Control Room replaces Audition bus

You have updated from Cubase SX 3 to Cubase 4 or higher and you miss the Audition Bus?

Well, that one is no longer part of Cubase 4. Its functionality has been entirely replaced by the Control Room, which offers much more possibilities by the way.

At first please note that the Control Room in Cubase 4 has to be explicitly enabled by you. As long as this is not the case, audio preview functions are routed to the Main Mix bus set in the Output Bus section of the VST Connections window. A disabled Control Room does not allow to monitor the output of a real time export. This only works with an active Control Room!   

This article will show you the easiest way to setup a replacement for the Cubase SX 3 Audition Bus using the Control Room in Cubase 4.

Before you start please make sure that the driver of your used ASIO hardware is selected and ready to operate.

Now do the following settings:

  • Go to menu "Devices"
  • Select "VST Connections"
  • Select the tab "Studio"
  • Click on the greenish (PC) / grey (Mac) highlighted button "Disable Control Room" to enable the Control Room. The bus "Monitor 1" is automatically added to the bus list
  • Click on the "+" sign of "Monitor 1"
  • In the column "Device Port" select the matching device ports of your used ASIO hardware to which your monitoring system is connected.

As you have probably noticed, the list for selecting a device port shows you that other busses are also using the device ports used for the "Monitor 1". In this example it is the "Stereo Out" output bus as displayed in squared brackets.

For the next step please make these changes:

  • Change to the tab "Outputs" in the VST Connections window
  • In this example it only exists one output bus which has been used as the monitoring bus when the Control Room was disabled, but we now have added a Monitor in the Control Room. Therefore, please set the device ports of this output bus to "Not Connected".
  • You may have noticed the red loudspeaker symbol on the left of the bus name. It means that his bus is set as the "Main Mix" bus. For details about this please consult the Cubaser 4 Operation Manual

Attention: If you do not make these changes to the Main Mix bus you will hear audio signals from both busses at the same time with increased volume, also distortion can occur. As a rule of thumb you should not connect the same ASIO device ports used for a Monitor in the Control Room for the Main Mix bus. Your monitoring system will be fed by a defined Control Room Monitor, not by an output bus.
The Control Room Mixer
You have correctly configured a Monitor for Cubase 4 now. Go to the "Devices" menu and select "Control Room Mixer" to display it. You will see the "Monitor 1" fader and how it looks in the Control Room Mixer, as configured by you just before.

With this fader you can now control the monitoring volume of your projects, independently from the volume of the Main Mix bus, which is now only used for exporting audio from. In essence you have decoupled the mix volume from the monitoring volume. Besides that, all audio preview functions are now played out by Monitor 1 in the Control Room. Additional features you can use are the "Down Mix" button for quick toggling between mono and stereo or e.g the "Listen" function of the channel mixer. Also individual distribution of the metronome click is at your disposal now. You should assign a key command for the Control Room Mixer to call it up quickly whenever you need it.

We urgently recommend to continue reading about the Control Room in the Cubase 4 Operation Manual. Configuring a Monitor is only the tip of the iceberg of functions and applications in relation to the Control Room!
