Kroll had the following to say on his experience of using X2Pro ... "I have to say, I've now used X2Pro several times and am very impressed with it. Each time, I find myself less anxious about translation issues as it still has a perfect record as far as my projects are concerned."
X2Pro is only available on the Mac App Store at £99.99/$149.99. X2ProLE is a lower cost version for those who do not need audio files referenced, media trimmed, or close control of the conversion of Roles. X2ProLE users can upgrade to the full Pro version with an In App Purchase.
