Applied Ken Ellinwood's fix:

I fixed the handling of a MIDI bank select controller 0, e.g., bank
  select MSB (or "coarse" bank select according to my spec).  Prior to
  this fix a channel's bank number was only changed upon reception of
  MIDI bank select controller 32, e.g, bank select LSB (or "fine"
  bank-select according to my spec).
