How to use the VocALign VST3 plug-ins with Adobe Audition CC.

You must use VocALign Project 3.1.3 VST or VocALign Pro 4.2.3 VST or later with Audition. Earlier versions of VocAlign Project and VocAlign Pro will not work correctly.

The screen shots in this note use VocALign Project 3 as an example. The operating steps are the same for VocALign Pro 4.

1) Install the VST3 version of VocALign to your computer.

2) In Audition choose Effects->Audio Plug-in Manager and click the button 'Scan for Plug-ins'. You should see something similar to the image below.

3) Next you need to add VocALign as an effect to the track that contains your Dub Audio. In the example below we are using  the track that has been named 'Dub'.

The image below shows how the plug-in will appear in Audition. 

4)  Next you need to activate the side chain in VocALign. In the plug-in's window click the 'Side Chain' button (3rd icon from the top left of the window) and set it to 'Mono'. See below...

5) Now you need to route the Guide track to VocALign's side chain. In Audition, click the 'Mixer' tab and then route the Guide track's Send to  VocALign's Side-Chain. See below...

After you have done this you should see something similar to the image below...

5) Now switch back to the 'Editor' tab in Audition. Set Audition's playhead at the start of the audio that you want to capture. Click the button 'Capture Audio' in VocALign and press Play in Audition. You will hear the audio being played and see the playhead moving in VocALign. The green lamp in VocALign will also start to blink.  

Stop playing when you have played the audio that you need.

After you have stopped replay you should see your audio in VocAlign's window. See below...

Click the button 'Edit' in VocALign to see the Aligned audio. You may need to trim the selected audio in VocALign by using the ornage and blue arrows 

Pressing Play in Audition will replay the aligned Dub audio. To hear the original Dub, bypass the plug-in.

For more details on using the VocALign plug-ins please see the manuals at www.synchroarts.com/downloads



VocALign Pro 4 does not work with Digital Performer.

VocALign Project 3 will work using the VocALign menus in Digital Performer but only on OS X not Windows.

VocALign Project 3 and VocALign Pro 4 VST3 plug-ins work with Fruity Loops Studio.

See the following video from a demonstration of its operation. USING VOCALIGN WITH FRUITYLOOPS STUDIO GURU

VocALign Project and VocALign Pro do not work in Final Cut Pro.

If you try to use the VocALign plug-in your Final Cut Pro project may crash.

On the OS X plug-ins can be found in




Just delete any files which start with “VocALign”

VocALign Project and VocALign Pro Audio Unit plug-ins are not processing stereo dub files correctly.

Fixed in: VocALign Project 3.1.2 and VocALign Pro 4.2.2

In Logic Pro X you may not see the Side Chain input at the top of the VocALign Plug-in window.

To display the Side Chain control you need to enable Show Advanced Tools in the Logic Pro X preference panel.

The Side Chain and other control will then be displayed.

To delete the VocALign Project Pro Tools plug-in

For Pro Tools 10 of earlier open the Pro Tools plug-in folder which is 

/Library/Application Support/DigiDesign/Plug-Ins 

and delete the file VocALignPro.dpm

For Pro Tool 11 and later open the folder 

/Library/Application Support/Avid/Audio/Plug-Ins/

and delete the file VocALignPro.aaxplugin

You need to use VocALign Pro version 4.1.5 You can download this version from Downloads

You need to use the latest verison of VocALign Pro. You can download this version from Downloads

In Pro Tools you need to ensure that the playlist option is selected at the top of the AudioSuite window.

If this option is not selected the aligned audio will not be returned to the correct location.

There is an issue in the current versions of Pro Tools 11 and 12 which can result in the length of the output audio created by VocALign being too long. The signal will be followed by an area of silence.

To avoid this issue you need to do the following:

VocALign Project Press the Align button before pressing Spot.

VocAlign Pro< - Press the Process button before pressing Spot.

We are working with Avid to fix this issue in  later versions of Pro Tools.

This note applies to VocALign Pro and VocAlign Project.

When you capture audio that contains silence at its start it may appear as if VocALign has not captured any audio.

However you will notice that the start time at the top left of the VocAlign display will have changed (Assuming you are not capturing from zero). 

If you zoom out or move the scroll bar thumb you will see the audio that has been captured.

The issue occures because VocAlign auto scrolls to the start of the captured audio even if that audio is silence leaving the visible audio off screen. 

You should avoid captureing silence at the start of the Guide and Dub audio as it causes alignment problems.

You need to use VocALign Pro version 4.0 with Pro Tools 6.9 or earlier. You can download this version from VocALign Pro 4.0

Pro Tools -7450 Error on Windows and Mac

This problem affects Pro Tools HD 8.1.1, Pro Tools 8.0.5, Pro Tools 9.0

This problem does not occur in Pro Tools 9.0.1 - 9.0.2 or later and earlier versions of Pro Tools 8 and Pro Tools 7.

VocALign Project and Pro - all versions

When you press the Process button you will see the following:

DAE Error -7450

This is caused by a change in the way Pro Tools supports VocALign.

This can now be fixed by using Pro Tools or please see

Avid Support

If the VocAlign VST3 plug-in is installed but not displayed in Reaper you may need to have Reaper to rescan the VST plug-ins.

