Audio Monitoring
Because Revoice Pro is a stand-alone program, the audio playback needs to be directed to a monitoring system to be heard.
Revoice Pro can route its stereo mix of enabled tracks in two basic ways.
- Directly - to audio hardware supported by your computer's operating system.
- Indirectly - by feeding Revoice Pro's stereo output to a track Insert in your DAW (if it supports RTAS or VST3 insert plug-ins) and routing the output of that track to your DAW monitor system. This method uses the Revoice Pro Monitor plug-in or a Rewire Plug-in (Mac only).

Both of these methods can be set up at the same time, but only one at a time can be used, depending on whether the Monitoring switch, for Revoice Pro Monitor or Rewire (Mac only) is ON or OFF in Revoice Pro. This is described in detail below.
Setting Audio Output Options
The Audio Output settings are controlled in the Revoice Pro Preferences menu.
- Go to Mac OS Setup
- Go to Windows OS Setup
Mac OS Setup
To set the Directly-connected audio hardware, in the Revoice Pro menu bar, under Revoice Pro, select Preferences and then the General tab.
The menu similar to that in the first image below should appear and the user can select the Audio Output Device drop-down menu to chose Built-in Output or other directly connected audio hardware listed as shown in the second image below (in this example, an Mbox 2 is being selected).
NOTE: This does NOT apply to Pro Tools HD hardware, which is discussed separately below.
To set up monitoring Revoice Pro through your DAW audio hardware (indirectly connected), select the drop-down menu under "External Audio Monitoring". If you have installed the Revoice Pro Monitor and Rewire plug-ins, there will be two options.
Set the menu as shown above to select the Revoice Pro Monitor Plug-in.
MAC ONLY - To select the Rewire plug-in, set the External Audio Monitoring drop down as shown below:
To continue the setup, click links below:

Revoice Pro Monitor plug-in
This section explains how to listen to Revoice Pro's playback through Pro Tools or VST3-based DAW hardware.
NOTE: This method works with Pro Tools HD hardware.
The main functions are:
- If the DAW is not playing, Revoice Pro controls the playback in Revoice Pro.
This method also plays back scrubbing and looping within Revoice Pro. - If the DAW starts to play, Revoice Pro also plays back, following the DAW's play head location.
(Audio synchronization is sample accurate on the systems we have tested). - NOTE: Starting Revoice Pro playback does not put the DAW into play mode.
(This is the one disadvantage of this system compared to using the Rewire monitor plug-in.)
Overview and functions of the Revoice Pro Monitor plug-in
Setting up Revoice Pro Monitor plug-in Pro Tools
- Add a stereo Aux track into your DAW session. (The Monitor plug-in only works with stereo tracks)
- Insert the Revoice Pro Monitor plug-in into the track as shown below in the example for Pro Tools.
The plug-in in Pro Tools is under:
multichannel plug-in / Other / Revoice Pro Monitor (stereo)
WARNING: Do not confuse this plug-in with the Revoice Pro (stereo) plug-in under Instrument, which is the Rewire version.
- Note that the Revoice Pro Monitor plug-in (as shown for Pro Tools below) has no controls.
- To enabling the Monitor, switch it on using the Monitor Enable button shown ON below
If you switch this Monitor switch OFF, then the output will be sent to the directly connected device set up as the Audio Output.
PRO TOOLS 11 WARNING: In Pro Tools 11 you must disable (untick) Dynamic Plug-In Processing in the Playback Engine window shown below. Otherwise, Pro Tools will stop getting audio from the plug-in after a period of silence.

Setting up Revoice Pro Monitor plug-in VST3
These instructions are for Cubase but should also apply to other VST3 hosts.
Instructions for Nuendo differ slightly and are provided here.
1) In Cubase select the Devices -> VST Instruments menu item.
2) The VST Instruments dialog will be displayed.
3) Select one of the entries in the dialog and a menu will be displayed showing the available instruments. Select Revoice Pro Monitor.
4) You will be asked if you want to create a MIDI track you can select Cancel.
5) The Revoice Pro Monitor will be displayed in a window.
6) In Revoice Pro check that the monitor button is enabled.
7) In Cubase check the Release Driver when Application is in Background option is not checked.
If this option is checked when you try and start playing from Revoice Pro the operaiton will fail because Cubase is in the background.
You should now be able to start playing from Revoice Pro or from Cubase.

