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.

Audio Monitoring Options

Advantages / Disadvantages / Comments

Directly

  • Simple
  • Plays all Revoice Pro audio playback functions: scrub and loop
  • Not slaved to playback in DAW

Indirectly via:

Revoice Pro Monitor Plug-in

  • The output of Revoice Pro is fed to a stereo Insert in a DAW track which can be routed through the DAW's audio monitoring hardware.
  • Works with Pro Tools HD, Nuendo, Cubase, Logic Pro and other DAW hardware (via supported RTAS, VST3 and AU inserts).
  • If DAW is playing, Revoice Pro follows the DAW playback position and replays enabled tracks through the DAW's audio hardware.
  • Revoice Pro Monitor ONLY- When DAW is not playing, the output of Revoice Pro play, scrub and looping functions are played through the DAW's audio hardware.

 

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 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.

 

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).

Audio Settings InternalAudio Output - External

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.

To continue the setup, click link below:

Windows OS Setup

To set the Directly-connected audio hardware, in the Revoice Pro menu bar, in the Edit menu, select Preferences.

The menu similar to that shown below should appear and the user can select the Audio Output drop-down menu to chose Speakers as shown, or any other directly connected audio hardware that appears in the list.

Preferences - Windows

The next section describes how to set up monitoring Revoice Pro through your DAW audio hardware (indirectly connected), if you have installed the Revoice Pro Monitor plug-in.

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:

  1. 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.
  2. 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).
  3. 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

Monitoring with Revoice Pro monitor

 

Setting up Revoice Pro Monitor plug-in Pro Tools

  1. Add a stereo Aux track into your DAW session. (The Monitor plug-in only works with stereo tracks)
  2. 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)
    Monitor Setup in Pro Tools
    WARNING: Do not confuse this plug-in with the Revoice Pro (stereo) plug-in under Instrument, which is the Rewire version.

  3. Note that the Revoice Pro Monitor plug-in (as shown for Pro Tools below) has no controls.

Monitor Plug-in Controls

  1. To enabling the Monitor, switch it on using the Monitor Enable button shown ON below

Monitor Switch shown on

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.

Disable PT11 Dynamic Plug-in Processing

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 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.