Then press Clear cache/re-scan

These instructions appy to the Windows version of SONAR.

If you cannot see VocALign Pro or VocALign Project in Sonar's Region FX Menu there are four things to check:

1) Have you downloaded the correct version of VocALign?

If you are running the 64 bit version of Sonar you will need to install the 64 bit, VST3 version for Windows of VocALign Project or VocALign Pro. Similarly if you are running the 32 bit version of Sonar you will need to install the 32 bit, VST3  version for Windows of VocAlign Project or VocALign Pro.

You can download the installers from: Downloads

 To check which version of Sonar you are using, select Help->About in Sonar. At the bottom of the  window that appears  you will Sonar's version number. If its version number ends in "x64" then you are running the 64 bit version of Sonar. The image below shows the "About window"  from the 64bit version of Sonar Platinum.

2) Has SONAR registered VocALign as a new plug-in?

First, please make sure that you have either activated your computer with a licence for VocALign  or connected an iLok USB key that holds a licence for VocALign to your compter.

For more information on how to authorize VocALign, please see the section "Software Installation and Authorization" in the user manual. You can download the manuals for VocALign Project and VocALign Pro  from: Downloads.

In some cases Sonar will not automatically scan its VST plug-ins as it starts. This means that Sonar may not recognize any recently installed plug-ins, such as VocALign Project or VocALign Pro. To force Sonar to search for new plug-ins:

In Sonar open the "Cakewalk Plug-in Manager" (select Utilities->Cakewalk Plug-in Manager").

Open the VST Configuration -> Options window

Make sure that one of the scan paths is set to 

c:\Program files\common files\vst3

Then select 

Re-scan failed plug-ins


Re-scan existing plug-ins

close the Scan Paths window and then select Scan VST Plug-ins

If VocALign is found an iLok authorisation window may be displayed. You must compete any instructions that are displayed.

Once Sonar has registered the VocALign plug-in successfully, you will be able to select it from the Region FX Menu.

3) Run as Administrator

You should not use Run as Administrator to start SONAR when scanning for new plug-ins.

4) Failed Plug-ins

If VocALign does not appear it is possible you have VST3 plug-in from another manufacture that is stopping SONAR scanning all the plug-ins. You may need to find the failing plug-in and remote it from the VST3 folders.

How to use the VocAlign VST 3 plug-in with SONAR X3

The screen shots in this description use VocALign Project 3, the operating steps are the same for VocAlign Pro 3.

1) Add VocALign as an effect in the track which contains your Dub audio. (In this example its is the second track which has been named Dub.)

This image shows how the plug-in will appear.

You now need to send audio from the Guide track into the VocALign side chain input.

You should now see the following send in the Guide track.

Now set the SONAR playhead at the start of the area you want to capture, select Capture Audio in VocAlign and press Play in SONAR.

You will hear audio being played and see the playhead move in VocALign. Stop playing when the audio you want to process has been played.


You should see your audio in the VocAlign window.

Press Edit to view the aligned audio. You may need to trim your selected audio in VocALign using the orange and blue arrows.

If you press play in SONAR you will hear the aligned audio. To hear the original Dub audio bypass the plug-in. 

For more details on using VocALign see the manual at www.synchroarts.com/downloads

VocALign Project 3 and VocALign Pro 4 VST plug-ins do not currently work with Samplitude.

The capture sequence does not work and the side chain input selector is not displayed by Samplitude.

VocALign Project 3 and VocALign Pro 4 are VST 3 plug-ins.

Sony Vegas does not support VST3 plug-ins.

The other plug-in formats of VocALign (AU, AAX and Audio Suite) are also not supported by Sony Vegas.

This error usually means that the Guide signal had been edited (e.g. cutting it in two or more pieces) since it was last added to VocALign. Although VocALign knows that the Guide has been cut, it cannot know which bit of the cut Guide to use for alignment.  To generate  a valid aligned output, the guide and the dub need to be recaptured  (using "Drag and Drop" or the menus) before any reprocessing. 

If you select the VocALign menu in Studio One you may see the following message.

You need to update to the ARA compatible version of VocALign Pro. You can download the latest version of VocALign Pro from http://www.synchroarts.com/downloads 

If you select the VocALign menu in Studio One you may see the following message.

You need to update to the ARA compatible version of VocALign Project. You can download the latest version of VocALign Project from http://www.synchroarts.com/downloads

Make sure VocALign Pro is not installed on your system as Studio One will select VocALign Pro in preference to VocALign Project.

VocAlign Project and VocALign Pro do not work with Steinberg's WaveLab editor.

VocAlign Project and VocAlign Pro fully work with Steinberg's main editor products Cubase and Nuendo.

Pro Tools 11.2 and 11.3 may crash when loading VocALign or the only the background of the VocALign window may be displayed.

This has been fixed in

VocALign Pro 4.2.4 and VocALign Project 3.1.4

VocALign and Revoice Pro use VST 3 plug-ins.

VST 3 plug-ins are not suported by Pyramix.

The Capture and Spot operations are very slow.

This has been fixed in VocALign Project 3.1.3 AAX and VocALign Pro 4.2.3
