Added missing S&H smoothing parameter knob.
Fixed mod mappings arrays init, as well as mod dest max value in xml data. Was naming some mod destinations incorrectly when received via sysex, e.g PtchNar. NOTE: Also edited names of envelope loop settings within the xml data, should really be two commits here.
Merge pull request #7 from jclounge/master
