VOICE ONE

1061: tone data
      bits 7-8: nothing
      bits 5-6: 00/01/10 = duty 1/2/3
      bits 1-4: gate 0-9

1062: bit    8: on=d  off=u
      bits 5-7: time 0 to 7
      low  1-4: gain $0 to $f

1063: bit    8: modulation: wave
                  off = sine/random
                  on  = square
      bits 1-7: depth $0-$63

1064: bit    8: modulation: wave
                  off = sine/square

   	  bits 1-7: frequency $0-$63

1065: voice one notes
        00 = off : 01 = c3 : 02 = c#3 etc : 25 = c5

1075: bit pattern indicates l/c/r for voice 1
        2 bits per note
        00 = left : 01 = centre : 10 = right

VOICE TWO

108a: bit    8: modulation: wave
                  off = sine/random
                  on  = square     
      bits 1-7: depth $0-$63       
                                   
108b: bit    8: modulation: wave
                  off = sine/square

      bits 1-7: frequency $0-$63   

108c: voice two notes
        as voice one

109c: voice two stereo data
        as voice one

10a0: voice one/two loop lengths
        high nibble v1, low nibble v2
        length stored $1-$f, displayed 2d-16d

NOISE

10a1: tone data
      bit    8: on=d  off=u
