 * Copy regions with the sw_previous to be extended (which will include some regions copied in the previous step). Likewise add the amount of shift to sw_previous, lokey and hikey to the copy.
 * Delete the regions with sw_previous above the new max range (or could try avoiding copying them in the first step, but this way is probably safer).
 * Delete the duplicate regions copied in both of the first two steps.
-* Add in regions going from the bottom three values of sw_previous to the notes in the extended range. This is where either some sort of defaults will be needed - using a sample of an ascending octave transition for all intervals over an octave seems to often work fine in practice.
-* Add regions going from the new extended notes to the bottom three pitches, as above.

+There will be no legato samples covering the widest intervals
 from the extended notes to the farthest notes on the other side. If the
 instrument has legato samples only recorded within a certain range (for