Monitoring through Rewire (Mac ONLY)
- You can use Rewire to send audio from Revoice Pro into your Audio Editor.
- This allows monitoring directly out of your audio hardware and synchronized playback with your Audio Editor.
When using Rewire, Revoice Pro is the Rewire Source Application (sometimes called "Slave") and your Audio Editing software (e.g. Pro Tools, Logic, Cubase, Nuendo, etc.) is the Rewire Host Application (sometimes called "Mixer").
Installation of Rewire
Make sure the Revoice Pro Preference window shows Rewire as selected under "External Audio Monitoring"
To check for, or install rewire - run Revoice Pro and press the Rewire on/off button which is located as shown here in the red circle:
OFF
ON
- An automatic check will be made to see if the correct version of Rewire is installed. The correct version will be installed if required. (Revoice Pro currently installs Rewire Version 1.8.2, build 127 - or higher)
- Stop all audio applications running.
- Go to the folder "/Library/Application Support/Propellerhead Software/Rewire".
- Delete or rename the file Rewire.bundle.
- Start Revoice Pro and press the Rewire button.
- Revoice Pro is a 32 and 64 bit application. Your host (Audio Editor) application must be running in the same mode (32 or 64 bit.)
Possible Error:
If during Revoice Pro's Rewire installation you see a "Failed to write" error and you are asked about read/write permissions, do the following.
The correct version of the file should then be installed.
Possible Error:
If your Rewire host (Audio Editor) is running in 32 bit mode and you you press the Revoice Pro Rewire control and see the following message,
then you need to Stop Revoice Pro and set it to run in 32 bit process mode. To do this:
- Locate the Revoice Pro application on your disk.
- LEFT CLICK to display menu with "Get Info" and select it.
- Set "Open in 32-bit mode" as shown in the picture below
- Start Revoice Pro and press the Rewire button.
The correct version of the file should then be installed.
NOTE: Revoice Pro Scrubbing and looping will not work with Rewire ON because the Host DAW will not correctly support it .

Timecode Offsets affect Rewire operation
If your Audio Editor's Session Start timecode does not start at 0:0:0:0 (as shown, for example, in the Pro Tools Session Setup window below) you may have to apply a "Rewire Timecode Offset" in Revoice Pro.
The effect of having a timecode offset between the host and Revoice Pro is that during playback, the timecode of the host will be offset from the timecode in Revoice Pro, and the audio playback will be out of sync by the offset amount.
To set the Rewire Timecode Offset
Select the Revoice Pro View menu and select Settings as shown right.
A Settings menu similar to that below should appear showing the current Rewire Timecode Offset which in the example is at zero.
Enter the amount of time displayed as the "Session Start" (or equivalent) offset in the Audio Editor (i.e. Rewire Host) into the box in Revoice Pro Settings panel labelled Rewire Timecode Offset as shown in the example below with a 1 hour offset.

Monitoring through Pro Tools HD hardware
There is currently a range of Pro Tools HD audio hardware that does not allow 3rd party audio inputs when Pro Tools is running. All versions of Pro Tools HD currently do NOT offer a 'release audio' function. The DAE engine in HD takes over the computer, and while Pro Tools is open, only allows PT to pass audio through the Digidesign hardware.
In this case, using the Revoice Pro Monitor plug-in is a good option, but another options the user can try is a Digital Audio Link between the Mac and the HD hardware.
Digital Audio Link
(This has been reported working with Pro Tools HD 10.1.2 with HDX hardware and multiple HD
interfaces on a MacPro 2008 8-core running Mac OS 10.7.3).
A simple HOSA TOSlink to AES-converter can be connected between the TOSlink digital output of the Mac and one of the
AES inputs on an AVID HD interface. Also, the sample rate converter on that AES input can be used to integrate
the asynchronous digital output signal of the Mac. Or you can
clock the Mac to a TOSlink S/Pdif signal on the digital input (you need
to use an "Aggregate device" using just the stereo digital input and
output of the Mac in the AudioMIDI setup of OS X to achieve this). Most lower-end audio interfaces have a TOSlink S/Pdif input.
Then, in Pro Tools you need an open aux input for the stereo AES input
signal.
