Audacity. Sony Vegas (a video editor). A tape/record. It's a pretty basic omission in my opinion. A bit like forgetting to put doorhandles on a car. A real shame, because otherwise Cakewalk is the best DAW I've ever used.
Vegas does this, with the "velocity" automation lane, though I would prefer a "resample" option, where Ctrl+Shift+Drag affects pitch.
Actually, there should be:
1: An audio process effect called "change speed"
2: A "Simple Resample" option along side "Elastique Pro" etc. in the "Preferences>Playback and Recording>Stretch Methods" menu.
