Here it is.
With the board exposed and the keys facing towards you, look at the three big chips. Starting with the upper left pin on the leftmost chip, number the pins 1-14, going down the chip. Number the pins going down the right side of the chip 15-28 (15 top, 28 bottom). The next chip has only one pin that isn’t a duplicate of a point on the first chip. That pin is the third from the top on the left side. Label that point A. The third chip has four points that aren’t duplicates. The second and third points down from the top on the left side, call B and C respectively. The seventh point down on the left is D and the first point on the right side is E.
With me so far?
I’ve arranged 25 switches in rows of five. The first row are all bends for the piano setting. Second is Human Voice, third is Synth Drums, fourth is Brass Ensemble, and fifth is for rhythms and the casiochord setting. While the bends in each row work best on the setting specified, each bend will also work with at least three other voices, and sometimes more.
piano (3,8) (21,22) (5,20) (4,21) (1,10)
human voice (1, C) (13, D) (1,17) (10, 15) (10,22)
Synth Drums (1,14) ( 1,11) (11, 7) (10, 14) (14, B)
Brass Ensemble (1,4) (1,6) (4,17) (10,7) (12,5)
Chord/Rhythm (20,21) (4,6) (8,20) (H,K) (G,J)
Then I’ve got an Atari joystick with 4 as the common point. It goes (4,6) (4,11) (4,20) (4,A) (4,27)
Let me know if you have any questions.
