Okay then that's settled, so what are we talking about a January implementation ??
I don't think we want to wait another year !
So what would be the best way ?
Select/Highlight the bar/s then a right click menu
"Regenerate Selected Bars All Tracks "
"Regenerate Selected Bars >
> Bass RT684 Bass, Electric....
> Drums RealDrums RockHardEven8..
> Guitar 1 RT 522 Guitar, Acoustic....
> UserTrack 1 Guitar, Nylon, Fingerpicking....

Or would it be from the Top track menus and Mixer menus ?

Or All of the above ?

Would you have
"Return to Original Generation"
"Return to Previous Generation"
"Return to Next Generation"
