I just acquired a bread machine.  I have made two loaves of bread. The crust is hard, rather like eating a cracker.  The bread itself is a little heavier than I would like but still quite acceptable.  I set the machine at BASIC WHITE and crust at MEDIUM.  Should I set it at LIGHT crust?  Any suggestions on how to get an airier (less dense) loaf? Would buttermilk bread be more tender?  I have a recipe for a buttermilk bread.
