Midi-mappable undo

[Enorc vs Robot]

I use Live in a one-man-band situation, where I start with some drum tracks and build up music by looping guitar / bass / midi. If I was able to press a single button for undo when I miss the end of a measure or play a sour note, that would be extremely helpful. I know that there are programs out there that can do this (like MIDIYoke), but my laptop is rock solid right now so I'm hesitant to install anything new, and this is something that a ton of live acts would love to have anyway.

Check out Clyphx and it's X-controls.
