The SID pins are mapped to following keys:
16
 
17
   C : Pin A0 = 5V
18
   C#: Pin A1 = 5V
19
   D : Pin A2 = 5V
20
   D#: Pin A3 = 5V
21
   E : Pin A4 = 5V
22
   F : Pin RES# = 5V
23
   F#: Pin D0 = 5V
24
   G : Pin D1 = 5V
25
   G#: Pin D2 = 5V
26
   A : Pin D3 = 5V
27
   A# : Pin D4 = 5V
28
   B : Pin D5 = 5V
29
   C  (next octave): Pin D6 = 5V
30
   C# (next octave): Pin D7 = 5V
31
   D  (next octave): Pin CS# = 0V
32
 
33
The octave doesn't matter, keys are mirroed each second octave.

For historical reasons the pins can also be controlled with a Modulation Wheel,
37
and they are displayed on a LCD. This option hasn't been removed for those people
38
who follow instructions from expired tutorials without reading this README.txt file.
