We got through 16 songs with bass edits, new tracks on 4 or 5 tunes, and reamped every single one.  It was an amazing amount of work that we somehow crammed into one session.  I have never felt the Pilotone at the temperature that it got up to by the end of the night.  We even managed to retool a few drum tracks and record a new high hat track.  Very productive day.  We are close to putting this album to bed.
