Allocate Channels:

  With this gadget ON you can prevent other music programs from interfering
  with  the  audiochannels.  If you change  the  state  of  this gadget the 
  channels will be (de)allocated when the next module is loaded.

  That is, the  channels will  always be  allocated as  long as there  is a
  module in memory.

  Default is ON.
