine (see “The Audio
Hardware and Drivers Dialog” on page 377).
Please start Logic first, and then start your ReWire application(s). ReWire scans for
ReWire-compatible applications or system extensions; Propellerheads’ Reason, for
example.
Logic will display the audio returns of ReWire-connected applications as Audio
Objects: You’re able to insert plug-ins and create sends to busses on these returns, as
per a normal audio track.
In order to use the audio returns of ReWire-connected applications, select an Audio
Object and choose the desired ReWire audio-return in the Channel pull-down menu of
the Audio Object. You will find ReWire channels listed by name, along with the audio
tracks, inputs, busses, and outputs in this menu. ReWire (or the application that the
connection belongs to) generates the names for these channels. The name of a ReWire
channel is irrelevant to Logic.
As an example, if a channel is called “Mix”, it has no specific function related to that
name as far as Logic is concerned. It’s up to you to decide what to do with whatever
channel. If there is no Audio Object for a ReWire return created in the Environment, no
audio is transferred between a ReWired application and Logic. How does this work in
practice with ReBirth, for example? In this scenario, you will find two channels called
“Mix L” and “Mix R” within Logic. The two Mix channels return the summed mix of
ReBirth’s outputs. You will also find channels for every individual instrument. When
creating an Audio Object for another channel such as the bass drum, for example, you
will only hear the bass drum through that channel, and it is removed from the mix
returns.
Logic is always Synchronization master. As Logic is also the Cycle master, Skip Cycle
works, too.
The following functions are shared between the applications:
• start/stop,
• repositioning,
• cycle start and end,
• tempo change
