Can I make LIve's grid follow my timing mistakes?

[janglesoul]

Hi,
To get a loose, human off-the-grid feel I decided to record my guitar-playing with no metronome and the grid turned off.
Now, I wonder if I could create a grid that moves along with my mistakes? So, that for example synth-arps could play along.

Thanks in advance for any input on this!

I might have found something in an older thread:
