If I may suggest that, when you need to perform some tweaking on your audio &/or video files, you'd better go the "DAW" route.
Great news BTW; Gibson stopped developing SONAR from Cakewalk, but BandLab just acquired all rights, and is GIVING (yes FREE!) the latest version under the "Cakewalk" name...
Check here:
https://www.bandlab.com/products/cakewalkPersonaly, I just can't believe it... Sonar Platinum was sold around 350 € and now, it's completely free!
But I installed it on some 4 laptops now... and it works just fine !
EDIT: I forgot to mention: of course, you need to go the "MIDI" route as well to be able to trigger events in Sweetlight. And you can achieve this "internally" on the same PC thru some "MIDI loop" like this one.
