[sdiy] Keyboard Control

[Thomas Holley]

    I have a rather fundamental question. In a keyboard controller resistor ladder, does the high voltage side go to high pitch key or the low pitch key. I have been tinkering with an old keyboard and soldered up a 100 ohm resistor between each key for a nice ladder when it finally dawned on me that I had not a clue which side to put the current source on and which one to ground. Thanks for your help
