Synchro Arts have just announced the public beta of VocALign Project 3 and VocALign Pro 4 as AAX plug-ins. They say:
VocALign Project 3 and VocALign Pro 4 are now available as AAX plug-ins.
They are designed to work with Pro Tools 11 and later. They will not work with Pro Tool 10.
They are available for Windows and OS X and support the same operating system versions as Pro Tools 11.
The look and function of the plug-in is nearly identical to the earlier Audio Suite plug-ins which work on Pro Tools 10 and earlier and so the same operating manuals and tutorials can be used.
The AAX plug-ins use the same licences as other plug-in versions of VocALign Project 3 and Pro 4 so current owners of the iLok licences for these products can use the AAX versions at no extra cost.
You must have an VocALign Project 3 or Pro 4 iLok license to use the beta plug-ins.
Very Important Note
There is an issue in the current versions of Pro Tool 11 which can result in the length of the output audio created by VocALign being to long. The signal will be followed by an area of silence.
