Alternative version with a tone array 

tone array:
   text	   data	    bss	    dec	    hex	filename
      0	  25698	      0	  25698	   6462	satan_newsboytko.hex
0x6480 bytes written into 0x7000 bytes memory (89.73%).

note on array:
   text	   data	    bss	    dec	    hex	filename
      0	  25802	      0	  25802	   64ca	satan_newsboytko.hex
0x6500 bytes written into 0x7000 bytes memory (90.18%).
