ReWire in Cubase

ReWire allows you to stream upto 64 audio channels and
ReWire2 supports upto 256 channels. ReWire helps in sharing the resources
between the applications, especially to share the audio card and control the
outputs of each channel via the card. 

It also synchronizes the Transport of
both the DAWs so that you need to only control the Transport in Cubase and it
will automatically be mirrored in the ReWired application, such as Pro Tools, FL
, Reason, Studio One.

You also have the option to separately mix the channels
according to your need. ReWire2 allows you to send the MIDI tracks from Cubase
to the supported applications, creating a harmony between the various
applications. You can choose different VSTs in the other application and play that
VST through the MID channel in Cubase.

These methods help you to reduce the load on your system and
helps you to run the session in a smoother way, rather than loading the audio
applications in a separate process.

Basic Procedure

The main thing that you have to do before you ReWire is the
launching order. Since Cubase is the master in this case, open
Cubase first and then the secondary DAW.

While quitting, this process has to be reversed, first quit
the secondary DAW and then quit Cubase.

Once Cubase is opened, if you open any other DAW that
supports ReWire, it will automatically get routed to Cubase. In case, if you
want to load the secondary DAW without Cubase ReWiring it, you will have to
open the secondary DAW first and then open Cubase

Be aware that if you do
this, both the applications will be using the audio card and can create a huge
load on your system.

Starting ReWire

All the applications that support ReWire will be listed in
the Devices menu in a separate group. Select the
required application from the list. A panel consisting of the available
channels for that application are visible.

Here, select and activate the various channels that
are supported in the application by clicking on the power button besides the
channel. If the application supports stereo channels, they’ll be available as
a paired group and you need only to switch on one; the other channel will be switched on automatically.

If only mono channels are available, switch on each channel individually according to need. Bear in
mind that as you activate more channels, the load on the CPU increases.

To make things easier to understand, rename the
channels to how you’ve routed in the application. It’s always a good idea to
rename tracks depending on what each channel sends. 

It helps to easily
understand what each channel represents in the Mixer window. The default names
may not prove very useful in such a situation.

Configuring the ReWire Application

One of the important features in ReWire is the synced
Transports. Control the playback for both Cubase and the ReWired
application via the Transport in Cubase. The supported Transport controls in
the ReWired application will be mirrored in Cubase and you can control the
settings via Cubase

If you press the Play
button inside the ReWired application, it will be automatically reflected in
Cubase as well. Recording is not, however, linked together so that you can
control the recording option separately.

If you have set a loop region in the other program, this
is automatically reflected in Cubase.

This way, you can have the
application play a loop repeatedly and Cubase will play the same region
in sync with the application. This is great for testing separate VSTs or
Instruments in both the applications at the same time. 

For example, play a
drum loop in one program and test the tone of a synthesizer in another in sync
with the drum loop.

Setting the tempo in Cubase will automatically be affected
in the application as well. If you change the tempo in the application, it will
also be automatically adjusted in Cubase

If, however, you have a Tempo track in
Cubase and if you adjust the speed in the ReWired application, the Tempo track
in Cubase will be disabled and Cubase will follow the tempo set in the

When using MIDI via a ReWire2 supported application, the
MIDI channel outputs in the application will be available as MIDI outputs for
MIDI tracks in Cubase. With this method you can play MIDI tracks in Cubase
through the MIDI channels in the ReWired application.

Sample Rate

While settings the Sample Rate of a project, make sure that
the ReWire application also supports the same rate. Some applications or
synthesizers may support only a limited Sample Rate and if Cubase is not set to
that sample rate, the pitch of the sound from the application may sound lower
or higher than the original pitch. 

If this issue occurs, set the sample rate of
Cubase to the one supported in the ReWired application or synthesizer.


ReWire is a very useful protocol that can help you to
control another application inside Cubase with the full capabilities of both
the applications. All the channels that are routed via ReWire can be treated
like a normal channel in Cubase

You have the option to add EQ, Inserts, Sends
or route to other busses as well. Automation can also be written on these
channels just as you would do for a normal track in Cubase. You also have the
option to export these tracks as a single audio track or multi-tracks according
to your need.
