If you had space between notes it would be easier work, but even if you don't you should be able to work faster with the TAB to transients feature followed by slicing at the Now Time.
TAB (Navigate to next transient)
SHIFT+TAB (Navigate to previous transient)
S (Slice at Now Time)
Then everything else is basic renaming, applying track names to clips, creating a very short fade in at the beginning of the selected clips so you don't have to be so careful with slices at the Zero-Cross point to prevent pops and clicks. Then a key binding for Export as already suggested.
Here's a little visual example, hope it helps:
